If the Solarmount-I system is used grounding is achieved with the UniRac UGC-2 1/4- that carries current in normal operation,which is connected to ground(or earth). In a polyphase or three-wire(single-phase) AC system,the 20 bolt and flanged nut torqued to 120 in-lbs. When using methods 2,3,4 or 5 the array frame(racking). neutral conductor is intended to have similar voltages to each of the other circuit conductors. By this definition,a circuit must have at least three wires for one to serve as a neutral. In the electrical trade,the conductor of a 2-wire circuit that is connected to the supply neutral point and earth ground is also referred to as the"neutral".[I]The NEC and Canadian electrical code only define neutral as the first of these. In North American use,the second definition is used in less formal language but not in official specifications. In the UK the IET definition of a neutral conductor is one connected to the supply system neutral point,which includes both these uses.All neutral wires of the same electrical system should have the same electrical potential,because they are all connected through the system ground.Neutral conductors are usually insulated for the same voltage as the line conductors,with interesting exceptions.[2] Ufer around Circuitry Neutral wires are usually connected at a neutral bus within panelboards or switchboards, and are"bonded"to earth ground at either the The Ufer Ground is an electrical earth grounding method developed during World War II.lt uses a concrete-encased electrical service entrance,or at transformers within the system. For electrical installations with three-wire single phase service,the neutral electrode to improve grounding in dry areas.Thetechnique is used in construction of concrete foundations. point of the system is at the center-tap on the secondary side of the service transformer. For larger electrical installations, such as those with polyphase service,the neutral point is usually at the common connection on the secondary side of delta/wye connected transformers. Other Construction: Concrete is naturally basic(has high pH). Ufer observed this means that it had a ready supply of ions and so arrangements of polyphase transformers may result in no neutral point,and no neutral conductors.Combining neutral with earth Stray voltages provides a better electrical ground than almost any type of soil. Ufer also found that the soil around the concrete became created in grounding(earthing)conductors by currents flowing in the supply utility neutral conductors can be troublesome. For example, "doped",and its subsequent rise in pH caused the overall impedance of the soil itself to be reduced.[3]The concrete special measures may be required in barns usedfor milking dairy cattle.Very small voltages, not usually perceptible to humans, may cause low enclosure also increases the surface area of the connection between the grounding conductor and the surrounding soil, milk yield,or even mastitis (inflammation of the udder).[3] So-called "tingle voltage filters" may be required in the electrical distribution which also helps to reduce the overall impedance of the connection. system for a milking parlour.Connecting the neutral to the equipment case provides some protection against faults, but may p roduce a dangerous voltage on the case if the neutral connection is broken.Combined neutral and ground conductors are commonly used in electricity Ufer's original grounding scheme used copper encased in concrete.However,the high pH of concrete often causes the supply companies'wiring and occasional) for fixed wiring in buildings and for some specialist applications where there is I ittle alternative, copper to chip and flake. For this reason,steel is often used instead of copper.When homes are built on concrete slabs,it such y p g y g g p pp such as railways and trams. Since normal circuit currents in the neutral conductor can lead to objectionable or dangerous differences between is common practice to bring one end of the rebar up out of the concrete at a convenient location to make an easy local earth potential and the neutral,and to protect against neutral breakages,special precautions such as frequent rodding down to earth connection point for the grounding electrode.[4]Ufer grounds,when present,are preferred over the use of grounding rods. (multiple ground rod connections), use of cables where the combined neutral and earth completely surrounds the phase conductor(s),and In some areas(like Des Moines, Iowa) Ufer grounds are required for all residential and commercial buildings.[5]The thicker than normal equipotential bonding must be considered to ensure the system is safe. conductivity of the soil usually determines if Ufer grounds are required in any particular area. Shared neutral An Ufer ground of specified minimum dimensions is recognized by the U.S.National Electrical Code as a grounding A shared neutral is a connection in which a plurality of circuits use the same neutral connection.This is also known as a common neutral, and electrode.[6]The grounding conductors must have sufficient cover by the concrete to prevent damage when dissipating the circuits and neutral together are sometimes referred to as an Edison circuit. high-current lightning strikes.[7] Sinele phase A disadvantage of Ufer grounds is that the moisture in the concrete can flash into steam during a lightning strike or similar Main article: Split-phase electric power In split phase wiring, for example,a duplex receptacle in a kitchen,devices may be connected with a high energy fault condition.This can crack the surrounding concrete and damage the building foundation.[8] cable that has three conductors, in addition to ground.The three conductors are usually coloured red,black,and white. The white serves as a common neutral,while the red and black each feed,separately,the top and bottom hot sides of the receptacle:Typically such receptagjl s are supplied from two circuit breakers in which the handles of two poles are tied together for a common trip. If two large appliances arekl it t'' once,current passes through both and the neutral only carries the difference in current.The advantage is that only three wires are regiiirudto X serve these loads, instead of four. If one kitchen appliance overloads the circuit,the other side of the duplex receptacle,will be shut off as well. This is called a multiwire circuit.Common trip is always required if there are loads that use more than one phase simvltaneo-usly. The common Slingshot Power,Contractor trip prevents overloading of the shared neutral if one device draws more than rated current. & - Equipment in this Photovoltaic System slingshG>t. 10.29 kW PV System 1Story Curved Tile Torque Information & Grounding Inforr tiow.

The language of this section states that the fire classification of PV systems must match the minimum FIRE CLASSIFICATION FOR ROOF MOUNTED SOLAR PHOTOVOLTAIC required fire classification of the roof assembly over which they are mounted as required in IBC Section PANELS/MODULES [SYSTEMS]AND APPLICATION OF THE 2013 CALIFORNIA 1505. With any rooftop structure, the PV structure should not degrade the fire resistance properties of BUILDING STANDARDS CODE the roof, so as not to place the building and its inhabitants at an unanticipated risk. However, straightforward implementation of this requirement is not possible for the following reason(s). On January 1, 2014 the 2013 Califomia Building Standards Code, California Code of Regulations (CCR), Title 24, became effective. As part of the 2013 California Building Standards Code, Part 2 and PV modules are a component of a rooftop mounted PV system and, although PV modules can receive a Part 2.5 provisions for the fire classification of roof mounted photovoltaic panels/modules[systems]were fire classification rating in accordance with UL 1703, there are currently no PV systems with a fire updated to comply with the most recent edition of Underwriters Laboratories Inc. (UL) 1703 Standard for classification rating. Thus, as currently written, Section 1509.7.2 refers to the fire classification rating of Flat-Plate Photovoltaic Modules and Panels published in October 2013, a system,and this exact approach is not yet achievable. The Office of the State Fire Marshal(OSFM)was recently informed by industry that presently there is an In the absence of a PV system fire rating, it may seem appropriate to substitute the PV module fire insufficient supply of UL 1703 compliant Class A, Class B or Class C fire rated tested and listed classification rating in order to achieve the desired result, which is the preservation of the roof photovoltaic panels/modules [systems] to meet present demand. This circumstance may prohibit the assembly's original fire classification. However,simply using the PV module fire classification rating may permitting of projects to install solar photovoltaic systems on roofs,which in tum curtails efforts to meet not provide the desired result in most cases. current sustainability goals. The issuance of the most recent edition of UL 1703 and its adoption into the Over the past five years, rigorous testing by UL and Solar ABCs revealed that the performance of a 2013 California Building Code(CBC), specifically Section 1505.9 and California Residential Code(CRC) system (which includes PV modules on standoff mounted racks)exposed to fire or flame is not the same Section R902.4 necessitates the need for guidance from the OSFM on this matter. These sections read as that of a module alone. Currently, modules receive a fire classification rating based on testing the in part: module alone, not as part of a PV system. The results of these tests show that actual performance of a "Rooftop mounted photovoltaic panels and modules(systems)shall be tested, listed rack-mounted PV system exposed to fire or flame is strongly dependent on the mounting geometry of and identified with a fire classification in accordance with UL 1703..." the PV array and properties of the components that make up the speck PV module type,but the results are not necessarily dependent on the fire classification rating of the module. (A summary of this research In view of the effective date of the building standards identified above, and to provide suitable time for is published in a Solar ABCs report available at: the testing and listing of photovoltaic panels/modules [systems]to meet the current UL 1703 standard, http://www.solarabr-s.org/about/publications/reports/flammability-testing/index.html) the Office of the State Fire Marshal recommends that local authority having jurisdiction accept photovoltaic panels and modules having a Class C rating under the previous version of UL 1703 (2002 As a result of this testing and in consideration of the current requirements of IBC Section 1509.7.2, a edition with revisions through April 2008)or UL 790 (2004 edition with revisions through October 2008). working group composed of representatives from the PV industry, the roofing industry, standards This recommendation is based on the photovoltaic testing that was done during the past five years by development, the building and fire enforcement community, and government laboratory experts UL and Solar America Board for Codes and Standards (Solar ABCs) and is discussed in the developed and proposed a new test methodology to determine fire classification ratings for PV systems. "Background and Justification"section of this bulletin. The new test methodology was adopted by the ANSI/UL 1703 Standard Technical Panel, and was published October 25,2013. Background and Justification: The 2013 California Building and Residential Code as noted above are primarily based on national Proposed Emergency Regulations: model codes promulgated and published by the International Code Council and in turn adopted by The Office of the State Fire Marshal is presently developing emergency building standards to temporarily reference into Title 24 Parts 2 and 2.5. The promulgation of these model codes provided the basis for stay the effective date of CBC Section 1505.9 and CRC Section R902.4 for 180 days. This proposed the provisions relating to PV in the California Codes. The 2012 International Building Code (IBC) rulemaking is anticipated to be before the California Building Standards Commission for action at its Section 1509.7.2 includes requirements for fire classification of rooftop mounted photovoltaic (PV) scheduled April 22, 2014 meeting. This information bulletin serves as an interim alternative providing systems and the 2012 International Residential Code(IRC)Section M2302.2.1 includes requirements for guidance until such action can be accomplished. noncombustible or fire-retardant materials.

In the electrical trade,the conductor of a 2-wire circuit that is connected to the supply neutral point and earth ground is also referred to as the"neutral".[I]The NEC and Canadian electrical code only define neutral as the first of these.In North American use,the second definition is used in less formal language but not in official specifications. In the UK the IET definition of a neutral conductor is one connected to the supply system neutral point,which includes both these uses.All neutral wives of the same electrical system should have the same electrical potential,because they are all connected through the system ground.Neutral conductors are usually insulated for the same voltage as the line conductors,with interesting exceptions.[2] Ufer eround Circuitry Neutral wires are usually connected at a neutral bus within panelboards or switchboards,and are"bonded"to earth ground at either the The Ufer Ground is an electrical earth grounding method developed during World War H.It uses a concrete-encased electrical service entrance,or at transformers within the system.For electrical installations with three-wire single phase service,the neutral electrode to improve grounding in dry areas.Thetechnique is used in construction of concrete foundations. point of the system is at the center-tap on the secondary side of the service transformer.For larger electrical installations, such as those with polyphase service,the neutral point is usually at the common connection on the secondary side of delta/wye connected transformers.Other Construction: Concrete is naturally basic(has high pH).Ufer observed this means that it had a ready supply of ions and so arrangements of polyphase transformers may result in no neutral point,and no neutral conductors.Combining neutral with earth Stray voltages provides a better electrical ground than almost any type of soil.Ufer also found that the soil around the concrete became created in grounding(earthing)conductors by currents flowing in the supply utility neutral conductors can be troublesome.For example, "doped",and its subsequent rise in pH caused the overall impedance of the soil itself to be reduced.[3]The concrete special measures may be required in barns usedfor milking dairy cattle.Very small voltages,not usually perceptible to humans, may cause low enclosure also increases the surface area of the connection between the grounding conductor and the surrounding soil, milk yield,or even mastitis(inflammation of the udder).[3]So-called"tingle voltage filters"may be required in the electrical distribution which also helps to reduce the overall impedance of the connection. system for a milking parlour.Connecting the neutral to the equipment case provides some protection against faults,but may produce a dangerous voltage on the case if the neutral connection is broken.Combined neutral and ground conductors are commonly used in electricity Ufer's original grounding scheme used copper encased in concrete.However,the high pH of concrete often causes the supply companies'wiring and occasionally for fixed wiring in buildings and for some specialist applications where there is 1 ittle alternative, copper to chip and flake.For this reason,steel is often used instead of copper.When homes are built on concrete slabs,it such as railways and trams. Since normal circuit currents in the neutral conductor can lead to objectionable or dangerous differences between is common practice to bring one end of the rebar up out of the concrete at a convenient location to make an easy local earth potential and the neutral,and to protect against neutral breakages,special precautions such as frequent rodding down to earth connection point for the grounding electrode.[4]Ufer grounds,when present,are preferred over the use of grounding rods.

This is called a multiwire circuit. Common trip is always required if there are loads that use more than one phase simultaneously.

The language of this section states that the fire classification of PV systems must match the minimum FIRE CLASSIFICATION FOR ROOF MOUNTED SOLAR PHOTOVOLTAIC required fire classification of the roof assembly over which they are mounted as required in IBC Section PANELS/MODULES [SYSTEMS] AND APPLICATION OF THE 2013 CALIFORNIA 1505. With any rooftop structure, the PV structure should not degrade the fire resistance properties of BUILDING STANDARDS CODE the roof, so as not to place the building and its inhabitants at an unanticipated risk. However, straightforward implementation of this requirement is not possible for the following reason(s). On January 1, 2014 the 2013 California Building Standards Code, California Code of Regulations (CCR), Title 24, became effective. As part of the 2013 California Building Standards Code, Part 2 and PV modules are a component of a rooftop mounted PV system and, although PV modules can receive a Part 2.5 provisions for the fire classification of roof mounted photovoltaic panels/modules[systems]were fire classification rating in accordance with UL 1703, there are currently no PV systems with a fire updated to comply with the most recent edition of Underwriters Laboratories Inc. (UL) 1703 Standard for classification rating. Thus, as currently written, Section 1509.7.2 refers to the fire classification rating of Flat-Plate Photovoltaic Modules and Panels published in October 2013. a system, and this exact approach is not yet achievable. The Office of the State Fire Marshal (OSFM)was recently informed by industry that presently there is an In the absence of a PV system fire rating, it may seem appropriate to substitute the PV module fire insufficient supply of UL 1703 compliant Class A, Class B or Class C fire rated tested and listed classification rating in order to achieve the desired result, which is the preservation of the roof photovoltaic panels/modules [systems] to meet present demand. This circumstance may prohibit the assembly's original fire classification. However, simply using the PV module fire classification rating may permitting of projects to install solar photovoltaic systems on roofs, which in turn curtails efforts to meet not provide the desired result in most cases. current sustainability goals. The issuance of the most recent edition of UL 1703 and its adoption into the Over the past five years, rigorous testing by UL and Solar ABCs revealed that the performance of a 2013 California Building Code (CBC), specifically Section 1505.9 and California Residential Code (CRC) system (which includes PV modules on standoff mounted racks)exposed to fire or flame is not the same Section R902.4 necessitates the need for guidance from the OSFM on this matter. These sections read as that of a module alone. Currently, modules receive a fire classification rating based on testing the in part: module alone, not as part of a PV system. The results of these tests show that actual performance of a `Rooftop mounted photovoltaic panels and modules[systems]shall be tested, listed rack-mounted PV system exposed to fire or flame is strongly dependent on the mounting geometry of and identified with a fire classification in accordance with UL 1703...' the PV array and properties of the components that make up the specific PV module type, but the results are not necessarily dependent on the fire classification rating of the module.
