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".[1]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] Circuitry Ufer ground Neutral wires are usually connected at a neutral bus within panelboards or switchboards, and are"bonded" to earth ground at either the electrical service entrance,or at transformers within the system. For electrical installations with three-wire single phase service, the neutral The Ufer Ground is an electrical earth grounding method developed during World War II.It uses a concrete-encased 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 electrode to improve grounding in dry areas.Thetechnique is used in construction of concrete foundations. arrangements of polyphase transformers may result in no neutral point,and no neutral conductors.Combining neutral with earth Stray voltages Construction: Concrete is naturally basic(has high pH). Ufer observed this means that it had a ready supply of ions and so created in grounding(earthing) conductors by currents flowing in the supply utility neutral conductors can be troublesome. For example, provides a better electrical ground than almost any type of soil.Ufer also found that the soil around the concrete became special measures may be required in barns usedfor milking dairy cattle. Very small voltages, not usually perceptible to humans, may cause low "doped",and its subsequent rise in pH caused the overall impedance of the soil itself to be reduced.[3] The concrete milk yield,or even mastitis (inflammation of the udder).[3] So-called "tingle voltage filters" may be required in the electrical distribution enclosure also increases the surface area of the connection between the grounding conductor and the surrounding soil, system for a milking parlour.Connecting the neutral to the equipment case provides some protection against faults,but may produce a which also helps to reduce the overall impedance of the connection. dangerous voltage on the case if the neutral connection is broken. Combined neutral and ground conductors are commonly used in electricity supply companies' wiring and occasionally for fixed wiring in buildings and for some specialist applications where there is little alternative, Ufer's original grounding scheme used copper encased in concrete. However, the high pH of concrete often causes the such as railways and trams. Since normal circuit currents in the neutral conductor can lead to objectionable or dangerous differences between copper to chip and flake. For this reason,steel is often used instead of copper.When homes are built on concrete slabs, it local earth potential and the neutral, and to protect against neutral breakages, special precautions such as frequent rodding down to earth c common practice to e.F one end of the rel is u out of the concrete at convenient location to make an concrete (multiple ground rod connections), use of cables where the combined neutral and earth completely surrounds thii_*ase conduct ftPER "` P g P Y '—"ry.:r connection point for the groundingelectrode.[4] Ufer rounds, when resent,are referred over the use of groundingrods. thicker than normal equipotential bonding must be considered to ensure the system is safe. � ' ' Hr„ ;�ailGir,y p�D2p In some areas(like Des Moines, Iowa) Ufer grounds are required for all residential and commercial buildings.[5] The ...r, conductivity of the soil usually determines if Ufer grounds are required in any particular area.

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 simultaneously. The common trip prevents overloading of the shared neutral if one device draws more than rated current.

California State Fire Marshal California State Fire Marshal Information Bulletin 14-002 Information Bulletin 14-002 Issued: February 14,2014 The requirements of the IBC Section 1509.7.2 will need careful examination in its application. 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. (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. httpltwww.solarabcs.org/abouVpublicationstreports/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 � �� r ra I Is 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 systemsL_t - rU C?Pp� int "Background and Justification"section of this bulletin.
