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".[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] 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 electrical The Ufer Ground is an electrical earth grounding method developed during World War II.It uses a concrete-encased service entrance,or at transformers within the system. For electrical installations with three-wire single phase service,the neutral point of the electrode to improve grounding in dry areas.Thetechnique is used in construction of concrete foundations. 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 arrangements Construction: Concrete is naturally basic(has high pH).Ufer observed this means that it had a ready supply of ions and so of polyphase transformers may result in no neutral point,and no neutral conductors. Combining neutral with earth Stray voltages created in provides a better electrical ground than almost any type of soil.Ufer also found that the soil around the concrete became grounding(earthing)conductors by currents flowing in the supply utility neutral conductors can be troublesome.For example,special measures "doped",and its subsequent rise in pH caused the overall impedance of the soil itself to be reduced.[3]The concrete may be required in barns usedfor milking dairy cattle.Very small voltages, not usually perceptible to humans,may cause low milk yield, or enclosure also increases the surface area of the connection between the grounding conductor and the surrounding soil, even mastitis(inflammation of the udder).[3]So-called "tingle voltage filters" may be required in the electrical distribution system for a milking which also helps to reduce the overall impedance of the connection. 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 supply companies'wiring and Ufer's original grounding scheme used copper encased in concrete.However,the high pH of concrete often causes the occasionally for fixed wiring in buildings and for some specialist applications where there is little alternative,such as railways and trams. Since copper to chip and flake.For this reason,steel is often used instead of copper.When homes are built on concrete slabs,it normal circuit currents in the neutral conductor can lead to objectionable or dangerous differences between local earth potential and the neutral, is common practice to bring one end of the rebar up out of the concrete at a convenient location to make an easy and to protect against neutral breakages,special precautions such as frequent rodding down to earth(multiple ground rod connections),use of connection point for the grounding electrode.[4]Ufer grounds,when present, are preferred over the use of grounding rods. cables where the combined neutral and earth completely surrounds the phase conductor(s),and thicker than normal equipotential bonding must In some areas(like Des Moines,Iowa)Ufer grounds are required for all residential and commercial buildings.[5] The be considered to ensure the system is safe. LULRYIN conductivity of the soil usually determines if Ufer grounds are required in any particular area. `3uilding DeDBrtrn r 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. -°y high-current lightning strikes.[7] HEl�IEViEla t-:OR CODE COMPl_IAN Single chase 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,deykce4_rfy§p,connec'tg 1,with�G�f� 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 whifti serves as a common neutral,while the red and black each feed,separately, the top and bottom hot sides of the receptacle.Typically such receptacles are supplied from two circuit breakers in which the handles of two poles are tied together for a common trip. If two large appliances are used at once,current passes through both and the neutral only carries the difference in current.The advantage is that only three wires are required to 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 simultaneously. The common Slingshot Power,Contractor trip prevents overloading of the shared neutral if one device draws more than rated current.

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 follo,:ng reason(s). On January 1, 2014 the 2013 California Building Standards Code.

The issuance of the most recent edition of JL 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`lame is not the same Section R902.4 necessitates the need for guidance from the OSFM on this matter.
