Article 27 of the BOCA Basic Building Code/1996 is incorporated herein by reference as part of the Electric Code of Montgomery Township. All references to the term "Building Official" shall be amended to read "Code Enforcement Official or his assistant or designee," and, where the words "NFPA 70" appear, it shall read instead "the Electric Code of Montgomery Township." The National Electric Code/1996 and Article 27 of the BOCA Basic Building Code, together with the provisions of this Article IV of this chapter shall collectively comprise and be referred to as the Electric Code of Montgomery Township.
A. 
Notwithstanding anything to the contrary contained in the National Electric Code/1996 or Article 27 of the BOCA National Building Code/1996 or in any of the codes and ordinances of Montgomery Township, in no event and under no circumstance shall the use of aluminum conductors be permitted in any way in any building heretofore or hereinafter erected in Montgomery Township, except as follows:
(1) 
Service conductor: Aluminum service conductors shall be permitted to extend from a point of contact with the local utility company through exterior meter sockets to a point inside the building or structure at the line side of the service disconnect. Service conductors may enter the building or structure either underground or on the exterior of the building or structure.
(2) 
Aluminum conductors may be extended from the service panel to locations of wiring systems, provided that the following procedures are followed:
(a) 
All aluminum conductors shall be a minimum of number six stranded A.W.G. (American Wire Guide).
(b) 
Aluminum conductors are to be terminated only at an accessible point with no splices between the service panel and the termination point.
(c) 
All aluminum conductors are to have an oxide-inhibiting joint compound applied to all termination points and splices.
(d) 
Terminal lugs or aluminum to copper pigtails shall be connected to aluminum conductors by compression-type fittings on all conductors larger than or equal to number six A.W.G. (American Wire Guide). However, aluminum conductors smaller than or equal to 0000 A.W.G. may be connected by other than compression-type fittings at meter sockets and line side service disconnects, for one-hundred-ampere, one-hundred-fifty-ampere and two-hundred-ampere services, where space does not permit the use of compression-type fittings.
(e) 
Twist-on wire nut connectors shall not be permitted on any aluminum conductors.
(f) 
Aluminum and copper conductors shall not be in contact with each other at any point in the electrical system.
(g) 
Aluminum lugs shall be connected to aluminum bussbars with aluminum bolts and heavy flat aluminum washers, or with steel bolts and heavy flat cadmium washers and ball valve spring washers. Connections of aluminum terminal lugs to copper bussbars shall be made with steel bolts, heavy flat cadmium-plated washers and ball valve spring washers. Aluminum lug connections to equipment pads having copper studs shall employ flat cadmium-plated washers and ball valve spring washers.
(h) 
Equipment. Meter socket load centers, distribution panels, breakers and all other equipment used with aluminum conductors shall be Underwriter Laboratory Listed AL/CU.
(i) 
Aluminum conductors shall not be used for exterior grounding connectors.
(j) 
Aluminum termination shall be made only under manufacturer's instruction on all appliances. In no case shall aluminum wire terminate on a range; instead, aluminum feed shall terminate to range receptacle devices, suitable for aluminum connection, and then an appliance cord shall be used.
B. 
Metal raceways shall be provided Type NM cable at the following locations in all new residential dwellings: exposed basement walls, hot-water heaters, garbage disposal units and oil burners.
C. 
No electrical wiring system may be used or electric current supplied to any lot, piece of ground, building or structure in Montgomery Township until an authorized underwriter company provides proof that the electrical plans have been approved and issues a certificate of inspection following construction. This is in addition to and not in lieu of a permit from Montgomery Township. The Board of Supervisors of Montgomery Township shall, from time to time, by resolution, adopt a list of authorized underwriting companies to make inspections and issue certificates regarding electric wiring systems in Montgomery Township. Such designated underwriting companies shall be, and are hereby designated as, the sole persons or entities to make inspections of and issue certificates for electrical wiring and equipment and apparatus and the manner of installation thereof in or on any lot, piece of ground, building or structure or to service any lot, piece of ground, building or structure in Montgomery Township.
