Here is something from another code, that all of New York State is supposed to be following.

In the NEC, section 250.118 Types of Equipment Grounding Conductors.
(1) States that Aluminum conductors are permitted for equipment grounding purposes.

Here is where I need help:

The Residential Code of New York State has changed the wording here and I would like to know how you think this affects the installations in New York State.

From the NYS Residential Code:
E3808.8 Types of equipment grounding conductors.
1. A copper or other corrosion-resistant conductor.

The wording in the NYS Residential code is ALMOST identical as the NEC, except it does not include Aluminum conductors as does the NEC. The verbiage of Aluminum was purposely removed. IMO this has eliminated Aluminum for use as an EGC.. If we read 250.64(A) in the NEC, that says to me that Aluminum is not permitted in corrosive areas, therefore is not a corrision-resistant conductor.

I know that without the copy of the NY Code, it is hard to help, but any ideas here are appreciated.


I have spoken to a representative of NYS and he said that most people do not use Aluminum anyway. I asked him what about all of the supply houses that stock Aluminum SER cable for feeders in dwellings and he had nothing to say.

Pierre,

The Residential Code of NYS is based on the 2000 IRC and references the 1999 NEC, not the 2002. The wording in 250-118(1) ('99 NEC) reads the same way as the E3808.8 in the NY code.

I know that doesn't really help, but it shows that NY didn't purposely remove Aluminum from the wording.

Thank you for picking that up. Now I am a little more confused than before. I will put a little more time in the 'saddle' to see what it might mean.
Thanks again

Pierre
