ECN Forum Forums General Topics of the Trade General Discussion Area 3 wire vs. 4 wire after service disconnect?

Nice point made there!


Often over-looked items....

trekkie76,

250.32(D) only applies when exceptions 1 or 2 of 225.32 are met (the 225.31 in some printings of the NEC is a misprint - see the errata). Those exceptions will not apply to the situation you describe, so 250.32(D) will not come into play. In addition to the main disconnect at the pole, 225.32 will require a disconnecting means located at the house.

Thanks e57.

225-32 refers to placement of the disconnecting means on the premise. those exceptions don't nessasarly have to be applied. So, 250-32d says that as long as the placement(location)of the disconnect conforms to 225-32, the following conditions shall be met:
1. the connection of the grounded conductor to the grounding electrode at the seperate building shall NOT be made.
2. An equipment grounding conductor for grounding any non-current carrying ewuipment shall be run with the circuit conductors, and bonded to the grounding electrode.
3. the bonding shall be done in a panelboard, j- box.
With the service disconnect on the pole(1st building) feeding the house( 2nd building), the disconnect is outside the buildings, satisfying 225-32, wouldn't this situation be called" disconnecting means located in Seperate Building or structure on the same premises" ?
