apartment meters?

[mayjong]

i have a house, broken up into 4 apts (legally)
a tenant claims that some of her circuits feed a different unit... besides the question of who pays the bill,(and correctly labeling the panel) is this illegal per the nec('05)?
thanks...

No, see 210.25

 

[mayjong]

so, no branch circuits from a unit to the common area, but it is o-k to use 1 panel for two units?? :-?

AFAIK, yes, but you're going to have trouble divvying up the power bill that way. Plus, both tenants must have access to it.

It is a violation of 210.25. Read the first sentence: "Branch circuits in dwelling units shall supply only loads within that dwelling unit, or loads associated only with that dwelling unit."
To extend the circuit to another dwelling unit would violate this first sentence. :smile:

Ignoring that it would be impractical from a billing POV...

Would this apply if the Panel is not in the dwelling unit, but in a common area or on the exterior? Obviously individual branch circuits would not be allowed to split across dwellings, but what about multiple branch circuits from one panel separately feeding multiple dwellings?

I can't remember a time that it was permissible to extend circuits from one dwelling unit to another. The fact that it's been done for many years has sure made a mess of billing.

The provision talks about "loads" not locations. A panelboard in a general, common area, would have to comply with other areas of the code, including but not necessarily limited to fire resistance ratings if mounted in a wall requiring same, and access to ocpd's by occupants. Only "loads" associated with the individual dwelling unit would be able to serve such unit.

Here, you may be talking about "feeders" originating within a service panel and feeding individual tenant panelboards which then have their respective branch circuits serving only loads within those respective units. This would be permissible. :smile:

If her circuits are branch circuits coming from her panelboard, and extending into other units, this is a violation of 210.25. :smile:

sorry, the sub panel is in a common area. some conductors go to unit #3 , and some conductors go to unit #4. the tenant of #3 is getting the bill, and doesn't appreciate paying the bill. wants us to do something about it, and i'm not sure i can, even using 210.25 , i don't think it applies...
