Re: use of romex wire in high rise

It depends on if your city code allows you to wire apartments in Romex. Ours don't allow multifamily, 2 or more storied dwelling to be wired in Romex unless they are condos. (1 Apt shares 2 floors.) Sorry I couldn't help.
 
Re: use of romex wire in high rise

Didn't I remember reading somewhere that the 99 NEC had limits along these lines that were dropped in 2002?

If your area hasn't adopted 2002, then I think over the third floor is illegal. But I don't own a '99 NEC...
 
Re: use of romex wire in high rise

the 2002 code article 334.10(2) allows romex as long as the building is types three-four or five construction.

thirty years ago it was allowed for a short period of time in south florida --- i wired two ten story condo buildings ---278 units total and had only two call backs due to "romex". one was a drywall screw through a cable and the other was caused by someone adding a door in their apartment! and i serviced these buildings for three years after they were c.o.ed! i don't see much of a problem with romex -- any wiring method can be dangerous if not installed right!
 
Re: use of romex wire in high rise

I think around here it's three story multifamily. Not NEC though. Fire code or some other NFPA document. It's come up before but I forget what authority it is.

Edit: I'll bet bphgravity Bryan knows.

I think (too lazy to go get the book) IBC prohibits it over 3 stories.

I'd love to hear the rationale behind this rule. :roll:
 
Re: use of romex wire in high rise

The decreased gravity from the three story separation from the crust of the earth results in henotheistic degradation of NM-B under abnormal conditions. A fire is guaranteed if used over the sixth floor, unless the building department has filed the appropriate appeal, stamped, notarized, and signed in triplicate.

George
That sounds very convincing :D .

There are many high rise buildings in the area that I live in that were permitted to use NM cable, and they are all still standing.
Like has been said, any wiring method that is installed incorrectly can be a potential hazard.
I would check your jurisdiction to see what they will permit.
 
Re: use of romex wire in high rise

That's a good point, Al. The barometric phase angle shift in juxtaposition with the henotheistic gradients involved would definutely be resultant from the difference in altitude between the service and the branch circuits in any installation considered. :D
