Re: Residential generator systems
Along these lines, when looking in NEC 2005 702.7, I find:
Code:
702.7 Signals. Audible and visual signal devices shall be provided, where practicable, for the following purposes.
(1) Derangement. To indicate derangement of the optional standby source.
(2) Carrying Load. To indicate that the optional standby source is carrying load.
Exception: Signals shall not be required for portable standby power sources.
I had this question for NEC 2002, but it seemed more restrictive and I gave up on the idea. NEC 2005 seems to have lightened up a little bit on this.
My question: Can I install a 4-gang box full of three ways to serve as a BC TS for a generator? I saw a $210 BC TS that essentially did nothing more than this, but had a pilot light over each switch to show the generator was on for that circuit. The $210 option didn't meet my interpretation of the "Derangement" and "Carrying Load" requirements of 2002, in my opinion.
Now they have added this Exception, so now my three-way hootenany will be code acceptable, right? As long as I can drag my generator around?
