was wondering if you could help me a little.
I have 3 homework questions that I'm not sure of the answers and wondering if you could assist me.
1. When a series rated system is installed you must _________________.
2. What type of lighting is prohibited in residential wiring?__________________.
3.What is the minimum size neutral conductor that can be taped at it's termination for identifying means? _____________.
The answer I had for question 3 was #4AWG, per 200.6(B).
For the series rating, the best I could come up with was "shall be field marked with the specifics of the series ratings and must be an engineered or tested system" . . and yes, that's exactly how the question is worded.
As for the residential lighting, I've read and re-read 210.6(A), and the only thing I can find is that it says "voltage shall not exceed 120 volts between conductors that supply the terminals of the following: (1) luminaires (lighting fixtures)"
I did call an electrical supply company and the salesman told me that 277 volt lighting is not for residential/dwelling units. So, it kind of confirms my thoughts. I'm looking for verification, though.
As for the homework . . .just like in the "real world" we are encouraged to obtain information however necessary. My instructor (who is a building inspector professionally) turned us on the the Mike Holt website and forum.
Thanks again for responding.
