[QUOTE="Tim McCulloch, post: 57373, member: 67"] Re: Single and Three Phase power conection questions? IIRC the minimum AWG for single conductor feeder is #2. It's a Code thing. Ah, found it in my 2005 NEC - 520.53(H)(2) "Single-Conductor Cables. Single-conductor portable supply cable sets shall not be smaller than 2 AWG conductors. The equipment grounding conductor shall not be smaller than 6 AWG conductor." You need to read beginning with Section IV,"Portable Switchboards on Stage" from Article 520.50 . Stop reading when they get to Dressing Rooms. You'll learn some lampie stuff, sorry... ;) Then get thee hither to Article 525. Read it all, it's short. Then on to 640. In all of the Articles you'll be referred to things in 200 and 300, and some 400. You'll need to read them and glean what is applicable to us. Also note that 520 and 525 have additional requirements to (or a few exceptions to) what is in 200/300/400. Then sit back and think about it all. The meat is in 520.53. [/QUOTE]
