Hey, I've got a quick question.
I'm installing a small 20" wide range in a commercial building...<6KW.
It's straight 240V and doesn't require a (grounded) neutral .
The electrical service to the building is 240V/3 phase Delta with a center tapped leg supplying the neutral.
It's a GE panel, and one of (the only 2) spaces available in the panel is the high leg (208V to ground).
I'm looking at a GE THQL 2 pole breaker and the breaker specifications list 120V, 120/240V, and 240V.
Is it OK to use this breaker in this application?
Although it's a slash rated breaker, it also has a straight 240V rating (the way that I read it anyway).
I plan on installing a 3 prong receptacle and cord, although there's a 4 wire circuit available that I can use, (I'm finishing someone else's job :-?) The range already has a 4 wire cord attached and the white and green are bonded to the range chassis. :roll:
What do I need to do with the white circuit conductor in the 4 wire cable?
Cut it off..... mark the cable as being fed with a 240 Delta.....or just assume that the next electrician knows that there is chance of making a big mistake if he trys to utilize the white wire (neutral) without doing a little investigation?
This part is strictly from a safety stand point for the next guy.
Anyway, I don't work on this type of service very often, actually very rarely.
Any tips are appreciated.
thanks
steve
