Re: Electrical
Really?There isn't a commercial building(with exception of a converted residence)that doesn't around these parts.
A 200 amp service 3 phase is average.Sometimes you can luck out and find 400amp service.

Re: Electrical
Single phase is the most common here unless it is a major shopping center. The average small retailer has no need for 3 phase so the developers save the the additional cost. I had 3 phase put in this center because I had plans of eventually putting a salon in it.

Re: Electrical

Re: Electrical
3 phase is also more efficient for HVAC units.
In our new salon we have a buck/booster transformer for the whole panel. It is mounted in the ceiling out of the way. The cost was about half that of individual boosters for each room. |

Re: Electrical
This is just a question for my peace of mind, I'm sure the electrician knows what he's doing. When running the 4 #4 wires is the 4th wire for the ground the same size as the other 3?
