I was just offered an electrical plan to bid, will go look at the job after the 4th.
It looks to be a coffee shop, the service items needed to make it work, must already have lights and signs and emergency lighting, as none of that is indicated in the plan.
Am to add a 3ph 200a 42 space panel protected by a 100a breaker on a main panel.
What is a nuisance is that I cannot make out from the drawing if this is a delta arrangement with a wild leg or a balanced Y.
And it looks to be all about the draftsman just doing a cut and paste. The panel is called out as 120/240v, and there are several references to "high phase do not use" on the B phase, yet elsewhere on the schedule of circuits that phase is clearly being used to create 208. with either A or C phase.
And there is a three phase 208v water heater specified.
I'd ask the General what the deal is, but then I'd need to explain delta and Y to him, and he gets testy when I do that.
I'll be making a point of taking a meter with me to the walk thru! Could easily be that they have one and think they have the other. Scary, actually.
