1000 amp 120/240 single phase service

[electrofelon]

Are you working under the 2020 NEC? If so, are you having to deal with 230.46?

Sounds like he will be utilizing feeder taps and not have to tap service conductors.

1200 amp single phase service I installed about 35 years ago. Three phase was an available, but customer did not want to pony up the money for it, and the poco kw rate for single phase was much cheaper.

the poco kw rate for single phase was much cheaper.

I never understood that reasoning

 

[hillbilly1]

The poco paralleled two sets of 350 quadraplex. The house next door is also off this transformer.

The warehouse down the road that he bought later had an open delta three phase service. He had it changed to single phase too, to get the cheaper rate. It was previously a sewing plant, but all he needed was lights.

Yeah I have open Delta 4 wire at my shop/home. When I bought the place in 2015 the commercial rate was actually cheaper, not sure what it is now, I'm afraid to look. Transmission + Distribution charge can get a bit high though if I run something big

energy charge shouldn't really change, I can see different base charges depending on equipment needed to deliver the service. But at same time how much does it cost them to have a 75 kVA single phase pot on a pole vs three 25's? The 25's are probably one the most common pots they keep in the warehouse as well.

POCO by me only supplies up to 400 amp--120/240 1 phase. I would look at 3 phase to the building 208/120 Y.
As others have stated, use the 6 disconnect rule with your panels. No 1000amp disconnect. Way too much $$$

As the OP said in #1-

The power company only has 120/240 single phase to that area

A lot of discussion has strayed away from that.

The op asked about delta in post #17:

So power company now says 1000amp single phase is to hard to get a transformer for. Has anyone had any work with 120/240 3 phase?
