have customer that is moving to new building and has air compressor that is 240/460 but service is 208y. he wants to install transformer to boost to 240 or 480 the air compressor is 40 amp @ 480. I figured that a 50kva would be needed but the service there is only 200 amp on either panel @ 208v can I use a 20kva and just boost to 240v and be able to use 150amp cb to feed transformer or am I way off
