Short term step up
Short term step up
(OP)
Our shop has 240 3 ph 60 Hz, and we need to run a short term (several 5 minute tests) on some equipment needing 480 3 ph.
We have a disconnected distribution transformer, 480 Y / 240 delta 150 A secondary, which is at least 30 times the ampacity needed for the test.
Is it OK to backfeed 240 into this to obtain the 480??
Thanks in advance!
