I have two mammogram machines that are rated at 35 amps, 208V, 1 phase each. I need to pull power from an existing 480/277V 3 phase panel. (The existing 208/120V 3 phase panel is full) I was thinking on providing a 30KVA 480-208/120V single phase transformer to power the two 35 amp, 208V 1 phase mammogram machines. Sorry if this is a dumb question but would I provide a 3P50A breaker on the primary side if it's a single phase transformer?
I need to split the secondary side to feed each mammogram machine that is located in two seperate rooms. I was planning on providing a gutter in the electrical room where I am putting the single phase transformer and then providing two 2P35A enclosed breakers and then run the feeder to the 2P35A shunt breaker (required by the manufacturer) which will be located in each mammo room. Does this sound right?
