I have a job where the engineer is calling for a 37.5KVA transformer: primary 480VAC, stepping down to 120/240v to power up a portable office trailer. I believe the office trailers drawings only about 30 amps max.
It's calling out for a 2-pole, 175A, 480VAC, 65KAIC in the main panel to the transformer. Isn't this too high an amperage. Are there any safety issues?
