Hey Iggy,

Simple math says "Yes"....50Hp X 750 watts = 37500 Watts X 1.15 (15%
derate) = 43125 Watts, so your 45000 Watt transformer should do. What
size is the disconnect for the 45KVA fused at??? Needs close to 200
Hey Iggy,

There is no disconnect, only the transformer in the back of my truck.

?????? What ???????? What does that mean, and what does any of this
have to do with your truck?????

KVA is not watts and I am not sure if it is enough to start the
compressor.

You are correct of course. A watt is not a volt-amp. But you only
asked if the 45Kva transformer hooked step-up versus the step-down
mode it was designed for would handle the load of the 50Hp compressor
start-up. So send me the power-factor for the whole set-up I'll do it
again, accurate to one watt.

Take care. Have fun.
