Trying to size a service for a chiropactors office and not sure on the demand for an X-Ray machine. The X-Ray Tech say's he needs an 100 Amp 220V circuit. Here's what I have existing:
100 Amp 3 Phase Service w/ 1 Alum Conductors
So do I figure the X-Ray machine at 100% demand?
And my load calcs would be:
12 receptacles @ 180VA = 2160
640sq.ft. @ 3 VA = 1920
Heat @ 10,000 VA
Sign Ckt. @ 1200 VA
X-Ray Machine @ 24,000VA
Total 39,280 VA
39,280VA / 240V = 163.66 Amps / 1.73 = 94.60 Amps
Correct? The 100 Amp service should be suffecient?
Thanks !!!
