I have a project designing a small chiropractic office which will move their existing X-ray equipment. I have no experience with X-ray equipment. It is an older Universal Easy Matic 300. I can't find anything on the web about this model, but they have told me it is single phase, 240 VAC, 100 A breaker (I'm guessing minimum size breaker). They currently have the machine operating on a 70 A breaker. From reading the code, it looks like I need to specify a 100 A breaker and size the branch circuit conductors for this 100A load. My question is how should I add this in to my total load calculation? I assume I would use this same load since the code specifies this for feeders also, but is there anything special that needs to be done for this type of load? My feed will be from a 120/208 V, 3 phase panel. Thanks for any help I can get!
