I just installed a brand new ADX-60 rotary phase converter in my new shop.
The documentation for the ADX-60 claims that idle amperage draw should be approx 7.45A.
My clamp meter is showing a 36 amp draw on idle. No loads hooked up.
Now all wiring is per the manual and correct according to American Rotary, all wire sizing exceeds requirements in installation guide and NEC requirements.
When talking to American Rotary I was just told that it is normal and to just run it.
I would like help understanding this. Is this normal? If so why do they claim 7.5 A idle? If not what might be going wrong? Someone else told me it my be due to the way the RPC works, regenerative power flowing back and and forth measuring 36amps total. This would obviously be impossible to measure with a clamp meter or normal multimeter. Anyone else have a RPC they can clamp a meter on during idle?
Btw this is my first post on practicalmachinist, been a lurker for a long time. Let me know if I am breaking posting protocol or something.
Thanks for the help !
