Hi everyone
Doing a project where we are renovating part of a building do be a shop. The current service is 240-3 open delta. The local POCO will not allow (and for good reasons) to run our 50HP air compressor on an open delta service. They said they are going to bring 208-3 phase to our building instead.
My suggestion was to do a ADDITIONAL service to run our new shop equipment, and keep the open delta service to serve the existing loads that way we wouldn't have to be worried about overloading the existing service when we add on.
The gentleman at the POCO is suggesting (as well as the electrical contractor) that we bring in the new service and run EVERYTHING with the new 208-3 service.
Because this is an existing building however, my main concern is that some of the breakers will now be overloaded because the voltage is 208 now rather then 240. I see this as a legitimate concern, however everyone else seems to think differently, am I over-thinking this?
Thanks
