Service Up

The op appears to be in upper n.j. which is pse&g area.
He says he never did a 3 - p service and i don't think he is sure how he is
going to hook up to the cts at all. Maybe he should put in a seperate service
and be safe. Puck if I knew how I 'D put in my 2 cent. GOOD LUCK
call your inspection dept -call afriend

Cts

Cts

i do know that you shouldn't disconnect the CT from its load while the primary is powered up, or very high voltages are created.

This is why they are shipped with shorting bars in them. The short circuit current is inherently limmited by coil resistance/reactance however the open circuit voltage can be very high with a heavy load running through the CT aka CURRENT TRANSFORMER

caution!!! Read art.230 Are the services the same voltage? Check ahj
