Current transformer on a meter

[electrobuzz]

Is it required to use a current transformer for a 400A meter?

That is a question for your utility. I have seen both self-contained and CT meters for 400 services.

PG&E required CT's for 400A service.

You need to check to see if your utility has K base meters. If so, buy a K base socket.

To answer your question, yes if they don't have K base meters. No if they do have them.
