I have a single phase 240v service rated at 600 amps that I would usually use a 4s meter and socket for. Unfortunately, my socket is back ordered for 6 months. Is there a 3 phase meter form and socket I could use as an alternative?

I should have explained the service better. It is a 3 wire 120-240v single phase service. Is a 3S still possible? I know on a 4S I would have my voltage and current coils matched up for the meter. Could I use a 9S (usually a 4WY in our system) and wire it to measure both of the 2 phases with the voltage and current coils matched up?

A 9S would meter correctly wire as normal.
A 3S would also work. 3S simply uses one CT rather than two.
Talk to the POCO, see what they will accept
