S9 220V Electric

Hi guys,
If I have 3 S9s connected to a 15x2amp Circuit Breaker (220v). How many amps should I get per line (2)?

Thanks,

I measured 6.25 amps per S9 @245V.

NFPA rules limit continuous loads to 80% of the circuit rating. So a 15A circuit is limited to 12A.
I use 20A circuits to feed 2 S9s.

When I put the clamp on each line it gives me 18amp, but there are 2 lines so 18 amp on each = 36 to a circuit of 30(220). Why do I get 18 on each line? Isn't it supposed to be 9 amp on each line (2) to get 18 amp?

Nope. All the current flows through both lines.

Measure current of one line X Voltage = Watts

The current on the other line should be exactly equal. If not, some current is going to neutral or ground from one of the lines.

Thanks for your help!
