The issue is at a seasonal cottage in ontario. The circuit was installed about 45 years ago.
It is a 240V circuit with a double pole 15 amp breaker.
I measured the current on the two wires at the breaker. One was 14.3 amps and the other was 15.9 amps.
There are two heaters on the circuit and each has its own thermostat.
Why would the two legs of the circuit be so different?
I did run the heaters one at a time and checked current.
On the 14.3 amp side, I measured 5.6 amps and 8.7 amps
and the 15.9 amp side was 6.6 and 9.3.
So each heater/thermostat contributes. Maybe thermostat contacts need a clean?
