I seem to recall somewhere in the code that you canput a 31 Amp circuit on a 30 amp breaker. I have a Battery Charger that the name plate rating is 31 Amps @ 240 Volt 1?. Just want to confirm weather to use 30, 35, 40 Amp Breaker.
I'm hard pressed to state it's a Code violation, someone else may know what Article, but I don't know why you would want to. The conductor must be sized to the load and any breaker sized below the load would just be a looking for trouble. If the battery charger operates at full load for 3 hours or more, it would be considered a "continuous load" and your load would be calculated as 39 amps.I seem to recall somewhere in the code that you canput a 31 Amp circuit on a 30 amp breaker.
