Battery Charger - Pump - 20A circuit
2 questions:
I have a 10A battery charger for 12V DC battery on the same circuit as a 1/2 hp sump pump. I cant find the rating on the charger. Generally whats the total amperage here, can they share a circuit?
Battery charger gets quite warm when charging... are battery chargers supposed to get warm?

If the battery charger was 100% efficient it would be 12v x 10A = 120watts / 120v = 1A
I'd figure on 2A max. for the battery charger.
The transformer heats some and there is a diode or rectifier mounted to the case
to convert AC to DC and that runs warm. Perfectly normal.
