1. • • A standard, dual-element electric water heater typically requires a 240-volt electricity supply. Because electricity supplied to American homes comes in at 120 volts, a special, ‘double leg circuit’ is usually set up for a water heater, so that the two legs make up 120V + 120V = 240V.

   How do you know if a 240 volt water heater is hot?

   • The white circuit wire should be wrapped with black or red electrical tape near the connection at both ends of the circuit (at the water heater and at the breaker box), to indicate that it is a "hot" wire, not a neutral wire. Unlike standard 120-volt circuits, a 240-volt circuit carries live current in both the black and white wires.
