Does a tankless water heater require a dedicated circuit?
A tankless water heater will require a dedicated circuit as specified by the installation manual of the unit that has been selected. If you need additional space in the panel for the circuit breaker then a quad circuit breaker may be allowed as specified by the make and model of the panel.
What gauge wire is needed for a tankless water heater?
You must utilize either a 120- or 240-volt circuit, wholly devoted to the heater. Both voltages require 8-gauge wire, and the section exposed to the area under the sink must be armored cable.
What wire do I use for an electric water heater?
It’s a good idea to wire a hot water heater with wire that’s larger than the current requirement. A 20-amp hot water heater requires 12-gauge wire, a 25-amp hot water heater requires 10-gauge wire, and a 30- to 40-amp hot water heater requires 8-gauge wire.
Which wire is the hot wire on hot water heater?
Take the white wire (“hot” line) and wrap electrical tape over its insulation (this is for identification purposes). Do this at the breaker panel, too. Then connect the white wire with the other wire within the water heater.
What size breaker is needed for tankless water heater?
A gas tankless water heater only needs a 15-amp, 120 volt dedicated single-pole breaker for this purpose.
Do you need a GFCI breaker for a tankless water heater?
Most tankless water heaters are placed outdoors. The attachment plug serves as the disconnect and the receptacle shall be protected by GFCI. If there’s a new circuit that serves only exterior receptacles, no AFCI is required. If the receptacle is added to a circuit, there’s most likely a requirement for AFCI.
What size breaker do you need for a tankless water heater?
Can I use 10 2 wire for a water heater?
Electrical wires Since the generic breaker size for water heaters is 30-amps, the best wire size is a #10 American Wiring Gauge (AWG). I suggest you use a 10-2 Non-Metallic Cable (NMC) for a 30-amp 240Volt circuit. This type of wire consists of two conductors with a ground— a total of three wires.
Does a tankless water heater need its own circuit?
