If you look in the code book, 12 AWG wire is legal to 30 amps if you can run it at 90 degrees C.

Can you use 12 gauge wire for water heater?

Common Current and Wire Gauge Sizes Wire a hot water heater with wire that’s sized to accommodate the heater’s current requirement. For example, a 20-amp hot water heater needs 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.

Can I use 12 2 wire for hot water tank?

Most electric water heaters installed in North America require a 30-ampere grounded 240-volt connection which requires a pair #10 copper wires PLUS a ground wire. Copper 12/2 wire is rated for a maximum of just 20-amperes and would be inadequate both in current capacity and for lacking a ground wire.

What size wire do I need for 30 amps?

10
For a maximum of 30 amps, you’ll need a wire gauge of 10. The most common household item that requires a 30 amp circuit is a central air conditioner.

What size breaker do I need for a 30 gallon water heater?

The branch circuit needs to be calculated at 125\% of the rated ampacity for this type of water heater to be considered a continuous load. In order to work on a 20 Amp OCPD, you will need a 25 or 30 Amp circuit.

What size breaker do I need for a water heater?

Electric water heaters require a dedicated 240-volt dedicated 30-amp circuit and a 10-2 non-metallic (NM) or MC cable. This means the breaker only powers the water heater and no other appliances. A 30-amp circuit breaker can power all 4500watt water heaters regardless of gallon size.
