Often asked: What Size Wire Do I Need For A 4500 Watt Water Heater?

How many amps does a 4500 watt water heater draw?

A typical 50 gallon electric water heater runs at 4500 watts. In an electric circuit of 240 volts, 4500 watts is equivalent to 18.75 amps.

What size wire do I need for a 5500 watt water heater?

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. So, 5500 watts / 220 volts X 0.80 = 20 amps.

How many amps is 4500 watts at 220 volts?

A 4500 watt element draws 18.75 amps at 240 volts. Code requires wire sized at 125% of continuous load. 18.75 x 1.25= 23.5 Amps.

Can you use 12 2 wire for a water heater?

A 12-2 w/ground should be enough, although I would use a 10/2 for future “upgradability”. 10/2 is the standard cable for a water heater. Connect white to red. 12/2 would be insufficient for almost all water heaters.

Can I use a 40 amp breaker for water heater?

You cannot put a 40A breaker on #10 wire. If you are sure there is (at least) #8 wire all the way from the breaker to the water heater, you can just replace the 30A breaker with a 40A breaker, but if and only if you have verified the size of the wire throughout the entire circuit.

Can I replace a 4500 Watt water heater with a 5500 Watt?

Can I replace 4500 watt elements with 5500 watt? You can definitely replace 4500 watt with 5500 watt and get 4-7 gallons more hot water from a tank.

What wire do I use 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.

Does wattage matter on a water heater?

The differences in wattage is not important but the higher wattage elements will heat the water faster. Most water heater connections are 30A. That would safely power up to a 24A continuous load.

What size breaker do I need for 4500 watts?

30 Amp dual pole breaker and 10 Gage wire size are required for 4500 watt elements.

Can I replace a 3800 Watt water heater with a 4500 Watt?

You can buy 3800 watt elements to replace the 4500 watt units. This is commonly done when the electric is NOT 10 gauge wire with 30 amp breaker.

Requires 240 volt electricity (a 30 amp breaker, with 10 gauge wire from the panel). Also available in a BC compliant model. Performance 60 Gal Electric Water Heater with 6 Year Warranty is rated 3.5 out of 5 by 6.

How many wires does a water heater need?

You now have an redundancy with the ground and the white wire. The white wire is not needed. The long and the short of this story is that a water heater needs two hot conductors and a ground to work.

Can you use stranded wire for water heater?

Use only 600 volt solid copper wire. Do not use stranded wire or extension cord. Do not use solder anywhere on residential 120-240 volt wiring.
