Can You Use Stranded Wire For Water Heater?

Does water heater wire need to be in conduit?

NO it does not have to be in Conduit… except in maybe ILLINOIS…lol… But it does have to be supported correctly and in a proper connector and so on..

What size breaker do I need for a 4500 watt water heater?

The wiring requirements are less stringent for 3800 watt elements than for 4500 watt elements. A 4500-watt element requires 10/2 wire and a 30 amp (220volt) breaker. The 3800 can be wired with 12/2 wire and a 20 amp breaker.

What size breaker do I need for a 240 volt water heater?

Electric water heaters require a 240-volt dedicated circuit, which serves only the water heater and no other appliances or devices. The circuit wiring typically includes a 30-amp double-pole breaker and 10-2 non-metallic (NM) or MC cable.

How many wires does a water heater need?

On the top or the side of the hot water heater (depending on the type), you will see the junction box cover where the connections will be made. Remove the screw and the cover. Inside you should see two lead wires and a ground screw.

How many amps does a 40 gallon water heater use?

Bottom line, For a 4500w heater w/240v it will draw 4500/240 or 18.75 amps so #10 wire and either 25 or 30 amp breaker, depending on code.

What wire do you use for a water heater?

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.

Is it OK to use stranded wire?

You can use stranded wire anytime you can get it, and your terminations are listed for stranded wire. For instance a backstab (push-in) connector might be listed for ”14 AWG solid” in which case they mean “not stranded”.

Can I use 10 3 wire for a hot water heater?

With a 10/3 conductor. But there’s no neutral connection on the water heater just a ground. In a cable assembly it is still code compliant to re-identify the white as a hot conductor. In conduit you would need to use the proper colors for the hots.

How many amps is 4500 watts?

18.75 ampsIn an electric circuit of 240 volts, 4500 watts is equivalent to 18.75 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 you use 12 2 wire for 220?

If you’re wiring a 220v, 20-amp outlet to run power tools, you can use the same 12-gauge wire you would use for a 110-volt, 20-amp circuit. Remember that the cable must have an extra hot wire. If the appliance draws 30 amps, you need a different type of receptacle, and the cable needs to be 10-gauge.

Can you wire a 10 2 dryer?

If your dryer does not require the neutral, and is a pure 220V appliance, than you can use the 10-2 and be code compliant. The only issue is sharing the neutral and the ground.
