Readers ask: What Wire For Hot Water Heater?

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

All you need is 2 insulated conductors and 1 ground conductor. Since you have already bought 10-3 cable, I would just cap off the white conductor at both ends and use the red and black conductors for your hot wires and the ground conductor to attach to the green screw on the water heater.

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 10-2 wire for a water heater?

Most water heaters are wired with 10-2 w/Ground shielded cable. For long distances you may need to go with heavier wire. When you use this type of wire both the white and the black will serve as hot conductors. The bare ground wire will also be connected to the neutral lug.

Can you use 12 2 wire for 220?

The same 12-gauge wire can be used for a 220v, 20-amp outlet to run power tools. You need a different type of receptacle and 10-gauge cable if the appliance draws 30 Amps.

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.

How many amps does a 60 gallon water heater use?
