Wiring a Dryer Outlet
Electrical Question: I need help wiring a 240volt outlet for a dryer.
- Dryer Outlet Wiring Project
- I have dedicated line with a double pole 30Amp breaker I want to use for a dryer.
- The line was not in use and does not have an outlet, it is a 3 wire line, white,black and bare copper wire.
- I bought a 3 prong 240Volt outlet.The instructions say to hook up the white wire to the L shaped prong and the two hot wires to the 45 degree prongs.
- I tested the lines with a multimeter and the voltage between the white and bare copper wire is 120v, 120v between the black and cooper and 240v between the white and black.
- The two hot wires are the white and black and the bare copper wire is the neutral?
- Should the outlet be hooked up with the copper wire to the L shaped prong and the white and black to the 45 degree hot prongs?
This electrical question came from: Joe, a Homeowner from Texas.
Thanks for your electrical question Joe.
