Wiring 3Wire and 4Wire Dryer Plugs
Electrical Question: I have a four wire plug on my dryer.
- I installed a four wire plug in my wall, however, when my house was wired whoever did it cut the red wire off before the circuit panel and hooked up the white and black wires to the breaker instead of the red and black.
- My old dryer had a 3 wire plug so this was not an issue.
- I need to know if I need to find the end of the red wire somehow and pigtail off of that and hook it up where the white wire is now and if so where do I then hook the white wire to in the panel, Or is it possible to rewire the dryer so that I can use a 3 wire plug on it instead
This electrical question came from: Bob, a Homeowner from Kalispell, Montana.
