Laundry Room and Dryer Electrical Wiring


By Dave Rongey - Summary:

Wiring a Laundry Room – See if your panel will provide the right power for your clothes dryer circuit. Electric dryer installation with a typical 220 Volt electric power cord.

Laundry Room Electrical Wiring

Electrical Question: My main panel has a double pole 125 amp as its main breaker.
On the main there is a 70 A breaker that is service for a sub panel in what we call the pool house.
Recently I built a laundry area in this house adding a 30A breaker for the dryer.
The problem is the dryer wont work. So I opened the sub panel where there is a 100 Amp main it.

Could this be why my electric dryer does not work?
I should also say, there is an Heating and Air Conditioning unit that has its own 30Amp circuit breaker. Sometimes the unit is slow to start like its not getting enough power.

Additional Comments: what Ive seen so far….awesome website.

John, from the information that you have provided, I would strongly suggest that you contact a Licensed Electrical Contractor to come out and review the work that has already been done, paying attention to the main electrical panel and the service to the additional sub-panel. I believe this will be in your best interest and for the safety of the project electrical wiring.

    Electrical Wire for a Dryer
    Hi Robert,
    Typically #10 copper is used for wiring a 240 volt electric dryer circuit.
    One example of a new dryer circuit would be 10/3 with ground Type NM Cable.

    I hope this helps,
    Dave
