Installing a Dryer Circuit and Breaker


By Dave Rongey - Summary:

How a Quad Electrical Circuit Breaker Could Be Used – In this case, the 2-pole may be replaced by a quad 30 amp circuit breaker which will provide the 240 volt circuit for the electric dryer. The circuit wiring configuration is critical and must be done correctly in order for both of the circuits to work correctly, and of course, the quad circuit breaker must be available for that particular make and model electrical panel.


Options When Installing a Dryer Circuit and Breaker

Electrical Question: I have a 100 amp panel at home with no more room for circuit breakers. I got a new electric dryer and I wanted to get a sub panel to feed it.

I was going to remove a 30amp 2 pole breaker that’s feeding 3- 240V heaters and feed the heaters from the sub-panel as well. What size sub-panel could I use and wire sizes please.

This electrical question came from: Jose, a Student from Reading , Pennsylvania.

Thanks for your electrical question Jose.

Jose, save your money, you may not need to install a new sub-panel! In most cases, and with newer electrical service panels, there are quad circuit breaker that can be used to create two 2-pole 240 volt circuits in the same place as one 2-pole 240 volt circuits.

How a Quad Electrical Circuit Breaker Could Be Used

Skill Level: Intermediate to Advanced.
Tools Required: Basic Electricians Pouch Hand Tools, electric drill,  auger bits and extension cord.
Estimated Time: Depends on personal level experience, ability to work with tools and install electrical circuit wiring.
Precaution: Identify the panel circuit, turn it OFF and Tag it with a Note before working with the wiring.
Notice: Installing additional circuit wiring should be done with a permit and be inspected.

In the case of this question, the 2-pole may be replaced by a quad 30 amp circuit breaker which will provide the 240 volt circuit for the electric dryer. The circuit wiring configuration is critical and must be done correctly in order for both of the circuits to work correctly, and of course, the quad circuit breaker must be available for that particular make and model electrical panel.

As always, I recommend that a qualified electrical contractor be called to perform any electrical panel work.
