Electric Clothes Dryer Double Pole Circuit

How an Electrical Circuit is Wired for an Electric Clothes Dryer


How an Electrical Circuit is Wired for an Electric Clothes Dryer
Electrical Question: I bought a new electric clothes dryer. Everyone says I must have a 30 amp circuit breaker. My old dryer has been running on a 20 amp double pole circuit breaker with 10 gauge wire. Do I need to replace the breaker with a 30 amp? And why the heck did the old dryer run all these years on the 20 amp double pole circuit breaker!
Thank you,
Charlotte

Electrical Tips to Help You Wire it Right

The Safest Way to Test Electrical Devices and Identify Electric Wires!

The Non-Contact Electrical Tester
This is a testing tool that I have had in my personal electrical tool pouch for years, and is the first test tool I grab to help identify electrical wiring. It is a Non-contact tester that I use to easily Detect Voltage in Cables, Cords, Circuit Breakers, Lighting Fixtures, Switches, Outlets and Wires. Simply insert the end of the tester into an outlet, lamp socket, or hold the end of the tester against the wire you wish to test. Very handy and easy to use.

The Quickest Way to Check for Faulty Electrical Wiring!

The Plug-In Outlet Tester
This is the first tool I grab to troubleshoot a problem with outlet circuit wiring. This popular tester is also used by most inspectors to test for power and check the polarity of circuit wiring.
It detects probable improper wiring conditions in standard 110-125 VAC outlets Provides 6 probable wiring conditions that are quick and easy to read for ultimate efficiency Lights indicate if wiring is correct and indicator light chart is included Tests standard 3-wire outlets UL Listed Light indicates if wiring is incorrect Very handy and easy to use.

Strip Off Wire Insulation without Nicking and Damaging the Electric Wire!

The Wire Stripper and Wire Cutter
My absolute favorite wire stripping tool that I have had in my personal electrical tool pouch for years, and this is the tool I use to safely strip electrical wires.
This handy tool has multiple uses:
The wire gauges are shown on the side of the tool so you know which slot to use for stripping insulation.
The end of the tool can be used to grip and bend wire which is handy for attaching wire onto the screw terminals of switches and outlets..

The wire stripper will work on both solid and stranded wire. This tool is Very Handy and Easy to Use.

    Electric Dryer Stopped Working
    My electric dryer stopped working, bought new one it doesn’t work. The circuit breaker box has a 30 amp double pole circuit, one wire was 115volts reading and the other was 86volts. I called the landlord who said his son will be out to switch the wires down to the pool pump breaker. I believe it’s a double pole 20 amp is this safe and OK?

    • Dave Rongey says:

      Fault with Dryer Circuit Breaker
      Hi Johnny,
      From what you have described the electric dryer circuit breaker either needs to be reset, the breaker is faulty, or the connection of the circuit breaker and the panel is at fault.
      The landlord should be advised that placing the dryer circuit onto the double pole 20amp pool circuit breaker will most likely cause the breaker to trip off. The solution is to identify the problem with the dryer circuit breaker and make the proper repairs.
      A qualified electrician is always the best person to perform this type of work.
      Be Safe,
      Dave
