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.

The Safest Way to Test Electrical Devices and Identify Electric Wires!The Non-Contact Electrical TesterThis 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 TesterThis 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 CutterMy 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.

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,
