Electrical Panel and Circuit Breaker Types
Electrical Question: Why is my 240 volt circuit only showing 120 volts?
I pulled 10/3 wire from my panel to the dryer unit and installed a 30 amp breaker. I’m getting 110 on each leg but get nothing when crossing them. I already replaced breaker and get the same thing.
This electrical wiring question came from: Joe, a Handyman from Tewksbury, Massachusetts.

Thanks for your electrical wiring question Joe.
How to Correct Incorrect Circuit Voltage
There are some electrical panels which do not have a standard configuration which will produce 120 volts instead of 240 volts, this is one of those types of panels, but there is a solution.
Joe, you’ll need to re position the circuit breaker in the panel because you are not attached to separate buses. This has to do with the type of circuit breaker you have and the brand of the electrical panel.
