Adding a New Circuit to the Main Panel for a Garage Panel
Mike in Florida asks: I have the electrical main coming into an exterior panel, and being back-fed into a 125 AMP breaker. This then flows through the panel itself and into a sub-panel just inside the building.
Adding a Breaker for a Garage Panel
Electrical Question: Can I use the main panel’s unused circuit breaker slots to install a breaker for a sub-panel?
I have the electrical main coming into an exterior panel, and being back-fed into a 125 AMP breaker. This then flows through the panel itself and into a sub-panel just inside the building. In the main panel the neutral and ground is wired to the same bus bar. The sub-panel is fed from this main panel and also has a 125 AMP breaker. My sub-panel is full but I need to pull 240V from somewhere. Can I use the main panel’s unused slots of which there are 6 knock-outs remaining?
This electrical wiring question came from Mike, a Homeowner in Orlando , Florida.
Additional Comments: It is handy to be able to actually ask an electrician something!
Thanks for your electrical wiring question Mike.

The Safest Way to Test Electrical Devices and Identify Electric Wiring!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, [amazon.com], I use for the detection of Standard 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.
