Installing 220Volt Wiring for a Solar Power Monitor
James in California asks: Is it code compliant to run two separate 12-2 Romex cables instead of one 12-3 for 220volt?
Electrical Question: Is it code compliant to run two separate 12-2 Romex cables instead of one 12-3 for 220volt?
Is it code compliant to run two separate 12 2 Romex instead of one 12 3 for 220. It’s only a 3 foot run and I do not have any 12-3. This is for a Sun Power solar panel monitor, which requires a 15amp 220volt circuit.
This electrical wiring question came from James, a Homeowner in Rocklin, California.

Reviewing the Electrical Question:
- Is it code compliant to run two separate 12-2 Romex instead of one 12-3 for 220volt. It is only a 3 foot run and I do not have any 12-3 wire.
- James, from the information you have provided, I can tell that you may not understand a few things about the required circuit, so lets take a look at this. First of all, a 220volt circuit typically does not need a neutral wire, only two power conductors and a ground wire. Next, a 15 amp circuit does not require a 12 gauge copper wire. A 14 gauge copper wire is rated for 15amps. Based upon this a 14-2 with ground should be sufficient.

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.
