220Volt Wiring
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 California.
James, Thank You for Visiting Ask-the-Electrician!

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 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.
