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.
James, Thank You for Visiting Ask-the-Electrician!
Thanks for your electrical wiring question James.

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.
