The Correct Wire Size for a Microwave Circuit

I'm wiring approximately 30 feet of wire for a circuit underneath my house .

Should I use 12-2 or 10-3 due to the length.

Hi Mike - Great Electrical Repair Question!
Mike, 30 feet is not a distance to be concerned about as it applies to voltage drop, what you need to pay attention to is what the circuit is to be used for, in other words, or what is the application for the new circuit?

For example: general purpose lighting and/or outlets can be wired with 12-2 Romex placed on a 20 amp circuit breaker, or 14-2 Romex placed on a 15 amp circuit breaker. On the website is a chart showing wire sizes and amperages which should be helpful as well on the electrical wire page.

This chart will provide the information you need to select your wire size.

I'm wiring for a microwave oven which pulls approximately 12 amps.
Thanks Mike.

Hi Mike,
A 20 amp circuit using 12/2 romex would do just fine.
Don't forget to get a permit and an inspection!
For best results hire an electrical contractor.
