I'm wiring approximately 30 feet of wire 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 - or what is the application? 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. This page has a chart showing wire sizes and amperages which should be helpful as well: http://www.ask-the-electrician.com/electrical-wire.html
Be Careful and Be Safe - Never Work on Energized Circuits! From: Mike C Dave I'm wiring in a over the stove microwave approximately 12 amp required. Thanks Mike
Mike, Install a 20 amp circuit for the microwave. The wire should be a 12/2 Romex Type-NM with ground. Dave

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.
