Rated Capacity of Electrical Wire

Safe Amperage Ratings for Electrical Wire: The amperage rating will depend on the insulation type of the #12 AWG wire, Surpassing the amperage rating of any electrical wire is highly dangerous and not safe and can cause the wire to become over heated which could lead to a fire.

The Rating of an Electrical Wire Depends on the Insulation Type
[ad#block]Electrical Question What is the most amperes that a 12awg can hold?
I know they are rated for a 20amp breaker, but can you surpass that safely, and if you can by how much?

This electrical wiring question came from: Bob, a Electrician from Braden
Additional Comments: awesome

Dave’s Reply:
Thanks for your electrical wiring question Bob.

Safe Amperage Ratings for Electrical Wire
Bob, it will depend on the insulation type of the #12 AWG wire, but then again, as an electrician you know that you can look this up in Table 310-16, and the table is provided at the electrical wire link below.
Surpassing the amperage rating of any electrical wire is highly dangerous and not safe and can cause the wire to become over heated which could lead to a fire.

Electrical Tips to Help You Wire it Right

The Safest Way to Test Electrical Devices and Identify Electric Wires!

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 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 Tester
This 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 Cutter
My 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.
This handy tool has multiple uses:
The wire gauges are shown on the side of the tool so you know which slot to use for stripping insulation.
The end of the tool can be used to grip and bend wire which is handy for attaching wire onto the screw terminals of switches and outlets..

The wire stripper will work on both solid and stranded wire. This tool is Very Handy and Easy to Use.
