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
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
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.
