10 gauge copper wire amp rating
People also ask
How many AMPS is a 10 gauge copper wire?
NEC 10-gauge copper wire has a rating of 30 amps. 10-gauge solid copper wire in general has a resistance of almost exactly 1 ohm per 1000 feet. The rating is limited by how much heat the insulation was designed to withstand. NEC 60/75/90 deg C rated insulated wire is rated for 30/35/40 amps respectfully. Click to see full answer
What is a 10 gauge wire rated for?
Likewise, what is 10 gauge wire rated for? If you are simply talking about a typical 10 gauge cable used in building wiring, the National Electrical Code limits 10AWG wire to 30A for most applications. This figure is necessarily a conservative rating for safety under most typical situations.
What is the current rating of a copper wire?
