What wire size do I need to go 100 feet for a 60 amp service to a workshop?
If the circuit is 100 amp or less you have to size the conductors based on the 60-degree celsius column unless the breaker and the equipment terminations are rated for 75 or 90 degrees. You have to use a #4 conductor to feed a 60 amp circuit.
Will 10 gauge wire carry 50 amps?
A 10 gauge wire can handle 50 amps bare copper like a power line but most insulated wire is rated by NEC at 35 amps max with a 30 amp circuit the normal use for 10 gauge. The short answer is yes, but only for very short periods of time such as motor starting inrush.
How much amperage can a 10 wire carry?
RULES OF THUMB. Many techs will repeat these rules of thumb and rely on them in all circumstances: “Twelve-gauge wire is good for 20 amps, 10-gauge wire is good for 30 amps, 8-gauge is good for 40 amps, and 6-gauge is good for 55 amps,” and “The circuit breaker or fuse is always sized to protect the conductor [wire].”
