What size Thhn wire is good for 100 amps?
When it comes to the lines connecting master and secondary panels, where the line will carry as much as a full 100 amps, use a 2-gauge non-metallic sheathed electrical cable. The cable must contain one or two hot wires depending on your needs, one neutral wire, and one ground wire. Each wire should be 2-gauge in size.
Will 10 Thhn carry 30 amps?
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].”

How Far Will #10 wire carry 30 amps?
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.
Is 8 Thhn good for 50 amps?
No not safe to use a 50 amp breaker. The only time a 50 amp would be ok with #8 woul be if these were individual thhn wires in conduit. If the stove specifically calls for a 50 amp breaker the wire does need to be replaced in order to use a 50 amp breaker.
Is ampacity the same as amperage?
is that amperage is the electric current’s strength carried by a conductor or machine generated as measured in amperes while ampacity is the root mean square of the electrical current which a device (usually a wire) can carry within a specific environment (including temperature rating, power loss, heat dissipation, etc …
What is the ampacity of a No 3 0 Thhn copper wire?
