What is allowable ampacity?
Ampacity is defined as the maximum current, in amperes, that a conductor can carry continuously under the conditions of use without exceeding its temperature rating. Get the value of the thermal resistance (RDA) between the conductor and the ambient air or soil. …

Is 8 Thhn good for 50 amps?
THHN uses the 75 deg C column in figuring ampacity in newer work. #8 is rated right at 50 amps in that column.
What is 8 gauge Thhn rated for?
55 AMPS
What size wire do you use with a 50 amp breaker?
6
Can you run a 60 amp sub panel off 100 amp main?
You can feed a 100 Amp panel with a 60 Amp breaker. Keep in mind that the sub panel needs to be rated above the breaker size.
Can 6-gauge wire handle 60 amps?
Electrical wire manufacturers publish charts recommending the maximum current for each wire gauge. According to most of these charts, 6-gauge wire is suitable for 55 amps, which means that, technically, you should jump to the next gauge for a 60-amp circuit.
