How many amps can 12 gauge wire handle at 120 volts?
A 12 gage wire (AWG, American wire gage, copper wire) is rated at 16 amps constant load at either 120 volts or 240 volts.
Can 6 gauge wire handle 70 amps?
If it’s not NM cable then it might be OK. #6 THHN is good for 65 amps at 75° C. Next standard size OCPD is 70 amps.
What gauge wire do I need for 120 volts?
Household wiring for 120-V circuits is almost always 12- or 14-gauge copper wire, depending on the current load and length of the circuit. The diameter of the metal conductor in a 12-gauge copper wire is 0.0808 inches; of a 14-gauge wire is 0.0641 inches.

I’m putting a 70 amp sub panel in the gargare which has no service at all. Going to be running lights, garage opener and a few outlets. #3 copper will provide 70 amps at 240v with a 2.74% voltage drop or #1 aluminum at 2.83% drop at 200 feet. There is a mininum wire size which is required based on the circuit breaker rating.
Which is larger 120 volts or 240 volts?
Basic wire sizing guide for US 120 and 240 volts Added by: snoofer Useful info: # = American Wire Gauge (AWG), the lower the number the larger the wire guage. “Service cable” is large insulated stranded copper cable (usually refers to single #4 wire and up).
How big is a 10 AWG copper wire?
A sample of 120 volts, single phase, copper wire, 144 feet (one half of a 288 foot circuit) with 10 amps load on it yields a number 10 awg wire size. Our calculator yields results that are within code in most locations however we advise you to check your local electrical code.
