AWG # 6 copper
Yes, a #10 wire will carry 30 amps for 30 feet. If the load is rated as continuous then the wire will have to be derated to 80% capacity which will leave you with 24 workable amps. If the load demands currents higher that 24 amps then you will have to go to the next wire size up which is a #8 which is rated at 45 amps.
14
A # 14 copper conductor will be fine to carry 8 amps at 120 volts. This size conductor is rated at 15 amps.
10 guage
30 amps is how much a 10-2 wire will carry at 110 feet. 10 gauge wire is only good for thirty amps per the national electrical code. Using 80% of the breakers usage you will actually be getting only 24 amps.
Couple of things wrong here. 30 isn't a wire size. If you mean a wire that can carry 30 amps that would be # 10. Now it depends on how many # 10 wires you want to put into a conduit that governs the size of the conduit.
You will need a 40 amp breaker using AWG # 8 wire running it a distance of no more than 50 feet.
To answer this question a voltage must be given.
For a distance of 8 feet and a current of 52 amps, a 6-gauge copper wire would be suitable to safely carry the load while minimizing voltage drop. It's important to adhere to local electrical codes and standards when selecting and installing wiring for any electrical system.
To carry 20 amps over a distance of 100 feet, you typically need to use at least 10-gauge wire for copper or 8-gauge wire for aluminum. This accounts for voltage drop and ensures safe operation. Always consider local codes and regulations, and consult a professional electrician if unsure.
The distance that a 6 gauge wire can carry 50 amps depends on factors like voltage drop and wire insulation. In general, a 6 gauge wire can carry 50 amps for up to 60-70 feet without significant voltage drop. However, it is recommended to consult with a professional electrician for accurate calculations and safety considerations.
Wire is sized by the amperage that it is allowed to legally carry. To answer this question the amperage that you need at the garage must be stated.
