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.
AWG 10.
AWG # 14 is the smallest wire you can install in a home and it can only be used in living areas. It will carry 15 amps.
At the service entrance you will need AWG 1/0 gauge.
6 AWG.
10 amps
AWG # 6 copper
AWG 10.
AWG # 14 is the smallest wire you can install in a home and it can only be used in living areas. It will carry 15 amps.
A 12 AWG wire is typically rated for 20 amps in standard household wiring. At 240 volts, this wire can safely carry up to 20 amps of current.
Yes the ampacity of #12 is 20 amps whereas the ampacity of #14 is 15 amps, so you are well within the range using #12 wire.
At the service entrance you will need AWG 1/0 gauge.
14 AWG of 105 degree Celsius copper wire is rated for twenty-five 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.
6 AWG.
Service wire required is AWG # 3/0 copper.
30 Amps
A#18 copper conductor with an insulation factor of 90 degrees C is rated at 6 amps.
