A wiring diagram is a simplified conventional pictorial representation of an electrical circuit. It shows the components of the circuit as simplified shapes, and the power and signal connections between the devices.
10 3 Wire Amp Rating. Next to the implied question is 10 wire sufficient to carry 30 amps 75 feet. It doesn t seem right that this has a 60 amp breaker but i m not familiar with 220 v lines. For worst case calculation purposes we will assume 30 amps at 240 volts.

Next to the implied question is 10 wire sufficient to carry 30 amps 75 feet. 10 3 should be good for 25 amp or a little better depending on use of wire. There are 2 unused 20 amp 110 v circuits in the garage. For example 3 0 awg copper has an ampacity of 200 amps at 75 while 3 0 awg aluminum has an ampacity of 155 amps at 75.
You must use the correct size wire for the current load requirement of the circuit to prevent the wire from overheating.
Insulated wire types like thhn thwn 2 xhhw 2 and use 2 rhh rhw 2 have an insulation temperature rating of 90 and any temperature correction factors or ampacity adjustment factors can be applied to the insulation temperature rating. Electric cable sizes and amp ratings for the uk electrical resistance and cable rating tables. Voltage should not make any difference on the current carrying capacity ampacity of the wire. So kverrett to start with the maximum ampacity and overcurrent protection of 10 3 romex is 30 amps. The number and type of electrical devices connected to a circuit determine the ampacity requirement of the conductor.
10 3 Wire Amp Rating. 1 current ratings for up to 1000 v pvc insulated single and multicore wiring cables ambient temperature up to 30 o c values for resistance are based on electrical resistivity for copper 1 724 x 10 8 ω m 0 0174 μω m and electrical resistivity for aluminum 2 65 x 10 8 ω m 0 0265 μω m. 10 3 should be good for 25 amp or a little better depending on use of wire.
