I am installation a 60 amp subpanel in a workshop in mine backyard and I will have 2 - 20 amp services with 4-5 outlets ~ above each and 1 - 15 amp company for lighting. The size from the main panel to the workshop is around 105 feet. I will certainly be making use of a twin pole 60 and GFI circuit breaker in the key panel to a 60 amp pull the end on outside of job-related shop then inside to the subpanel. What would certainly be a great size wire. I may run one saw at a time or a couple of saws.

6AWG copper wire would be the minimum because that a 60A subpanel but with a 105ft distance you have actually too lot voltage drop and also need come go as much as 4AWG copper to keep the voltage drop in ~ acceptable limits (usually 5%).

The National electric Code publication / post 110.14 (c)(1) identify temperature restrictions for circuits and feeders the 100 amp or less. If the circuit is 100 amp or less you have to size the conductors based on the 60-degree celsius obelisk unless the breaker and the devices terminations are rated for 75 or 90 degrees.

You need to use a #4 conductor to feed a 60 amp circuit.
