I want to install a 100 amp sub panel in a shed located approx. 100' from the main house panel. The shed is a wood work shop where I will be using a variety of power tools from radial arm saw to table top saw. Is the 100 amp panel sufficient? What size wire should I use, I was told 6/3G. I will be using PVC conduit. I was told to connect the sub panel to a 50Amp breaker in the main panel. Is that sufficient or should I with a 60 amp breaker?
