New member to the forum. I recently moved out of my parents house and purchased a 1940's house on a 1/2 acre lot. The house has a single car attached garage and a double car deattached garage. Woodworking has been a interest of mine for years. During high school I lived in the wood shop and I remember building lots of things with my father while growing up. I already had a small collection of my own tools that I used when living at my parents house so when I bought this house I knew right away I needed my own wood shop. When I bought this house the previos owner was in the process of finishing the single car attached garage. When I looked at the house he had wiring in the garage for lights and plugs but nothing was finished. The garage was fully insulated. Just needed vapor barrier and wall covering. I assumed I would just continue from where he left off and turn this area into a small wood shop for myself. After looking at the previos owners work more closely though I realized he had 12/2 wire ran from the main panel into a sub panel in the attached garage. The black and white wire of the 12/2 wire were both attached to their own 20A breaker and he was using the bare ground wire as the neutral! There was no ground at all in the shop. After seeing that and knowing 12 gauge wire wasnt going to cut it for the power I wanted I gutted everything he had done and ran 8/3 tied to a 40A breaker from the main to a brand new square d sub panel in the shop. He also had seven pot lights installed in the shop. I removed those and installed three 8' T8 lights. I am now in the process of trying to plan my plugs around the shop. I originally was going to wire all my 110V plugs with 12 gauge and have all 20A plugs. But I have tons of 14/2 wire that I pulled out from the shop and would like to use it since I have it. So I am fighting with the idea of doing all 20A plugs or 15A plugs with a few 20A plugs. Right now the only tool I have that requires 20A is my Ridgid table saw. I do plan on adding a dust collector when funds permit and realize that will most likely need a 20A circuit also. I have drawn up a rough idea of how I was going to wire my plugs and would like some advice and input from you guys who have shops already and know what works and what doesnt. Thanks alot.
Edit- In the picture I planned on spacing outlets approx every 4' around the shop. The majority of my plugs would be 15A seperated onto two circuits. I was going to have four 20A plugs separated over two circuits. I have no need for 220V and am not sure if I ever will.
