Took yesterday off to run a new main electrical feed into my garage, that part went well. Discovered after when I went to hook everything up that the wiring in the walls was far more terrifying than I anticipated, so started rewiring all of that. Was hoping to weld my floor pan in today but have 2 more circuits to wire first. At least my garage won't burn down from bad wiring now.
I figure I should say what terrifying is, the whole garage being run off of a 20 amp circut that also happened to run a couple rooms in the front of my house. It was run off of a single piece of 10/2 romex direct buried under the concrete slab of my breezeway. This ran to a 40 amp fuse box with a knife switch in it and out to all of the outlets and lights in the garage. All of this I already knew... Upon looking at it further, the outlets were all fed with 14 gauge with one of them run off of a piece of extension cord buried in the wall. The lights are run with 12/2 MC cable with no ground, which I fixed as well as I could and left. All of the outlet wiring was disconnected and capped in the boxes with the outlets removed. It has all been verified as dead as well.
So far I've added a 100 amp breaker to my main disconnect panel, run 2 guage 4 conductor wire out to a new 12 position main lug panel, which contains two circuts for outlets, one for lights, one for a welder, and one that runs my air compressor. All the new wire is 12/2 (except welder) and all of the horizontal runs are along the ceiling to prevent grinding/ welding debris from sitting on it and melting holes. The whole garage is insulated with blown in insulation so its all surface mounted because that's a can of worms I didnt feel like opening.
