Hey PEP-folks,
At last, I again have room for my shop tablesaw. Alas, the shop didn't have 220V run to it. So, I am documenting the outlet installation task here, and will separately document the wire pulling BB.
Short summary: Tablesaw and blower are each rated 2hp, 12A, for a running-together current of 24A. This is 80% of a 30A circuit, so that's the breaker size I selected. The wire size appropriate to this circuit is 10AWG. The tools are both older, and are 3-wire 220V (L1, L2, GND), however, I chose to run 4 wires in case I ever want to swap things out for a newer 4-wire 220V layout (L1, L2, Neutral, GND). As the former owner did not choose to separately derive a ground for this building, it's a moot point anyway without adding ground rods and reviewing the connection to main panel (they probably pulled out L1/L2/GND), but adding wires to a run is a pain, so I laid in 4 conductors. The conductors chosen are solar-panel wire, rated for exposed outdoor use.
A further goal of this project was to not spend money and use up old inventory that I still have in my electrical totes. Thus, I think it looks kinda like garbage, compared to a project where a client is paying to have things look nice. The upshot, however, is that I did indeed spend zero new dollars to make this happen. Moreover, the only particularly ugly bit is the box extension, because the box was a bit crowded; this would go to a galvanized steel square box. I ganged it on the aluminum box that I had. And then put a plastic in-use cover on it, because it's in the shop, and is a dusty environment.
However, the saw and dust collector are happy now, and I have been able to do better joinery (I like tongue-and-grooves with a dado blade). It's been about 5 years since I've had this saw set up, and I am happy to have it back in business.
This short video demonstrates that yes, both tools start and run satisfactorily on the circuit.
Happy Homesteading!
