The new shop is coming along nicely and now I'm starting to rough in the wiring and I have a question.
Has anybody ever put 2 - 220v outlets on the same circuit? My table saw and Joiner sit next to each other. The table saw runs on 220. The joiner originally ran on 110, but in my old shop I had a concrete floor and was too much trouble to run a new 110 line and I didn't want cords running across the floor, so I converted it to 220 and just plugged and unplugged each one as needed. That turned out to be a pain. So I thought about putting a second 220 outlet in so I could leave the joiner plugged in. So I was wondering if I could just tap off the circuit for the table saw. The circuit is 20amp and even though it could handle both tools at the same time, I don't see myself running them at the same time, and I really don't want to take up breaker space for another 220v circuit. I only have 20 spots as it is. I've checked with a couple of residential electricians, and they say it's possible electrically to do, but they have never had a reason to. We've looked through the code and it doesn't really address it. It does address certain appliances/functions need to be on a dedicated breaker, but not if you can put two outlets on a 220 breaker.
So this boils down to four options
1. Keep things as they are and plug and unplug
2. Run 2 - 220v circuits, 1 for each tool
3. Convert the Joiner back to 110 and run a 110 outlet for it. (I am planning on 2 - 110 retractable cord reels from the ceiling, one near the table saw area to power the lunch box planer that sits on the out feed table and one near the workbench, and could possibly use it for the joiner, but still would need to unplug it when not in use.)
4. run a second outlet off the table saw circuit.
