Hello. This is a very interesting and educational forum. I’ve enjoyed visiting, but I came across it by searching while looking for information.
I do some woodworking in our attached garage. The power comes from one 15 amp circuit. My dear bought me a new table saw that draws too much power when it first powers on, dimming the lights almost to the point of blowing the fuse. I haven't used it yet as a result.
The table saw is currently wired for 120V but can be wired for 240V, and we have a 30 amp 240 volt circuit for a range that is unused. The house was built in 1967 and has 100 amp service running through a Square D 125 amp rated fuse panel. The wire currently running to the range outlet is 8 gauge copper. The area of the garage I would be interested in running power to is 30 feet from the range outlet, and about 55 feet from the fuse panel.
My neighbor is an electrician, and said I could either:
Re-route the 240V line to the garage, and wire the saw for 240V, or
Use the 240V to feed two separate 20 amp gangboxes, using one hot for each box and the white as the neutral. (I'm assuming this is what he meant.)
What I was wondering is, could I use the 30A 240V to feed a small subpanel in the garage with one 20 and one 15 amp or two 20 amp circuits? I would never be using more than one tool at one time. That's ingrained in me by the limitations I'm already under by the single 15 AMP circuit, but it would be good to have extra outlets on that side of the garage on a separate circuit. The only outlets currently in the garage are 15 feet from where I work.
I pondered his second suggestion, but it didn't sound particularly safe to me. It's not that I believe he would suggest something unsafe, but he doesn't and hasn't done residential work in over 15 years and I would appreciate a second opinion before I go calling anyone.
I would truly appreciate any input. I'd like to go just go ahead and upgrade the fuse box to a breaker panel and just add another circuit, but that's not in our budget at this time.
Thank you in advance, and from what I've read around here, be careful today or tomorrow! (Not that any of you need to be told.)
