Welcome to the big show! Do you have any electrical experience so that you can do the work yourself? If so, it would not be very expensive to install a sub panel in the garage and run a few lines. Without experience I would suggest calling in an electrician. As to what to have installed, think hard before having a single line put in, see what the difference in cost would be.

I think you’ve already answered this:

Either, A) you’re comfortable around electricity. If this is the case, you can install a subpanel yourself. It’s just like installing a new branch circuit, just with a different device at the end and bigger wire.

Or, B) You’re not comfortable around electricity. Have an electrician do the work. Have him/her run the subpanel. Wire and a panel aren’t expensive. Labor is more expensive.

I don’t understand why everyone is terrified of wires. Electrical work is a discipline based on a set of rules, that are very explicitly spelled out in the NEC book.

I vote DIY sub-panel. If you can install a 20 A plug, you should be able to install a sub-panel. As always, work must be done to code. Whether there is some other reason it MUST be done by an electrician is between you and your local authorities.

It isn’t rocket science. There are plenty of how-tos on the internet. Not much more to it than picking the correct wire and breaker sizes and being sure to separate the neutral and ground connection in the sub-panel.

And no reason the sub even has to be permanent. Meaning, you can do it in a way that you can easily remove it when you go to sell. Of course, if you pull a permit and do it up pretty it should help resale value (or at least won’t hurt it).

All you need is 4 wires from the main panel (two 240 V wires, neutral and ground). Of course a breaker in the main, then to the sub panel. Bring conduit out from that. Your choice as to how many circuits and how much conduit to run around the garage. But it’s quick and not that expensive.

In a lot of ways, adding a sub panel is not much more complicated than wiring a wall plug. There are a few details, but again plenty of detailed info on the web.

Two years is still quite a bit of shop time. I would install the sub panel, just to not have any hassle or worries when doing woodworking.

Just to be clear, I am comfortable around electric but we are talking 100’ from the panel and inspections.

I was going to forego the inspection on the one 20 amp plug ran to the garage, because, really, who is even going to know. However, with a sub-panel I will have to get an inspection, our city is easy going so getting the inspection on the sub-panel is not too bad, but I am not sure it is worth the extra cost and effort.

Not sure where your panel is located now but if feasible I’d just run a 20amp for your dust collector and deal with it for a short time.

A sub panel can be installed, and when the time comes, removed. My neighbor had one we put in for 18 months and worked with all manner of equipment with no issues. When they showed the house he hid the sub panel with a box frame and when sold just removed it. Even passed a so called house inspection with no notice of it.

One more option is, install a 20 amp outlet near the box, then run a do-it-yourself extension cord.

I buy one hundred foot rolls of twelve gauge power cord. I prefer the three hundred volt because the insulation isn’t as thick as the six hundred volt, so it’s easier to install plugs and outlets. This allows me to replace defective cords and make extension cords for various uses.

On the matter of plugs and outlets, buy decent ones.

One advantage to this route is, you can take a good quality cord with you.

Have your say...
