I have a large induction motor that is rated for about 19 amps atand about 9. My 15 amp table saw motor also has a tendency to trip the breaker when it first starts, depending on what else is running on the same circuit. At volts also referred to as orthe amperage for a given device is halved. This means that you can safely run thinner gauge wire, which is cheaper. The increased amperage also helps an induction motor spin up faster.
Certain machines that require a lot of power, such as really big bandsaws and large welders, can only be run on This makes it handy to have available in any shop. Contrary to popular belief, switching from to does not increase the power available in a typical motor. Disclaimer: I am not an electrician.
Doing my own work is legal where I live, but it may be illegal where you live. This writeup is documenting what I did for entertainment purposes. It is not a course or instruction manual. You should consult a professional before doing ANY electric work on your house. There are a few items required to install a new outlet, all of which are readily available at the Home Depot or any similar store.
My outlet was going into my basement shop, which already had exposed conduit and outlet boxes screwed directly into cinderblock. In other words, it is not framed. I also had to get some conduit to run between the outlet box and the ceiling. This stuff is extremely cheap at any home store. You could also use the galvanized boxes and conduit, but plastic seems easier to work with and less likely to conduct.
Also required is a outlet and circuit breaker. These need to be sized for the required load. In my case, I knew my lo would be amps. There are multiple styles of outlet, but the linked R is a very common plug type for woodworking equipment. This is much more common with kitchen appliances than tools. Also be aware that different outlets are rated for different maximum power. Be sure to get one large enough. There are also multiple styles of circuit breaker, so I had to be sure to match the same type as what was already in the breaker box.
Details are outside the scope of this article. The last thing I needed was wire. This needs to be sized to the breaker and outlet as well. For 20 amps, 12 gauge wiring is appropriate. As I said, I chose 12 gauge to match my 20 amp circuit. Foryou have two hots and a ground. You can get wirewhich is a bit more expensive, but has two hots one black, one reda ground unsheathedand a neutral white.
You need for the aforementioned case where you have an appliance requiring both and volts. For tools, as I said, this generally does not apply. I chose to cheap out and get In my area, this is perfectly find and up to code as long as you mark the white wire with red. You can do this with liquid tape, red electrical tape, or my choice, red heat shrink. The point here is that an electrician will treat the white wire as neutral and therefore safe.
The first step in the process is to mount the outlet box to hold the outlet. Tapcon includes an appropriately-sized pilot hole drill bit with their larger screw packs. Once the pilot hole is drilled, the PVC box can be mounted using that one screw location. Lastly, all 4 screws can be put in. Red heatshrink applied to white wire to indicate it will be hot. The next step is to wire up an outlet into the box.
To start, I stripped the end of the wire I bought and added red heatshrink to the white wire to make it clear to the next guy that this is a hot, not a neutral. If you read the next step, I kind of wish I had waited to do this. The easiest approach is to cut the conduit to size. You can use a hacksawmiter sawor oscillating multitool else for this purpose. Pull the un-stripped wire through the cut down conduit, and then through the top of the box. Let the conduit dangle. Nowgo strip the wire, apply the red heat shrink, and curl the ends to attach to the box.
Trying to push the stripped wire through the conduit was pretty annoying. The important thing is that the unshielded ground attaches to the green screw, and the two hots attach to the other two. After that, I was able to pull the wiring back until only a few inches were left. I pulled it farther than pictured. At that point, I could simply push the outlet into the box and screw it down. Finally, How do you hook up a 220 outlet got the cover put on, completing the installation of the box. It should now be firmly mounted in place. Same procedure with Tapcons as the outlet box.
The next step was to secure the conduit to the wall. These attach in much the same way as the outlet box. I simply sunk them in with a couple of Tapcons.
At this point, the outlet box is done, and completely secured to the wall. I now just have to run the wire along the joists on the ceiling to the breaker panel. Drilling holes to go through the joists as needed. Since my basement shop is not framed up or finished, it was really easy to run the wiring. I simply followed what the original builders had done and used large staples to secure the wire along the joist.
To go through the joists towards the wall, I drilled a hole as pictured. Once I reached the far wall, I again followed the staple method to get to the breaker box. For a finished basement, this would have required a lot less stapling, but a lot more fishing of wire with fish rodsfish tapeor something similar.
To be honest, I hate doing that kind of job and would probably hire somebody. In fact, I did just that, adding this second outlet on the way to the breaker box. The basic procedure is the same, except that both outlets tie into the junction box at the top right. The electric code in most areas does not allow wire nut connections to sit out in the open, for obvious reasons. They must be in a junction box. I could get an oversized outlet box and jam extra connections into it.
Instead, I simply put in a second junction box. Wires from both outlets, as well as the breaker box, run to this junction box. They are all connected together with wire nuts and enclosed safely inside to avoid fire risk.How do you hook up a 220 outlet
