I just picked up a 1/3 hp motor and I need to put a cord on it. I'm not sure how to hook it up. There's a diagram, but I don't know how to read it. It needs to rotate clockwise. First, I need to know what gauge wire I need. I picked up a 14 gauge extension cord that I was planning to cut the female end off. Is 14 gauge the right size? Could I get by with 16 gauge, or should I use 12 gauge? I'd also like to put a switch on it. Home Depot didn't have anything with a switch in the cord, so I was thinking of using a power strip with a switch. I haven't cut the end off the extension cord yet. Will the wires be standard colors inside every extension cord?

The larger the wire the better your motor will work. 14g should be OK but 12g is better. Is this a used motor or a new motor?
I can't tell from the picture which post the blue wire is on.
For 115V CW rotation you need Post 1 - white wire post 2 - red wire post 3 - blue wire post 4 - black wire
L1 is the black wire from your cord (assuming your cord is black/white/ bare or green, if it is not you need to figure out which one is the line) L2 is the white wire from your cord The ground (bare or green wire from your cord) goes on the green screw.
Have fun with it...............Tony

sure is easier to connect in that tight spot if you put these on the extension cord wires and a deep socket nut driver(shallow in photo), be careful not to drop the nut down into the motor

Thanks Tony W, I just realized that I hadn't seen the L1 and L2 inside the motor. I just noticed the numbers, but missed the L. So I just attach the black wire from my cord to the L1 screw and the white wire to the L2 screw. I did know that the ground went to the green. James, I have a nut driver and I planned to buy the little wire ends. But I think I'll get this kind so I don't have to even use a nut driver. The motor was sold as used, and it might be used, but it looks brand new. I came in the original (opened) box with directions. I didn't find the instruction sheet very useful though. Here's a better picture of the motor:

Existing stake-ons are right-angle jobbers.
Got enough depth for straight ones?

You could always bend 'em over, if need be.

I think I have some right angle jobbers in the basement that will work.
James, I decided that I'd steal the 1/4 horse motor from my outdoor saw since I won't be using it for a few months. I took it off the saw and brought it downstairs and attempted to attach it. The holes were the right width, but I didn't notice that they had been enlarged to fit the saw. The base turned out to be too long to adjust the tension on the belt. I couldn't even get the belt on. So I went to eBay looking for a motor again. I found one that looked perfect for fifty buck plus fifteen for shipping. Then I noticed that it was listed as shipping from my own town. I sent a message and five minutes later the guy called me. I had his son in class last year. The next day I drove over to his house and saved the shipping cost. I couldn't believe that a random motor search turned one up ten minutes away.

what are the chances. probability off the chart. That is a fluke
motor connection diagrams written for electricians and geniuses, like ink is expensive.

To further confuse the issue, some manufacturers use CW as viewed from back and others as CW from shaft. It is a two wire switch to reverse if rotation is wrong. That is a good brand motor even if made in Mexico.

Yep, what John said. I discovered that after installing a heavy 1hp motor on the clubs 24 inch saw. Due to the inconvenient motor placement I had to remove it to get to the wires to get the direction right.
