I'm sure this has been asked before but I've been searching the forums and maybe I'm just not looking in the right place. I've never had to wire a motor before and I will absolutely consult my buddy who is an electrician
before going "hot" but I'd like to see if anyone on here knows what I need to pick up before starting.
My motor is a Marathon electric 1hp tefc farm duty 1725 single phase motor
I know I'm going to want to upgrade eventually, but for now this is what I have.

I'm assuming I can pick up a toggle switch from HD or Grainger, but as there are so many available I don't know what to get.
My motor came with a pigtail and I'm going to initially use it on 110 with step pulleys going to a kmg grinder.
The wiring diagram I have is as follows:


Low volt P1 to Line 1

Blue and T1 to Insulate

Red, P2, and orange to insulate

Black, white, and yellow to line 2

I've wired radios and electronics before, but putting a switch in is new to me and any advice would be appreciated.
Thanks
 
We can't see the photos


We need to see all the info on the data plate on the motor

You will have to use photobucket or something like that before you post them here.


I like to switch both sides in case neutral and hot are reversed somewhere


Get a double pole, single throw switch rated for more than 1 HP
1.5 or 2 hp Gardner Bender toggle switches should be available from home depot

put Line 1 and line 2 to those switch contacts, power from the wall to the other side of the switch


I bet that motor uses more than 12 amps, so use 12 gauge wire and plug it into a 20 amp outlet and circuit.

Thanks for your help,
Above are the links to the plate. Hopefully they work, if not, I'll have to get a photobucket like you suggested.
 
Well Home Depot had the exact toggle switch you
recommended. The employee working in the aisle said I didn't need a Rubber boot or any type of enclosure
to install it so I'll give it a try in a little while.
Once again thanks very much for your help!
 
Ok, I finally had time to wire this thing up with the switch. My buddy said the double pole switch isn't needed for low volt but when I go to a high volt I will use it.
I haven't turned it on yet, just wanted to get it looked at before I go hot!
I put it in a blog because it's easier to see what I did.

The double pole switch was recommended so neutral can be switched as well in case you unkowingly have a wiring fault. I would also recommend a better strain relief than the one in your pictures. It doesn't look like it would keep the cord safe from pulling out in the event of a snag. I use the arlington brand connectors from Menards.
 
The switch was confusing to me because I couldn't
Find any info on wiring it to a motor. How would I wire the neutral? The same way I did the power wire?
Would I cut a section of the neutral away from the power cord so the neutral from the power cord is going into
the switch and the cutoff section is wired to the other side of the switch then connected to black, white, and yellow from
the motor?
Is this just an extra safety measure?
Thank you

Yes that it
 
Thank you guys very much! The motor is up and running with no problems. All I need now is a grinder! I contacted Rob from Beaumont metal works and hope to purchase a kmg from him within the next couple of weeks because this hand filing is taking a REALLY long time.
I really appreciate all the input.
