Lift motor wiring

[kcautorepair]

Hey everyone, first post here. I'm in the process of installing a gilbarco/manitowoc gff-70 lift. I'm stumped with the wiring. From my understanding, the plug is a 110v plug, but the motor is a 220v. Anyone know what I need to do to get this wired up? I'm going to be running a dedicated circuit for the lift, I just don't want to buy the wrong wire. Attached are pictures of the plug that is already on the lift, and the info plate off the motor.

It's 240v, but just has the wrong plug. The plug needs to be a 6-20, not a 5-20. 20A circuit is fine using #12 wire.

Notice the non-molded plug on the lift. I'm assuming it is used and previous owner used whatever he had in the shop to install or repair it.

20 amp 2 pole breaker in the panel, #12 wire (2, any color except gray, white or green plus the ground, green only), a 20 amp 250 volt outlet and a new 20 amp 250 volt plug to replace the existing one.

If you're using a cable of some sort and it has black, white and green, you can use the white as a hot (one side of the breaker) but it must be identified as a hot. Red tape will do, coloring it with a sharpie works too.

wrong plug. pizza pete used whatever he had.... just swap it with a 6-20p and install a 6-20r with #12 and 20a breaker and you should be good to go

The issue besides the voltage rating on the 5-20 being 125v, the motor HP rating is only 1 HP.

To clarify, the plug on the lift was there when I purchased the lift. I want to make sure everything is correct before I attempt to plug it in. I wasn't aware that you could run a 220 v motor on 110v power. I have a 220 outlet not far from where the lift is that I can use for the lift, I just don't know 220v circuitry.

You cant.

The motor would need to be dual voltage rated, 115v/230v. Or, in your motors case, triple voltage rated (115v, 208-230v).

The original owner had to have it wired as 240v. They just used the wrong outlet and plug and wired as 240v. The neutral of the 5-20 was used as a hot. 240v is two hots whereas 120v is one hot and one neutral so the 5-20 can actually be wired as 240v.
