2 Post Lift Wiring - DIY w/ Limit and Shut Off Switches

Here is how I wired my Atlas Pro-9D clear-floor 9000lb automotive 2-post lift. This lift uses a limit/interrupt switch on the top cross bar to prevent a vehicle from going too high. I also added a safety shutoff switch - this is recommended by Altas, and also required by code in some areas. I used a Leviton 2-pole 30amp/240v switch in a Leviton enclosure. The electrical sub panel in my pole barn is a Square D QO 100 amp panel, and I used a 30 amp double pole breaker. The wire is 10-2 nm-b romex.

    White wire connected to a breaker should be taped red or blacked since its not a neutral, other than that everthing looks great, I like how you did the exposed portion in flex steel conduit and secured it to the hoist.

    Great walk through! Like the cutoff switch with the lock-out-tag-out groove, can't wait to see more
  • Very clean install! I do like the motor starter switch. I'll be honest, I installed my disconnect box and clips to the lift with good ol' fashioned #8 self tappers. They worked a treat, the columns are thick but soft.

    Sweet setup, I'm installing a 4-post lift at my house and this was very helpful in helping me decide how to wire the power unit. I'll be posting at least 3 videos about my install too, Thanks for posting.

    Nice clean work! Im wiring a 220v lift today that is very similar. Nice explanation on the cut off switch wiring. Going to implement that into what i am doing!

    Good job I'm about to install two of them this week and appreciate your video

    Thanks, I ordered the switch and enclosure like yours. I was just going to put a single pole cut off but this is so clean and I like the hole I can put a hitch pin clip into. I won't need to lock it.
  • thx for the video....i just had a the Atlas 9KOH installed...should have done it myself....anyways, I used your idea to add a switch. I mounted mine directly to the column and I used a 20amp switch and used 12 gauge stranded wire to a 20amp/220volt breaker.

    Great video! Surely helped a lot of people including me. Thanks.
  • @schuck9326
    Thanks excellent video and professional detail. Really enjoy your videos without all the music, jokes and unimportant nonsense others include. thanks again!!

    I have the same Atlas lift and the cheap contacts inside the contactor intermittently welded shut! This kept the motor & lift running until it hit the upper bar limit switch. You mentioned that you installed the emergency shutoff in case the up button sticks, well it’s not just the button that could stick and in my case it was the cheap contacts in the white relay contactor. The contacts melted together.

    Best video on YouTube about this! Thanks bud
  • did the switch need to be double pole to run both hots through it? my diagram that came with my lift only shows using one of the hots to go through the limit switch and also inline with the manual shut off switch same wire. i am about to do a rough wire up to run the pump and bleed the cylinders. still looking for a manual cutoff switch to use.
  • Trying to put in a new button switch for the up and down of the lift and having problems getting the incoming power white and black wires to the line side of the pump and the normally open and common side of the button how do you wire the new button in is what I’m asking?
  • My switch broke in the on position. Lucky for me when I put my lift in outside I only had one permanent 220 source (my well) so I just added an outlet with a cut off switch to my well and when I want to use the lift I plug it in so when the switch on the lift locked into the on position I just unplugged it. No it’s not technically to any code but when used only one appliance is used but works for me at my home where no one cares but me. I’m just glad I had the option to turn it off. It’s an old lift so no fancy interrupter switch. One day I’ll change it… Been saying that for 10 yrs….
