Looks good! You should try it with your heaviest vehicle @ 20 amp and check the draw with clamp meter. From the people who own that lift, I have heard that they don't have any issues. One person I know uses a high magnetic breaker, the rest don't.
PS: Are you going to put a bigger leveling piece under the rear left post?
I'll be checking that once I have a heavier vehicle available.
I used a couple scrap pieces of 3/4 plywood to shim up the columns to get them more level. I have a fair bit of slope front to back in the garage. Side to side is perfectly level. I will be cutting a few pieces of 2x10 bigger than the baseplates which should be the right thickness to make it perfectly level. Might need additional small shims under them to make the columns plumb. I will need to buy or build longer ramps since that will impact the approach angle. Too many low cars.

I don't have your lift but my Triumph C7000 has the same electrical requirements. I installed the 10 ga wire, 30 amp 110 breaker, 20 amp plug because they don't make a 30 amp in standard plug format. Routinely lift 4000 lbs with 0 issues. Been working fine for 2 years. I really struggled with the wire coming from the pump to the plug as it can't be more than 12 ga but it works. I've read others statements it's the initial startup that can spike to 30 amps. Never investigated on my own as the lift works perfectly.
I wouldn't hesitate to do it again.

Mount a disconnect on it ,instead of a cord.

I'm glad this works for you but it just seems wrong. You have a 20-amp plug on a 30-amp breaker, that's gotta be against code, and even more so isn't providing you with the proper circuit protection.
I really think that this was a mistake in the instructions. There are thousands of these lifts, basically identical, that are working - and have been working - just fine with a 120V/20amp circuit. This 30 amp requirement doesn't make sense.

20 amp high-magnetic breaker has never tripped my Atlas Pro 9000 with over 6000 lbs on it

Not sure what you mean by standard plug format. But these will carry 30A and meet code on a 120V circuit.

He's referring to a 5-15R, because the lift comes with a 5-15P on the cordNot sure what you mean by standard plug format. But these will carry 30A and meet code on a 120V circuit.

I considered that, but he said 20A and a 5-15R is 15A. A 15R or 20R on a 30A breaker is a fail.

Hi all, I read all the posts above but still not sure. I just bought a used Atlas 9000 2 post lift, it is currently wired for 220 on a 2 pull 30 amp breaker. I don't have 220 in my garage, and was wondering if I could run it on a 120 outlet. I am just going to be using it occasionally for oil changes etc. Three questions: !) will 120 run the hydraulic motor at all. 2) If so will it keep tripping a breaker. 3) Do I have to do anything special to convert or just use the white wire as as the neutral.

- Probably better to start your own thread
- Going to need to post a pic of the motor/ wiring diagram
- If you can convert it the wire(s) need to be moved somewhere, likely at the motor
in addition to above post, you need to tell us what amperage your 120 volt outlet is as well.

No way to answer that without a pic of the motor nameplate.
What is the rating of the breaker that feeds the garage?
Regardless, if the motor is 240v only, your options are, run a new feeder to the garage or use a 120v to 240v transformer. However, if the 120v feeder to your garage is power limited you may have issues with nuisance trips of the feeding breaker
And i agree with above
Start a new thread instead of hi-jacking this one

Thanks for all the responses and help!!!
I got some more information about the Atlas 9000 Motor and attached some pictures.
Motor = 2hp
factory wired at 230VAC.
60HZ,
15-18AMP,
208-230 Volt,
See pictures
The wiring to my garage is the Ameron Green Box ran to a 20amp breaker then 250ft of buried 10-2 wire brought into the barn. From there I have several outlets ran off of the 10-2 feed with 12-2 and 14-2 wiring.
Not a very good setup, I am considering rerunning a larger wire and putting a breaker box into the garage. I assume that I could put a much larger breaker than 20amp on the temp pole. At this time though I am wanting to run the lift off one of outlets or straight to the 10-2 wiring.

if you dont have 240v available in the garage how did you wire the lift to a 240v 30a circuit? where did you put the 30a DP breaker if you dont have a breaker box in your garage per your reply below?
1. no you cant run it on 120v. the motor is 208-230v only
2. the breaker is tripping because you are running a 240v motor on 120v. that just isnt gonna work.
3. this motor cannot be converted to 120v operation. you need to run a new feeder.
oh boy this is a huge mess
no you cant use a much larger breaker. you have #14 NM which should be on a 15a breaker. not to mention 250' of #10 with a motor load is gonna have massive voltage drop on startup. another reason for tripping breakers
honestly this is way over your head. get an electrician to set this up properly for you before you burn the house down.

He's buying the lift... It isn't hooked up to 120v and tripping a breaker.
@blakeb1969 you need to run a new electrical service to make this work.
I'd start your own thread with specifics and we can help advise
x3
Otherwise the responses are going to be a confusing mix match bas d in the 2 situations from separate people.

huh? he literally said he bought it wired it to a double pole 30a breaker and showed pics of it installed. also stated its tripping breakers.
agreed on starting a new thread

Reread it. The previous owner has it on a 30a 240v and he's asking if it will trip the breaker on 120v in his shop. He didn't say he's trying to run it on 120

he didnt say anything about previous owner and he specifically said "will it keep tripping a breaker." which leads one to believe that it is tripping the breaker right now...
I got a warning the other day for a very similar situation where an ancient thread got bumped and I was trying to figure out what another user was talking about. Perfect reason why the new user should start his own thread...
@wyliesdiesels what post are you looking at? See number 51

It sure does change when the "If so" is removed.
I'm sure my English teacher could explain the phraseology. Something about the sequential dependency of the 3 clauses.
Bottom line is ain't no way that 240V motor gonna run onna buck twenty volts. Boy would she be pissed.

im looking at 51. he said "2) If so will it keep tripping a breaker."
this implies that it has been tripping a breaker
he made no mention of any previous owner whatsoever either
wyliesdiesels

the incorrect word he used was "keep"
if he had just said 'if so, will it trip the breaker', it would have had an entirely different implication and context.

@wyliesdiesels fair enough.
I guess @mike93lx and I both took this to be the used lift was wired from the previous owner for 220
Certainly a lot to be desired with how this is phrased if we're being pedantic. Wth is a 2 pull breaker?

2 pole. he misspelled it
I know.
Back to the question, I don't see anyway to wire this for 120v, do you?
Assuming not, then the questions about breaker tripping are moot, he cannot run a 240v motor in his 120v shop.*
*Barring options that we shouldn't discuss here to keep it uncluttered

Sorry for all the confusion, I am starting new thread. https://www.garagejournal.com/forum/threads/powering-a-car-lift-with-a-generator.542563/

I never once had the thought that he had ran it and was tripping the breaker. I guess that's one of the idiosyncrasies of the english language , stuff can be interpreted different ways
