Stealing 110v power source from lift 220v power supply

[JasonF]

I did some searching but I get a pretty good mix of whether what I want to do is doable.
When I built my barn I planned ahead for a two post lift install and put a junction box on the ceiling with 10/3 wire ran to it. I've now installed the lift and I'm really regretting not running a second wire for an outlet mounted next to my cut off switch as the ceiling is scissor trussed and has since been finished with insulation, steel and has no access.
Can I use one of the 220 legs for a 20amp duplex outlet with the following scenario?
I ended up only needing a 20amp breaker for the lift so that is what I have to the ceiling even though the wire is rated for 30amps. The lift then uses the red/black and ground and the neutral is not needed for the 220v lift motor. So now I still have the neutral unused and available at the ceiling which would then be used with one of the hots for the duplex. The outlet would be used to charge rechargeable stick lights and maybe a shop vac but it's highly unlikely that anything of any real amp draw should be running at the same time a vehicle is being lifted.
My plan would be to run a second 12/2 wire to the junction box at the ceiling, then steal one hot, use the unused neutral and share the ground? Thoughts?
Photo sort of showing my set-up, outlet would go in the gang box with by cut off switch.

Yes you can do what you are asking as long as the breaker is not increased above 20A.

I have a receptacle mounted on the ceiling by the lift for a retractable shop light. It's wired exactly that way.

 

[JasonF]

Yep, no plan to run higher than a 20amp breaker. A lift I had looked at before settling on this one needed a 25amp breaker which was the reason for the heavier gauge wire.
Cool, thanks fellas.

Also the 120V outlet needs to be gfci.

To add to this question:
Can you add 2 duplex gfci outlets, one from each leg (mwbc?) & share the neutral since the handles are tied together at the breaker?

Multiwire Branch Circuits NEC 210.4 | JADE Learning

A common application of multiwire branch circuits as described in section 210.4 is for a 120/240-volt, single-phase system where three wires do the work of four, the two ungrounded conductors sharing a single neutral.In a 20 amp multiwire branch circuit if the two ungrounded conductors each...

I THINK the use and load would need to be considered. 210.23A2 - The total rating of utilization equipment fastened in place, other than luminaires, shall not exceed 50 percent of the branch-circuit ampere rating where lighting units, cord-and-plug-connected utilization equipment not fastened in place, or both, are also supplied.

Thanks, but I already understood the concept of a mwbc (probably from this fourm) but I was mostly wondering if this was a practical use for one, & if the 220 breaker satisfied the handle tie requirement.

As others have said, if the handles are tied at the breaker and the breaker is kept at 20A, you can land the neutral in your panel and add a service receptacle at the lift between the neutral and one of the phases as long as the load of what you plan on plugging in combined with the load of the lift do not exceed the 20A rating of the circuit protection.

You can also do this on larger amperage / higher voltage equipment by using a 2500VA transformer go from the equipment voltage to 125V and then install a din rail circuit breaker between the transformer and the service receptacle.

Because they are service receptacles and installed in a garage environment, the receptacles are required to be GFCI protected circuits.

Just my two cents!

Just pull a neutral down the same conduit and change out the switch cover for one for a switch and outlet.

All receptacles are required to have GFCI protection, & if on the 2020 NEC, 240V also.

Definitely not code, but something I've seen done before. A sub panel mounted on the lift, with a 2 pole breaker for the lift, and a breaker or two for a receptacle (or two).

How do you figure that's not code allowable?

Mostly around the working space clearance.

I'm on the process of running a split phase 120/240v circuit to a recep for a 2hp bandsaw motor. Originally I thought it was exempt from GFCI requirement but now I'm not sure. I see someone mentioned it on the 2020 NEC. Is that the first NEC that requires it? I'm looking to see what NEC version our area is using. I just looked at dual pole 20amp GFCI breakers and yikes, they are not cheap.

I believe in alot of cases that would be a non-issue. In my case there is plenty of standing space to place a small panel on one of the lift columns.
