Heater/lift wiring

[Cody27]

I currently have a 7500 watt heater in my garage. I wired it with 8/3 nmd90 on a 40amp breaker in my main 200amp panel in the house about 12 feet away.

I just installed a tmg tpl45 10k 2 post lift that requires a 30amp circuit. In this coming spring I will be doing a large garage addition, and during that time I will be adding a 100amp sub panel inside the garage.

My question is, can I wire a receptacle on the 8/3 and put a plug end on the heater and the lift and plug in whichever I am using at the time? The lift won't be used much, so I would unplug the heater and plug in the lift, use it then plug the heater back in.

Can I plug the lift into a recepticle on a 40amp breaker or do I need to run a new 10/3 30amp circuit? Otherwise downgrade to a 30amp breaker but I could only do that when the heater is no longer needed. Trying to avoid running a new line if possible. Thanks!

30 amp@ 240 v for a lift?

Lift manual states 25A cb or fuses....probably just for startup inrush.

Since the lift motor will only be operated while under supervision, I think your plan with a receptacle is fine.
It would be a 50a recept as there are no 40s.

Also makes provision for a future welder.

NEC would have you size the breaker to a maximum of what the manufacturer calls out for the lift and putting a cord on the heater if not called out (which I doubt) is also not code compliant.

Realistically? I'm sure people would be fine using a quality 3 HP NEMA 6-50/14-50 rated industrial receptacle and corresponding quality plugs with a 40A breaker.

The NMD90 means the OP is in the great white north.

OP, please add a location in your profile.

I'd do a 6-50 for this as well

Wait? There is a place connecting the continental United States & Alaska?!?

Good point.

Haha yes sorry I am in Ontario, Canada. You don't require a permit or inspection to do any electrical on our side of the meter (if youre not hiring a licensed contractor) which is kind of scary but at the same time convenient at times.

The lift does have it's own limit switch aswell. My main concern was whether or not I would be fine to plug it into a 40 amp circuit. I guess I could just add a disconnect switch inline on the lift post aswell.. code doesn't really matter as I dont require a permit or inspection here but would still be ideal to be compliant. This will all be removed when I do the shop addition and add the 100amp sub panel anyways.

You’re supposed to get permits and Inspections for electrical work in Ontario.

You should have a disconnect on the lift incase you have to kill power to it.
