240 circuit with multiple receptacles?

[ManOnTheCouch]

Right now I have a 240 volt circuit coming off a 50 amp breaker to a NEMA 14-50 receptacle. I have my lift plugged into that outlet and hard wired to the lift via 10-3 SOOW cord.

I’d like to add an additional outlet near my lift to run my welder. I’ve done plenty of work with 120 lines, but not too much with 240.

Would it be a problem to hardwire my lift to the existing line via the box on the existing outlet, then add another outlet near the lift with the circuit continuing to the lift if not more than one appliance is ever used at the same time?

I understand it would potentially be a problem if I tried to use more than one thing my at a time, but if I limited it to one, would that be ok?

Thanks

Define "problem". Code says single outlet only on any line over 20A. Can it be done? Yes.

Interested. I was planning on doing this as well. Another member had said his electrician wired it for him

That doesn't mean it's legal. Remember, a lot of things are possible and they will work. It's the insurance and selling the property ramifications that should be considered. Don't always believe you will be around when the property sells. In that case it's things like this that throw wrenches into the works.

Welders work well on properly sized extension cords run from near the panel if running a new circuit is difficult. If you have limited room in the panel, swap in a quad or two.

The NEC doesn't address multiple outlets on circuits greater than 20A but International Residential Building Code does. It doesn't allow it. IRC E3702.5

This is the issue, and it does come up here regularly thank you for posting it.

There is 1 other issue. You used 10 which is good but wonder if there is a max breaker rating for the lift? It might be 30A

I have a welder on my lift wire. Its for a small 240 feeder and at 30A. The lift or welder does not use 4 wire but 3. A 6 space panel is cheap, a guy could feed it and have 120/240 and tailor the breaker for the equipment.
It would allow for local disconnect, could wire the hoist to the breaker, could install a proper welder outlet. The 14-50 is for ranges and motorhomes.

Thanks Zeke. I'll just run another conduit for the welder. Putting it on one side of my lift with a 15 or 20 foot cord will allow me to weld in a large area.

What welder is this? I don't weld from it and hoist at the same time and if it did worse is to trip the breaker but,,,, it wont happen. In my case the hoist and the welder can use the same breaker and I used a 10 wire anyway.
There wouldn't be a problem with yours either especially since there is likely a huge wire but many of the hoists do not have additional protection and rely on the breaker for short circuit. If it connects to smaller wires within the unit, smaller than 12 then it is likely sposed to be on a current limited circuit.

Thanks. Knew it wasn't allowed in one of the codes, forgot which one and listed incorrectly.

I will echo the just because you can, doesn mean you should. Also, getting all of those wires in a standard box would be tight (and I know NEC has box fill limits [emoji1] ).

Looks like I’ll put in an additional breaker and circuit. Was hoping to avoid it, but I’d rather do it right. Thanks for the good advice.
