Hardwire a plug in shop heater?

[toddt429]

I have a shop heater that has a plug. It's a 240v 4000 watt heater. Any issues with hard-wiring it? I don't have an outlet in stock here. It's going to be fairly temporary. I feel like it shouldn't be unsafe to do so. Just want some opinions if I could please. Thanks.

Realistically depends on what the manufacturer calls out. Is there a reason you can't just buy a receptacle online?

I think by hardwiring it you are calling it a permanent installation, cabtyre is usually not permitted for permanent installation , and probably the heater isn't rated for it either.

can you/ will it work? yes
should you? probably not .

Wouldn't bother me in my own shop one little bit.

My heaviest shop branch circuits are 30A, so I won't hesitate to use a 4-5kW heater on a welding circuit, taking advantage of the common 6-50p plug. Or a similar approach with the dryer receptacle and cord whip salvaged off a dead appliance.

I could get a receptacle, I was just hoping to hook it up today.

I'd be fine with it in my shop too, but I'd want some form of strain relief for the cord. If really temporary, a NM clamp would do it

I'm sorry, I wasn't clear on that. I wasn't planning on just cutting the plug off. I was going to run 10 wire from panel to heater.

I wasn't going to use the original cord. I would run it from pannel to heater and did plan on strain relief at the heater.

Code-wise, you'd need a disconnect of some sort unless the panel is in sight and the breaker is capable of being locked in the off position.

A cord-and-plug satisfies this requirement, so does an actual disconnect switch.
