Garage Heater using a Nemo 16-50 Receptacle.

***Note that thread title should be 6-50 not 16-50 but I am unable to edit the title***

I'm looking to use a basic plug in heater for my single bay detached garage for this winter for the odd day I plan on working on my car in the garage. Previous home owner installed a Nemo 6-50 receptacle for use with a welder, but I'm having a hard time tracking down a plug in heater that comes with a male 6-50 plug.

Alternatively, I already have a old used heater handed down to me that LOOKS like its a 6-50 plug, but the prongs are just a bit too wide apart to fit a 6-50 receptacle.

That being said, I'm also having a hard time finding a plug adapter that will allow me to use the old heater so I looked into new heaters, but nothing I've found comes with a 6-50 plug.

Any suggestions?

I have one of these that I picked up a few years ago for $75 on clearance: Your friend has shared a link to a Home Depot product they think you would be interested in seeing:

CadetThe Hot One 4000-Watt 240-Volt Electric Garage Portable Heater
https://www.homedepot.com/p/Cadet-T...tric-Garage-Portable-Heater-RCP402S/100351722

It came with a 6-20P plug and the cord was just a bit too short for where I planned to mount it so I bought some 8-3 SOOW wire and a 6-50P and swapped the cord out so I could plug it into the welder receptacle like you are asking.

Double check the Nema 16-50 markings. 16 indicates a 480 volt, 3 phase, 3 pole, 4 wire configuration. If you have a 16-50 recept in your home it is the wrong part.

It may actually be a 6-50 designation.

Then the next q's are:
What is the Nema configuration on the heater plug?
What is the heater nameplate information?
What cb and wire size feed the recept in the garage?

Pics of each will help.

You are correct, its a 6-50...I just mistyped here. Going to update the thread title and info here right now.

Will upload pics of the heater plug and outlet right now too.

Here is an image of the plug from the heater. Its old, and doesn't have any "nemo" stamping or code numbering.

Which is connected to this style of heater - taken from internet because I dont have a photo of the actual heater.

And here is the 6-50 receptacle installed in my garage.

Your plug does not look like a 6-50. Look at the blade sizes, they are both the same where the receptacle uses one smaller than the other.

Thats a weird plug, it does not conform to NEMA standards, I cant find anything about it.

Assuming that's a 220v heater... Cut the plug off, Wire in a Nema 6-50 plug. make sure ground is on the round pin and the other two wires can be on either blade.

As long as the circuit breaker and wiring to the socket is correct for the load from the heater you should have no problems. I have seen a 6-50 plug (a 50amp rated plug) wired to a 30amp breaker, do not upsize the breaker unless the wiring can handle it. almost never is the wiring larger then it needs to be for the breaker since it's expensive.

The plug you hold up might be a 5-50P, which is 120vac, 50a!

Need the the heater nameplate info to go any further.

How you taken voltage readings at the recept?
