NEMA 10-20 Receptacle Install
I am searching for a receptacle with the NEMA 10-20 configuration. I have found a limited number of them but they all stipulate non-grounding. The 2 hot lines have brass screws and the 3rd leg has a silver screw which tells me it needs to be wired to a neutral.
The plug that will eventually go into this clearly has the ground symbol on it. Would it be safe to use if I ran the 3rd leg to neutral as stated with the receptacle? If not, does anyone know of a manufacture that sells a receptacle that would mate correctly with the plug?

Moved to its own thread.
What is this for? What is the voltage and amps of what it is for? That plug would be for 120/240 20 amp no ground. That would be an unusual residential device. Sounds like it has the wrong plug on it.

That receptacle/plug would only be used for extremely rare old equipment, maybe some niche industry uses. The boiler almost certainly has the wrong plug on it.
The grounding 240V version would be NEMA 6-20 and the grounding 120/240V version would be NEMA 14-20. One of these is likely the correct one depending on whether the boiler uses only 240V or both 240V and 120V.
