240v Welder, Air compressor, GFCI?
In a detached garage, do the receptacles for a 240v plug-in welder and a 240v plug-in air compressor need to be GFCI protected, like the other general purpose receptacles?
Do they make 240v GFCI outlet receptacles? If not, would those receptacles need
to be protected by GFCI breakers?
If the compressor was hard wired, would it need GFCI protection?
Thanky!

there are very few stuff that required 240 volt GFCI useally found in pressure washer but not too wide spread due the motor starting surge and current pulseation can wreack hovac with gfci devices.
but the best bet is check with the manufacter to see the spec if they requred or not.
i work on alot of air commpressor and it is very rare for 240v and higher commpressor requried GFCI due the starting surge and load cycling but it might change in future i really can't say it will must have it but some area might requried but most area it will be ok. { check with your local inspector for local code issue there }
Merci , Marc
