I need to put together an extension cord to power my Foundry with 240 volt. This will be off our dryer outlet, going out to the garage for now, but I'll eventually have a brew kitchen in the laundry room when I'm able to remodel it. HVB gave me a GFCI unit to place in-line.
I guess the best way to do this is buy a dryer extension cord (the receptacle is the old three prong style) and splice the GFCI unit in in the middle? I was going to use heat shrink connectors for the splice.
This is the best deal I could find for the length I need (15-20 feet, at least). I guess demand is up due to people buying these to charge their EVs. Still seems expensive.
Any other ideas?
