I got a letter from Eastwood telling me to shut off their scroll compressor whenever it's not being used since there is a risk of fire if a line blows and/or it otherwise runs too long. Apparently, that happened to someone with this compressor, with bad results, prompting Eastwood to send an orange warning sticker (because orange warning stickers fix everything).

So...I'm looking for a good way to turn the compressor off and on from inside the garage. The circuit breaker is too far away, and running wires through the wall for a switch looks like a nightmare (but maybe). Any electrical types here know of a plug n play 240v relay with remote control? The compressor specs say it takes a 20 amp 240v (and is running single phase). Any ideas?

I have that type of remote setup for my dust collector. Here's the product: https://www.clearvuecyclones.com/produc ... th-remote/

Pretty sure there's nothing in about that's specific to the dust collection application - it just powers a 5 HP 240V motor...

I've seen a number of them for dust collectors. Why would dust collectors need remotes more than other stuff? That is the first one I've seem good to 30 amps, so just might work. Do I understand correctly that you have to plug it into a normal 120v outlet to work, separate from the 240v it is switching?

Yes, they need 120V to power the part of the unit that receives the remote signal. The 240V is simply for switched relay. It might be possible, in theory, to use 1 leg of the 240, stepped down. But the heavy draw on starting the 240V motor probably would have adverse effects on a parasitic 120 use...

Big dust collectors are usually located in a far corner of a woodshop (or even in a separate room, like mine). While having a hard switch somewhere near the center of the shop would be OK, since equipment is usually scattered all over the shop, a remote makes sense.

Should add - I have a hard switch on my air compressor. Turn it on in the morning, turn it off when I head out in the evening. But it regulates itself, doesn't run continuously.

Dust collector, OTOH, doesn't need to run all the time. Only when the machines are in use. So I'm turning it on and off a dozen (or more) times a day.

That's what I plan to do also. With a switch on the wall in the garage, it will just be much easier to turn off for the night. Currently, I have to go out behind the garage and climb over pool equipment, floaties, and innertubes to get to the switch...
