220 compressor light?

[PT Doc]

I use a 12 hour dial timer. I Installed it into the mag starter box (by drilling a 3/8 hole) and wired it in line with the pressure switch. When I go into the shop I turn the knob to the amount of time I think I will be working (say 3 hours) and forget about it. No need to "worry" about turning it off.

Any links to product?

Intermatic sells spring wound timers, there are other brands out there too.

I used this one Its rated for something like 15a 120v and 1 hp at 240v but its only controlling the coil portion, which is basically nothing

I drilled a hole in the mag starter box, (there was a lot of extra room in mine) and rigged it up inside, I basically took the wire that goes to the switch in the upper left, cut it in the middle and put this on both sides of the dial timer.

fatkid: This whole thread is about people who want to have their air compressor on and available whenever they are in their shops. They don't want to risk a fire or other damage if an air line happened to burst while they are out of the shop - causing the compressor to run non stop for hours on end. That's why they want a reminder to turn off the compressor when they leave for the night.

yes i understand that, but most of these people have high quality industrial units with 100% duty cycles to begin with. so if it did run for a few hours it really wouldn't hurt anything.

i guess i just thought the minimal risk was worth it to always have full PSI ready and waiting.

I don't understand your aversion to technology in this instance when I'm sure you have plenty of things that rely on it. Does your air compressor derive its energy from a steam engine that you fire with coal every day?

Wire up two 120V bulbs in series. Now you have a 240V bulb. Wire this in parallel with the feed to the compressor. If you're concerned about protection sizing and all that, wire the bulb holders with 6 gauge.

Wiring those lamps to a 30 A & larger circuit is not allowed.

I am not against tech but Norcal proves it out here,,, not allowed to wire these lights to larger circuits.
Many and most of these home brew ideas for this are not tested or listed or even designed by someone that isn't aware this light isn't legal,, this is my point. Its not that the fundamental idea is bad but that it doesn't solve many problems and introduces new ones that may even be hidden.
