Thanks Doug

I have a timer like the one in link that I use on the pump for the pond pump that works great for that type of job.

I have been playing with a device for a long time, (for the comp.) the one I have come with will pull a 50amp. beaker in a box that the power cord plugs iinto for the comp.,it runs off a clock IC with a 12volt DC relay that runs a auto. door lock/trunk device that will pull or push the breaker off and on but it's so dam big, but it needs to be because of the 50amp. pull of the comp. I just need to find a electrical engineer to get all the parts into a standard outlet box for a 50amp.service... 12 volt 15amp. power supply,breaker,outlet,12 volt relay,IC clock,etc. lot's of luck

Bob,

You could use a water heater timer ($20), or some other heavy duty timer, so that your compressor won't start up at night. I can't think of a 'cheap' way of putting a 15 minute run time on your compressor, a good 20 amp TDOE relay can be $60 plus.

The switch I listed below has a bunch of trips, you could set it so it could only run every other 15 minutes during the normal day.......

(I just kill the 2 20 amp breakers in my shop when I leave)
