Electrical Guru's needed..

Summer is here and it is frkn hot! I have 4 horses that like to stand in the barn. I put up 4 box fans that run 24x7 (horses appear to love the wind to keep the flys off), today I decided to try to wire a motion sensor so the fans wouldn't run when the horses weren't in the barn. It worked but not like I had wanted. I used a motion sensor that is used on flood lights.. apparently it can't pump out the amps that the fans need for them to run efficiently. The whole setup worked fine except the output.

So I now I was thinking I could keep using the motion sensor but wire it into a relay instead? But I'm not sure what type of relay to get (for AC Voltage) or where to get it from.

Suggestions!?

Grainger most likely will have the relay you need.

The problem is finding a relay big enough for the amps.

Figure out how many amps your fans pull. (should be on the boxes or a label on the fan motor, add all those up. That is your full load amps on the fans. now figure out what your total number is 80% of, this number is how many amps you need your relay to handle.

ex. 27 amp fan x 4 fans = 108 amps
108 amps is 80% 0f 135 amps
so you would purchase a relay for 135 amps

You add the 80% for start up fluctuation, in case your wondering!
