Sue is dead on, on running extenstion cords that far. That is not only dangerous from heat in the cords but could hurt your system from voltage drop as she said. I tried running a cord 100 foot and it got pretty darn hot. Your cords would have to be VERY heavy duty. Heck you would have 150 bucks in cords if not more. smile PVC only costs a couple bucks per 10 foot. No brainer there what you should do. You can run the PVC and have no problems at all. Some fella's out here run PVC 8, 900 feet to run their air so 300 is not an issue.

The only difference between a rut and a Grave is the depth. So get up get out of that rut and get moving!! Time to work!!
