I have an unused electrical plug outlet that I want to tie into and run 110v to the barn. The plug outlet is 72 feet from the circuit breaker then from the plug outlet to the barn is another 70 feet or so. Is that too long a run or is it within specs?Thanks
Danny is right, if all your doing is putting up some lights you could use an extension cord if you wanted. The point here is low voltage will only mean your bulbs will be dim, however, some fluorescents may not light if the voltage is too low. If you are ever going to power a saw or any other tool from the barn, a 30 amp sub-panel would be ideal. Low voltage will damage electric motors.

If the unused electrical plug outlet is the only one on a specific breaker in the main panel then you probably could. One problem is - How many and the size of what you are going to plug into the two new outlets. The size of the cable is another problem. the further you run and the more things you have plugged in - the larger the cable. Another - To bury the cable you will need Special underground, (UF), rated cable. Buried cable needs to be larger then overhead cable due to lack of heat dissipation. Usually a buried 120V cable has to be a minimum of 30 deep and some require schedule 40 PVC conduit or pre-assembled cable inside special, black, coiled conduit. Another - the cable from the main panel - to the unused outlet - needs to be the same size as the new cable to out-buildings so . . . It would be better to run a specific cable from the main panel and not tie into the unused outlet. It can be done unless you are planning on running much more than a few lights or low wattage accessories?.
