Help a brain dead fellow out. I will be installing some electronic devises at a correctional facility. These devises are mounted on poles around the outside of the facility ( 4 poles ). Each devise must have a dedicated 120v circuit and has a load of 4 amps. Here is the problem. By the voltage drop calculations 2 of those circuits ( 460ft, 560ft ) must be # 6 THHN and the other 2 ( 1640 ft, 1740ft )must be #3 THHN due to the distance from a UPS panel inside of the prison to the devises. I think I can land the #6 on a SP 30 but unsure of the #3. Only other option is to put a short pig tail on the wire and land on 20 amp SP breaker.
