Outdoor Shed Wiring

I'm helping my neighbor wire his outdoor shed with lighting, A/C, & outlets. (120 Volts only)

We're installing a circuit breaker panel (without a main breaker) in the shed and are powering it from the main breaker panel in the house. We are installing a double 70A breaker to serve as a main in the shed and will install a breaker in the house.

We purchased direct burial cables (2-#2 AWG aluminum & 1-#4 AWG aluminum), but I'm not sure how to connect the cables. I'm assuming the two larger cables are the hot & neutral, but how do I connect the 2 terminals on my main breaker in the shed? How do I connect them to the double breaker in the house?

Ok,,, If you use 6 spaces or less you do not need a main in the shed. Use the 70 in the house. Get another piece of no.2 equel to the ones you have and mark if with white tape on both ends. Use that as neutral wire from panel to panel and use the 2 others to feed from the breaker to the main lugs in the second panel. Then use the no.4 from the equipment ground or the neutral bar in the main panel to the equipment ground bar (seperate from the neutral) in the second panel. Then pound ground rod outside and run a ground wire,, min no.8 I believe to the equip ground bar. Do not use the bond screw in panel 2 to bond the neutral to the box. There are several posts in previous pages about wiring sheds with drawings. Here is the address of the site by Goodrich. http://www.homewiringandmore.com/hom...detgarage.html
