I have built a work shop in my back yard, I want to put a sub box in the shed.
The shed is 2 1/2 ft. from my main breaker box. I plan on putting a 100 amp
Breaker in the main box to feed the work shop sub box. The sub box will have
Separate c/b's for all the circuit's but no main breaker. My question is do I have to have a separate grounding rod for the sub box even though the grounding rod for the main box is just outside, or can I use the same rod as the main box? If I must use separate rod how far apart do they have to be?
