Ground for 400 amp service
Ground size for 30, 40, and 50 amp breaker. Well, it is mandatory to take the gauge size based on the amp of the breaker. The ground size for the 30 amp breaker is 9 or 10 gauge. Also, for a 40 amp breaker the maximum ground size you will need is 7 or 8 gauge. Finally, for a maximum 50 amp breaker, the ground size can be 5 or 6 gauge.Let's start with some terminology to make this easier to understand, the conductor run to each grounding electrode is a grounding electrode conductor or GEC. GEC's are sized according to 250.66. A GEC to a ground rod electrode is not required to be larger than #6. The correct size for a GEC to a water pipe is typically a #4 copper or #2 ...
