Franklin Dysthe
A
Answer:
Hey Franklin thanks for your question. The grounding electrode conductor for services must be connected as described in 250.24(A). The connection to a metal underground water pipe electrode can be made within the first 5 feet of where the pipe enters the building as stated in 250.68(C)(1). The NEC now requires all of the grounding electrodes described in 250.52(A)(1) through (A)(7) that are present to be bonded together and be used as the grounding electrode system as stated in 250.50.
