Question:
Hello CQD,
If you replace a Type SE cable from the meter base to the electrical panel, do you have to upgrade grounding system to an existing electrical service?

A
Answer:
Hello Jose, and thanks for the question. The NEC is typically not retroactive. However, on a replacement project like that mentioned in the questions, an inspection and utility service clearance is often required, which would necessitate an inspection or at least a verification that a grounding electrode system in compliance with 250.50 was still in place for the service.
