Question:
Good Morning,
When a electrical service is being upgraded with new equipment. Question is do the circuit breakers for all existing circuits have to be changed to AFCI type? What code would support that they do not need too. But only new circuits.
Thank you.

Answer:
Hello Randy,
Thanks for the question. Check the exception to 210.12(D). For a service upgrade, this exception may be applied if the conditions in the exception are met. It is also important to verify this with the local authority having jurisdiction, which may have amendments or additional rules that modify this exception. Hope this is useful.
