Question:
Good Morning,
Our inspection group really values the thoughtful responses you provide. Section 110.24 requires the available fault current be field marked on the service equipment. Where would I find the value of available fault current to meet this requirement?
Thanks in advance for your response.

Answer:
Hello Paula and thank you for the question. The serving utility company typically provides or publishes this information. See Informational Note No. 2 following Section110.24(A) in the 2020 NEC.
