NFPA 20 versus NEC

[hhsting]

Size of BKR #1 is not relevant to 250.122(D)(2).

You know motor HP, figure the maximum permitted dual-element fuse for that HP, and size the EGC per that fuse size.

David luchini what if their is another breaker upstream of fire pump ATS controller per 695.4(B)(2)(a)(2) then how should you size the EGC?
