Figure 250-160 is illustrating section 250.118(5) (Flexible Metal Conduit) and says:
"A bonding conductor is required when a circuit protection device exceeds 20A, or the fault current path of the conduit exceeds 6 ft"
However, in the actual NEC, 250.118(5) does not contain the word "or".
This illustration in the Grounding vs Bonding book indicates that FMC may be used as a EGC regardless of it's length as long as the OCPD is not over 20A.
Is the book in error? Is my interpretation of this section in error?
Thanks in advance. :-?
