The size of the bond conductor didn't hit my radar but now that I look at it, I'm going to challenge your rejection of my work based on ground conductor size.

Maybe #14 loomex was a bad example because 10-814(1) says the bond doesn't need to be larger than the largest ungrounded conductor. (That actually makes sense)

Appendix B 10-814(1) says "In any case, the bonding conductor incorporated into a cable assembly is deemed to be of adequate size for the purposes of this rule." So, I'm not changing out my 12 loomex, either.

In the American version of the CEC (2012) #14, 90C is good for 25 amps, so it can be tied onto a 70 amp circuit subject to the distance limitation.

Are you using Table 16? According to that table, a 14 bond is too small for 14 loomex at 25 amps.

I don't see how this can create inspection chaos. Just pretend there are no rules and you'll be pretty close.
