Circuit breaker blanks

That is why you drill an insulated drain hole in the bottom of the enclosure.
In some cases the existing hole for the GEC will do the job. (Since the amps are trying to get to "ground".)

That's my point if you're comparing metal to plastic. I have no problem with using plastic blanks but find the wording of that section to be somewhat fuzzy and open to interpretation.

Wouldn't the meaning of sustantially be a lesser value of equivalent? Metal & plastic in the case of a breaker blank are not equivalent but as a comparasion to value of protection within the context of its use as a breaker blank there is a substantially similar protection provided ---- tomato - tomaatto

Wouldn't the meaning of substantially [equivalent] be a lesser value of equivalent?

Yes, in this case...

...but not substantially.
