So he was curious and asked why. I told him the wire is wrong, the
breaker is wrong, and what about connectors and staples. The breaker
was the only one they had that would fit a Cutler-Hammer panel. Told
him that you can't mix brands, that you need a Cutler-Hammer breaker.
Well, that part is wrong. He can mix brands just fine, as long as the
breaker will mount in the box. No requirement for a CH breaker, depending
on the box he's using.

Actually, there *is* such a requirement. Even though a Cutler-Hammer breaker
will fit, and function, perfectly in a Siemens box, for example, it's still a
Code violation to use it -- because the CH breaker wasn't tested in, and
therefore isn't listed for use in, a Siemens box, and it's a Code violation to
use any electrical device for a purpose for which it's not listed.

But, that doesn't mean the breaker the customer had wasn't a
replacement-brand breaker manufactured for the purpose by another
manufacturer.

Many of the original CH breakers are now obsolete and only third-party,
NOS, remanufactured or other replacements are available.

Upshot is, insufficient evidence to say unequivocally the selected
breaker wasn't ok for the panel; overly restrictive to say that only a
CH-manufactured breaker can go in a CH panel. It has to be made as a
replacement and listed as a replacement for the panel, true, but it
doesn't have to be manufactured only by CH.
