I replaced an outlet today at a commercial site. Now I admit I don't know
anything about commercial electrical, but around here grounds are required
to be crimped residentially; wirenutting isn't allowed.

I was surprised to see the ground was wirenutted. I assume that if
crimping is required for residential, it would also be required for
commercial.

Is that likely to be a valid assumption or not?

You must be in a place that doesn't follow the NEC, therefore you need to
follow whatever rules that place uses
