For practical intents and purposes, no.
With sophisticated equipment, I'm sure one could measure a slight increase after a while with a load on it, however, it would not be a problem.
I'm not recalling anything which prohibits sloppy work like that, other than ones own pride in their work (which, obviously, was non-existent there).
That is, other than the vague:
- NEC
- - 110.12 Mechanical Execution of Work.
