Pierre: No, I wasn't kidding. I simply contend that the degree of care required for such temporary arrangements depends on the circumstances, including duration of the work, accessibility to non-qualified persons, and occupancy during construction. What if the panel is in a locked room, to which only qualified personnel have access? Would you still object?
These are probably not so guarded, and so I'll grant you that the missing covers are probably a real violation, as Reno pointed out. But if the temporary receptacles are integral GFCI types, then there might not even be any other violations here.
In your hypothetical case of an occupied dwelling, I think I made it clear that a much higher degree of support and physical protection is required.
Your response is pretty typical for contractors who have not learned the proper way to install electrical installations, whether temporary or permanent.
Golly, that's a little harsh. Didn't I just say that how important it is that the final product meets code? You have no idea how many hours I've spent making my own installations "over-the-top" neat and workmanlike. Even the temporary ones.
