Here are a couple of pictures of panels that are existing to the building, but the EC is using for temporary power. As an inspector, I would not permit this. During my inspection, I would tell them the correction had to be made IMMEDIATELY. I would give them a couple of hours, and I would come back to check this. It has been the normal routine in this area and now we are trying to stop this method. It is starting to occur.
What's the problem? This is temporary wiring for the convenience of the contractors. Who hasn't done something like this when it's needed? What matters is whether the final product meets code.
If you're going to complain that the temporary wiring isn't properly supported at the panel, then why stop there? Demand that the romex be nailed up and protected all the way back to the receptacles. What the heck, if it's commercial property, don't even let 'em use romex for temporary wiring at all -- demand MC or AC. Where do you draw the line?
The point is, I see nothing inherently unsafe about this practice. Anybody in the construction trades walking by these rats nests will give them wide berth.
The only problem I'd have is if the building is occupied and the area is accessible to tenants, in which case the panels should be closed up and the wires secured against accidental movement.
Now, how come phase C in the top picture is white, and if it's an existing panel, where's the conduit for the feeder???

John I hope you are kidding. The reason I posted these pictures is because the practice you see is pretty common, but is deplorable. It is not professional or safe in any manner, and does not comform to many code requirements. Your response is pretty typical for contractors who have not learned the proper way to install electrical installations, whether temporary or permanent.
BTW: This work gets red tagged every time, and is considered hazardous, so I also make sure that it is corrected IMMEDIATELY.
A question to add to this post. These installations are in dwellings. The installer leaves at night to go home. The homeowner has no lights, as during the day one of the circuits has been tripped during the construction. Would anyone feel comfortable with having the homeowner trying to reset one of these circuit breakers?
