From an inspectors perspective, I call the utility and have the building disconnected. The general Contractor comes into the office and raves about having no power. I usually offer him the phone number to the WCB (like OSHA) and suggest he gets the temporary service he just removed returned. I have never had to do this twice with the same contractor. The electrical contractor often gets a $100 dollar ticket too. It is the ticket I hate to write since the electrical contractor is not usually the guy who created the hazard. The tile guy or whomever gets a ticket and loses the cheater cord too. If a Workers Compensation Inspector comes on site and sees something like this will write a $5000 tickets for first offences.
