One of the benefits of modular construction is that the electrical circuits are wired and inspected on the factory floor, so once their installed it's easy to get the real electrical service up and running. Many projects don't even need temporary electrical service, and we're fortunate to have generous neighbors who let us borrow a circuit's worth.
Not so easy in Newton, however...
The modules are wired, the panel installed and half-wired, and grounded to two 8-foot copper rods driven under the basement. But the electrical inspector says we can't get service until the water line is in. Since we can't dig for the water line until April 15, we're going to have to keep running on temporary power.
National Electrical Code says service must be grounded through two electrodes, just like we did. The water line, if present, may substitute for one of the electrodes but you still need two.
Massachusetts Code is slightly different, says that if a water line is present you must ground the electrical service through it.
Newton interpretation is that if a water line will be present you must ground the electrical service through it. No water, no electricity.
Kind of pointless and irritating, but not really a big deal. We are going to run into bigger problems in the utility reconnection, though: the water, gas, and sewer fiefdoms all have their own issues and inertias.
