Well, I managed to get out to the breaker box to do this today, but discovered that it won’t be possible until I get some help from the power company (the city).
The problem is that, although I can get into the breaker box in order to recover when circuit trips, etc, the compartment where I’d need to get to in order to access the mains is locked. 
So, I called and left a msg and will hopefully be able to get back to this in the next day or so…
