Oops, a three-phase meter with only two phases connected? Could that unbalanced load cause trouble too?
If that were the case, they wouldn't be using a single 3 phase meter for domestic use here. The first house I lived in, built in 1967, had a single 3 phase meter, so they've been around at least that long. Obviously in a residential situation the current draw on each phase is seldom going to be equal. Older houses here have a separate meter for each phase and the kw/h are merely added together for billing purposes.
