While on the subject of house wiring and kWh meters, my former residence
had 2 legs of a 208 3-phase system for wiring (I verified w/ scope). I
just realized that my kWh meter probably UNDER-read my actual energy
consumption because for a line-to-neutral resistive load, the current
and voltage peaks are 30 degrees out-of-phase with eachother. For 
line-to-line resistive loads, the voltage and current are in-phase, thus
it would read correctly. Anyone concur ?
