Two electronic energy meters are connected to seperate
phase wires, but connected to a looped neutral. Are these
going to function correctly?

Answer Posted / guru
No, when using the electronic energy meters the neutral
should be seperately connected and not a looping.
For example if any fault currents occur in any one of the
phase both the energy will be recorded.
Secondly and main point is electronic energy meters work on
the principle of taking the higher current reading ( Either
it may be in phase or neutral) so if 02 neutrals connected
in loop the sum of the neutral current on both the circuits
will be recorded and the energy value will not be right one.
