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

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.

I just purchased a 4 position cam switch to be used to operate a 3-speed blower motor. The motor is a 10 amp motor and has 3 wires that are used to control speed. The cam switch was rated at 660V 20 amps but when I received it, I noticed that it has AC-15 operational current rating (Ie) of 4/5 amps. If I am reading the label correctly. the 4/5 amps is related to 440v/220V (Ue). Other ratings are AC-3: 5.5A, AC2: 7.5A and AC-4: 1.5A. My questions are 1) Is it safe to use this switch with the motor I have 2) what is the difference between the 20 amp Ith ratting and the Ie operational ratings?
