NOTE: The VerifEye
®
meter uses the NEUTRAL terminal as a voltage reference. For
systems without a neutral conductor, it is recommended to connect a ground wire
to this terminal. If the neutral terminal is left open, L-L measurements are accurate,
but L-N measurements may not be symmetric. If a ground wire is connected to the
NEUTRAL terminal, <2 mA ows into the ground wire.
