GCM technology allows the plug
or connector to look upstream, or
toward the panel. As seen in (Fig.A),
a break in ground continuity or re-
versed polarity from the receptacle
back to the panel will be indicated
by a Red LED on the plug body im-
mediately upon insertion.
Conversely, the Green LED is illumi-
nated in (Fig.B) because the prob-
lem lies downstream of the GCM
plug, in the cord itself. Therefore,
the plug sees no problem.
This setup, using both a GCM plug
and connector, will also be very
helpful in troubleshooting. A green
light on the plug and a red light on
the connector tells you that your
problem exists within the cordset.
However, red lights on both ends in-
dicate a definite problem behind the
wall, as well as a potential problem
with the cordset.
