filter capacitors between all three wires (Hot, Neutral, and Ground) in the EMC line filters of
many computer and military electronic systems. At power-on and often while operating there
may be enough leakage current through the capacitors, between Hot and Ground especially, to
falsely trip the GFCI. Even for ungrounded two (2) wire devices, the power-on surge into
inductive or capacitive loads as presented by switching power supplies may falsely trip the
GFCI. This is more likely to happen with multiple devices plugged into the same GFCI
protected outlet especially if they are controlled by a common power switch.
Ground fault currents can properly result from deteriorating wiring; contact contamination due to
moisture, oil or dust; insulation breakdown; or other conditions which are indicators that repairs
need to be made.
We have verified the operation of the QuietPower 1800 for compatibility with the PAC-216/U
and VB-90 adapters for SINCGARS, the PAC-24V adapter for the Falcon series, the StarPower
solar power system, laptop and desktop computer systems (including monitors and laser
printers), cellular telephone rechargers, fluorescent lamps, and Uninterruptable Power Supplies
manufactured by APS. This system is also compatible with personal electronics (radios) and,
importantly, most coffee makers.
