I have an inexpensive Qualtek computer input line filter that is rated 
250 VAC at 3 amps.According to the schematic on the side, the third wire 
is grounded to the chassis on both sides of the filter.  Would such an 
arrangement make for better filtering by solving the pin 1 problem, for 
the device using it?
