[AMRadio] FW: 220 vac line

Mon Jul 25 11:33:13 EDT 2011

Ground is not used as the fault mechanism in a GFCI.  GFCI's are looking at 
a current differential between 4 mA and 6mA between line and neutral 
conductors only.  A GFCI, when correctly installed and working, will perform 
it's job with only a two-wire line cord that uses only line and neutral, and 
no ground conductor.

Paul, W9AC
