If you dont have the ground bus grounded anywhere it should not trip because of a parallel path. Try plugging the extension cord in a non gfci outlet and place a gfci in or near the moved house and see if it trips. Roly Roly is pretty smart so I figured I'd try to estimate the capacitance of the 150' cable by guessing gauge and using some online calculators. I got an approximate value of around .002uf or thereabouts. Then I got to wonder what kind of sensitivity GFCI protectors feature and did some googling and came upon this: Quote:https://safeelectricity.org/ground-fault-circuit-interrupters-gfcis/ So I think Roly is onto something here (note the parts I set in italicized bold). |
