Re: First post - recently joined - GFCI without a ground wire
said by iLearn:Most probably that GFCI tripps because of too much capacitance (to ground) on the convoluted wiring. Separate circuits for each bathroom should fix that ... until you install bathroom heaters.
I just noticed that my GFCI outlet in the bathroom upstairs tripped. That circuit feeds the 2nd bathroom and the powder room as well.
