Daisy Chained GFCI Protection

Where did this myth come from? :slaphead:

I'm pretty sure it was a guy named Eddie.

Not quite the same thing as claiming daisy chained GFCI's won't play well together......

It's not a 'claim'. Back in the early days, daisy-chained GFCI's didn't play well together.

.....I do think six foot from the sink should have been left as the rule all along, and the more recent dishwasher GFCI requirement was just about criminal as to why it is required.

There's a lot of stupid rules in the NEC now. They're really dumbing it down for the maintenance guy at the factory and the handy-hack. My favorite is now requiring the white to be reidentified as ungrounded when used in switch loops.

I was not aware they once didn't play well together. What was the difference from those to today's units that makes that particular difference? I know quality units today will tolerate inductive kick back better then the older ones. But the basic concept of only tripping when current flows outside a designated path is fairly unchanged.

I agree reidentifying white is nothing more then dumbing it down for the untrained, and it still don't work for some of them.
