Two GFCI Devices On A Single Line ?
Hello:
Moved into a 30 yr old house that has, apparently, one circuit going to an outside outlet having a GFCI circuit breaker in the main service panel. Being so old, I have doubts about how good the GFCI circuit breaker may be, but really don't want to play with the panel and replace the breaker. Any reason not to just add an additional individual GFCI outlet in place of the outside outlet there now (leaving the circuit breaker in the service panel alone) ? Guess I'm asking if there is any harm, or potential problems, in having two, possibly both being functional, GFCI devices on a single branch line ? Thanks, Bob |

What leads you to believe that the GFCI breaker is 30 years old? What leads you to believe that there is anything wrong with it? Any reason not to just add an additional individual GFCI outlet in place of the outside outlet there now (leaving the circuit breaker in the service panel alone) ? Waste of time and money. If you're concerned about the condition of the GFCI breaker, it's simple enough to test it to see if it works. Does it trip when you press the TEST button on the breaker? Does it trip when you press the button on a plug-in tester? If yes to both, leave it alone. Guess I'm asking if there is any harm, or potential problems, in having two, possibly both being functional, GFCI devices on a single branch line ? Obviously the potential for nuisance trips is at least doubled. And it will be more of a headache to reset two devices than one, if a fault trips both of them. -- Regards, Doug Miller (alphageek at milmac dot com) Nobody ever left footprints in the sands of time by sitting on his butt.

Just my opinion, but if it was me I'd put in a regular breaker and a GFCI
receptacle. That way if I was using the receptacle and it tripped, I would not have to travel to the panel to reset it. Yah Yah I know it shouldn't be tripping, but they do. I have a GFCI in the bathroom that trips 9 out of 10 times the hair dryer is plugged into it. Reset it and it's fine. Poop happens. "Robert11" wrote in message ...

As others posted, press the test button. It duplicates a
dangerous condition to humans; tests the GFCI. If the GFCI is OK, then it will trip. However newer GFCIs have an even better advantage. Should the GFCI fail, then the circuit cannot be restored until the GFCI is replaced. Like everything else electronic in the house, the GFCI can be damaged by external transients - ie lightning. Then when you needed the protection most, the GFCI would not be working. That is unless you periodically press the test button. In the meantime, new GFCIs now have a safety lockout feature. If the GFCI in the box trips, then the GFCI outside also must be reset - and in that order.
