Since the thread was closed on the other forum, I'd like to post the following observations.
Don't confuse empirical data with anecdotal data. Unless you're taking measurements in a recognized scientific manner, any observations in the field about GFI's & refridgerators is strictlyt anecdotal.
GFI receptacles amaze me to no end. I'm currently on a job that is served by one GFI receptacle (it actually works & has been tested). On most days, there is approximately 1500 to 2000 feet of cord plugged into it with no trouble. I don't have enough fingers & toes to count the 3 way splitters.
However, if there is the least little bit of fog in the morning,out comes the WD-40, becuse the GFI keeps tripping.
