Hi I am testing an older VGA projector. At my friends 10 year old house the projector tripped the GFI receptacle. At my 30 year old house the projector did not trip the GFI I have. Assuming the receptacles are the original to each house, is his receptacle faulty or did later model GFI’s have different trip specs? His GFI’s power other devices ok. Thanks for replying
If the device in your house is 30 years old I would guess that the 30 year old device is the problem.
Imbalance of current, not current loading trip gfi’s
Thanks for the quick response. I was looking at a Code Revision pdf of GFI from the 1970’s to now. I could not find if the newer one’s are more sensitive than older one’s. So it’s the imbalance of the wires that trips it, that’s good to know. Thanks again.
