Minimizing GFCI vampire / phantom load loss and heat? Which model is most efficient?
Woah! There’s hot spots on my walls on the thermal cameras. It’s clear that each GFCI outlet is using power 24/7.
Can anyone provide a pointer to detailed measurements of GFCI (or AFCI) models and their standby, parasitic or “vampire” power draw? I see numbers all over the map from .1 Watt to 7 Watts.
The big vendors do not specify standby power consumption, and I have not yet found any EnergyStar or certification guidance. AFCI’s are of course controversial for a number of reasons: add to the list the standby power.
Any check your kitchens: a lot of them have redundant GFCI’s (only one is required, the rest benefit from the downstream protection if wired correctly).
