I'm competent with GFCI and electircal wiring but I have a question
about this situation. All wiring is copper with ground.
I have one hot cable coming into a receptacle and two cables leaving
which each lead to a different electical outlet. Usually things are
wired in series instead of this situation I have. My plan was to
replace the regular outlet in this receptacle with a GFCI and just
attach both of the outgoing lines to the LOAD terminal of the GFCI.
However the instructions with the GFCI say "Do NOT install the GFCI
receptacle in an electrical box containing more than four wires (not
including the grouding wires)." Why do they say not to install a
GFCI if you have three cables in a receptacle? Is it just incase the
user cannot figure out which one is hot Hot or is there another
reason? Parallel wiring isn't common but i always assumed it was
just to avoid confusion as to where circuits are coming/going.
Any thoughts appreciated.
