white, black, red wires/GFI receptacle
white carries unused power back. Black n Red carry power in (to power your crap) But be careful ( if black wire is attached to a breaker at the electrical panel that is labeled an even number and the Red is attached to an odd number (hard to notice stamped numbering on cover beside breakers) Odd to odd OK Odd to even Not ok = 240 boom! So if Black X and red Y then proceed with: black to Line holes on gfi (crap hooked up to Load) Red wire dont hook up, twist together to pass to next location. Next location hook red to LINE on gfi and dont connect black. just don't land black and red on same location, red gfi = microwave black gfi = fridge red gfi = blender black gfi = coffee maker White wire should go directly to each gfi without detour. don't use white from load or line off gfi but twist a bunch so 1 white hits black gfi 1 one white hits red gfi 2, back gfi 2, red gfi 2 ....etc.
regular non-gfi rules
you can share the white wire coming from any receptacle with the same color as long as the same colored wire and it's brother white wire are hooked up to a known even or odd label (stamped next to breakers) odd to even cross 120+120=240 even to even 120+120=0 since its the same Phase (odds are phase 1 separated from power on phase 2 evens) odds are all virtually the same 120 evens are virtually common with each other at 120. red and black make 240, red and red make 120 did i miss anything?
