GFCI in quadplex - protection down the line?

I'm installing some GFCIs and it is my understanding that if you start with a GFCI the recs 'downstream' get protection too. Yes?

So, I have power from the source coming to a quadplex rec and feeding from there to the 'left side' quadplex and 'right side' quadplex. I currently have grounds, neutrals and hots pigtailed and connected to both duplex recs. If I put a GFCI duplex into the first quadplex will it protect down the line?

Does it matter how I wire it in?

Is this one of the forest for the trees things I get obsessed about every now and then? Probably, I guess.


If I could only remember to THINK about what I was doing before I did it.

If you want receptacles downstream to be GFCI protected, you must wire as follows:

Power source to LINE terminals
Downstream receptacles to LOAD terminals.
Be sure to wire black to "Hot", brass colored screws, white "Neutral" to silver colored screws.
Also be sure that you wire the ground to the green screw of all receptacles.

Only the GFCI receptacle and everything properly wired to the LOAD terminals of the GFCI will be protected. Any other receptacles wired to the LINE terminals, or to the same circuit that feeds the LINE terminals of the GFCI will NOT be protected.
