ground fault circuit interrupter (GFCI) plug trips....

There are two ways that receptacle can be wired. One is taking the hot (black) side from the GFI socket to the next and to the next etc. So they are all in common black--down the line from the GFI. Same for the white, or neutral, and green or ground.

Now if you took 3 triplex wires off one breaker. The first one to a GFI, and the next to a receptacle, without going thru the GFI, and the third the same, a separate set of wires from the breaker, then the second and third are not protected by the GFI.

In this case, the first are daisy chained, the second instance are not daisy chained, but both are in parallel.

Series is entirely different and normally not used in 110 AC or 12 DC in boats. It is more commonly used in speaker wiring--and there will be a difference in impedance in those in series and parallel.

In local Boy's instance, using a different breaker, from the common 110 volt bus, there will be no GFI protection on the microwave plug.

Bob, specifically I was curious about your setup where you said you daisy chained the other outlets to the gfci outlet. I guess that would mean all black wires to a common screw terminal, all whites to a comm terminal etc, kind of a star formation outward to the 2 other outlets.Am I on track?

Chucko, this is where it may gets confusing--and perhaps where the idea of "serial" came in. For the GFI to work down the line, there had to be a common connection with the GFI plug. That can be with one wire going to the next plug, and attaching another wire to the next, or it can be a set of triplex wire to each plug from the GFI plug--makes no difference--and since there are usually only two or three plugs in most C Dories, it can be done either way. However you don't want more than two ring terminals per screw--better only one. Each plug should have two screws on each side--the ground is where it can pile up--since there is usually only one ground screw on each receptacle.
