split-neutral circuit and 2-pole breaker
|

| What I am referring to as a split-neutral circuit is what would
otherwise be a shared neutral circuit. But instead of one neutral
wire, there are two. The circuit feeds a box of 2 receptacles for
4 120 volt outlets. One neutral is paired with one hot wire, and
the other neutral is paired with the other hot wire. Thus if there
is any instance of a neutral being open in this circuit, then there
will not be a case of the loads in series with 240 volts.
But the issue I see right now is with wiring these TWO neutrals in
the panel. The catch is that the breaker will be a GFCI breaker.
It will be a 2-pole common handle type. But this means two wires
will be connected to the one neutral lug on the breaker. Can this
be done in compliance with NEC (and without using a wire nut)?
The reason this is being done on a common breaker is that this will
be going to a common box device where it will be necessary to open
both circuits at the same time if either is open.

Use a standard dp breaker w/ gfi receptacles. It is cheaper, much more
convenient if there is a ground fault.
Otherwise, use two receptacle boxes (handy boxes) to eliminate the need for
a dp breaker.

Personally, I find GFI receptacles ugly. I'll put them in the bathroom and
garage, but definitely not in the kitchen. The breaker panel won't be that
far away. And how often have you seen a GFI trip in real life? Still, the
breaker panel won't be far from the kitchen (around the corner in a closet).
I also don't like having a mix of circuits in the same box, so even if I do
go with a 2x2 outlet, it would still be on the same breaker.
