actually if there's only one it can be a 15a. it's a duplex outlet.

providing that there are only one circuit of wires from the panel that ends in the outlet box, and no other wires leaving the outlet box: with the power off and one hand in your pocket and the other handing a check to your electrician, watch as he will probably feed each GFCI device the LINE from the CIRCUIT BREAKER panel. do not send the LOADs anywhere. see also:
Yes, really, for exactly the reason stated: as soon as anything is powered on, on either leg of the circuit, current flows in the neutral wire. The GFCI on the *other* leg of the circuit sees that the current in the neutral wire is not the same as the current in *its* hot wire, and trips.
If you want GFCI protection on the outlets of a multiwire circuit, there are only two ways to do it: with a double-pole GFCI breaker, or with a GFCI receptacle at *every* location you wish protected, wired to the LINE side only.
That's not correct. The *other* leg of the circuit does not see the neutral because it's attached to the line side of the other gfci. There is no connection between the load neutrals of either gfci
Only if you split the multiwire circuit into two separate circuits at the first GFCI, which rather destroys the point of having a multiwire circuit in the first place.
As long as the neutrals are separated at that point, I agree it will work fine. But it's not really a multiwire circuit any more.
If you're wiring two devices in a single box from the same feed
- and at least one uses wrap-around screw terminals
- and you have sufficient wire available (about 12 inches) you can strip about an inch of insulation (leaving the copper intact) halfway down the length of the wire and wrap the copper around the terminal of the first device, then connect the second device conventionally from the end of the wire. This scheme is commonly used with wires in conduit and daisy-chained devices. The wire is run through the box without being cut. just leave a sufficient loop to connect to the device.

Doug Since the purpose of using a multi wire branch circuit; which is commonly called an Edison circuit; is to save materials and labor I don't see how using one as the home run to the panel "destroys the point."

The other advantage of a MW circuit is voltage drop. That is why they commonly serve rooms on the opposite end of the house.
