I have installed a 20 amp double pole breaker using 12/3 wire in alternating series in my kitchen. I am trying to install GFCI protection to both sets of receptacles, but I am having a problem where any outlet that is off series of the first GFCI trips the GFCI only when something is plugged in (tester works fine) (example: GFCI set to black wire, all red wire outlets trip the GFCI when used) I have tried installing a second GFCI in the alternate series with no luck. I know it has something to do with the shared neutral, but I am not sure how to correct the problem so that I have GFCI protection on all outlets. Any help would be greatly appreciated. Also let me know if I need to clarify any points

At the first GFCI receptacle you will have 12/3 in, 12/2 out to the next GFCI (other circuit) and 12/2 out to the first protected receptacle on circuit one. Connect the black from the 12/3 to the line hot side of the GFCI and a short piece (6 in) of white wire to the line neutral side of the GFCI. Connect the white wire of the 12/2 going out to the next GFCI (other circuit) to the white from the 12/3 AND to the short pigtail. Connect the black of the 12/2 to the red from the 12/3.

For the 12/2 going to the protected recptacles on circuit 1, connect the black to the load hot and the white to the load neutral.

One is to "split" the circuit at the first box and go to 12-2 as was mentioned.

The 2nd way is to use a 2 pole GFCI breaker.

The last way is to install a GFCI receptacle at each location and not use it to feed downstream.

You can not share the neutral on the LOAD side of the GFCI. You must either use a double pole GFCI breaker or separate the circuit at the first receptacle LINE side into two circuits each using there own neutral.
