Thanks for the input. The 12/2 is 5 years old or less. If I split the run and treat it as two 12/2 runs does it still have to be on a double pole breaker or can I use the same two 20amp breakers (opposite phase of course)?

Hello, first time poster here. I would like ask for some clarification from the "Jims" related to the shared nuetral and the gfis. Quote: Originally posted by Jim Port The neutral of the MWBC just needs to be spliced ahead of the first GFI. You would then feed xx-2 to any of the downstream receptacles. Exactly, Jim. Have done it hundreds of times. I am currenlty rewiring at my rental property (whole house) and have two separate 12/2 circuits feeding the kitchen (small) through the unfinished basement below for the two 20 amp appliance circuits. Each circuit has a gfci receptacle with a duplex receptacle on the load side of the gfci (4 countertop outlet locations total). I have come across a great deal on some 12/3 and ask the following: Can I feed the two 12/2 circuits from a junction box mounted underneath the kitchen in the basement with the junction being fed by the 12/3? (of course replacing the two 20 amp breakers with a single double pole). The run from the junction box to the panel would be the length of the house and I could save money and physical space feeding to the outdoor panel; not to mention repurpose the 12/2. If I run the 12/3 to the junction and "split" (pigtail) the nuetral at that location and continue on with two 12/2 runs, would I still need to put gfci receptacles at each location and rewire the current ones off the "load" side of the other gfcis? I hope my questions make sense and thanks in advance for any input!! Dan
