Changing 15 amp non-GFCI split to 20 Amp GFCI single (kitchen counters)
I have an older home and I am redoing the kitchen. The kitchen outlets are currently split ones as per the code of the day. They are presumably using 14 gauge wire. (or maybe it may be 12 since it is the 3 wire loomex) It is not practical to re-run the wire. One of them is quite close to a kitchen sink and none are GFCI. I do not have any spare breaker space in the panel for GFCI breakers, so I need to use GFCI plugs at the kitchen end. What I want to know is if this would be code:
Change out one of the ganged breakers at the panel end to 20 amp.
Connect both the red & black wires to that breaker (they are 14 gauge). This effectively increases the gauge to handle the additional 5 amps - or does it?
Install 20 amp T type GFCI outlets at the kitchen end, also common up the red & black leads.
I could install a duplex box & use 2 standard GFCI outlets, but then the top & bottoms would not be split & that is not code.
