Looking for advice on correcting old wiring in house without a total gut. I have 3 cables of 12/3 coming from from 6 circuit breakers going up to the attic. Each cable shares a neutral that is tied together in the attic where the hots split. None of the 12/3 has a ground. Circuits with shared neutral are opposite phases. Seems like my options for no ground are:
1- replace all wiring with wire with ground, or add ground to every box and bring it back to panel
2- add GFCI receptacles so receptacles can be 3 prong without ground
3- use GFCI breakers so receptacles can be 3 prong without ground
I would prefer option 3. However as I understand it I cannot use GFCI breaker on a circuit that is sharing a neutral with another circuit. My thought is to replace the 12/3 up to the attic with 12/2/2 (a pair of 12/2 will be tough to fish up currently). This will separate the circuits so they each have their own neutral and give me the ability to use GFCI breakers.
Am I missing anything? Any input would be appreciated.
