Breaking tab off netural side in recep.

Is it a safe and good practice to break off netural tab in recep. I have to separate circuits in one recep. My newly installed gfi keeps tripping. I am speculating the gfi sences a leak in netural.

Are you saying the single receptacle has two different neutrals associated with different circuits? Give us a step by step breakdown of your wiring.

ray look at my thread I posted on 7/14/2010 about gfi keeps tripping.

I see no reason not break off the tab if the neutrals are serving different circuits. In fact, if that is the case, it is required. Neutrals of different circuits should never be connected together unless they are part of a multiwire circuit.

In what scenario would you run two entirely separate circuits to a duplex receptacle? Why not just feed it with a MWBC and keep the neutral tab intact?

That is normal pratice to run the MWBC but a clevat is with current code you have to use legit two pole breaker on this one.

Older home can get very tricky if not carefull with both line and netrual conductors on the switch or receptale box.

Merci.

Maybe when you don't have any 12-3 handy. You also might not want to risk floating voltage of a broken neutral which is a possible side-effect of MWBC. You generally wouldn't want to run MWBC to a computer room because harmonics in the neutral can cause overcurrent.

Ibpooks .,

The harmonics is not very serious affect on single phase load but on triphase yeah if used common netural but seperated netural not a major issue beside the switchboard that will be a issue if not addressed.

Thanks for the input....i am going to break off neutral tab and this will solve issue of gfi tripping.
