GFI shared neutral again

[buck33k]

As has been discussed before, we know there is no problem sharing a neutral on a 120/240 volt circuit for two GFI recepticles providing the neutral is split prior to the GFIs.

Would the same apply to 120/208 volt 3ph, three GFI circuits (recepticles) sharing the neutral? Is there something additional to consider with this voltage?

There is no difference between the two systems as far as the functioning of the GFCI.. As you've stated, it's where in the circuit that you have the devices installed.

Thanks Trevor

In a new 120/208 installation as I have described, a GFI occasionally trips. I will replace it again and look at the connected equipment.
