Electric Insulation, mef.nJ and "mef.nx*mef.Jx+mef.ny*mef.Jy+mef.nz*mef.Jz"

Hello,

I am trying to use the "Electric Insulation" under the "Magnetic Continuity" node to define an isolating boundary within my geometry.

When comparing the computed currents through the boundary via the Integration of

1) mef.nJ
2) mef.nx*mef.Jx+mef.ny*mef.Jy+mef.nz*mef.Jz

I would expect both results to be zero.
Unfortunately, only case 1) results in Zero.

Why is there a difference?
How can I define an isolating boundary within my geometry?

Thanks in advance
