Simply put the clamp-on on the third wire neutral at the GFCI.

It does not have any impact on GFCI operation or safety issues.

If I remember correctly, in the fog banks of memory, bypassing inside the wall
service box is frowned upon by insurers and possibly violates the NEC [USA].

I'm getting old, memory stalls at times, but I remember something from the late
1950s [college days] regarding bypassing inside the wall box is NAW NAW NAW.

My HAndheld trips my GFCI breaker. I have inguired on some of the groups
specializing in electrcal information without help.
I was hoping there would be those here who have the backgrounfd in both
electrical and radio that can help.I have connected some .005uF capacitors
from the load side of the GFCI breaker to ground and instlled a clamp-on
ferrite bead aroung the neutral and hot wires. This fixed the problem but I
was told I shouldnt do this as it might effect the operation of the breaker.
