Includes primary grounding
point for the whole bungalow.
This system protects every
incoming signal line and
keeps the “clean” and
“dirty” wiring separated.
The flat copper strip
provides low-impedance
interconnections between
all arresters. This panel
can be custom designed
for specific applications.
