3.2.7 Grounding the protection box
Grounding is essential for protection
against hazardous voltage as well as for
system operation integrity. For best
grounding, provide the shortest path
possible between the protection box and
the grounded structure.
1. Drill and tap a hole in a grounded
structure. Make it as close as possible to
the 6mm (1/4’’) hole in the bottom of the
protection box.
2. Fasten the AWG #8 copper wire to the
structure according to
“Fastening the ground wire to grounded
structure”
