"Grounding balls"
"Grounding balls"
(OP)
We have a European customer (we're in Canada) who is asking for "grounding balls" on terminals in equipment rated 11 and 35 kV. These are for connection of grounding kits used during service. Has anyone heard of these? And if so, can you direct me to a standard that defines what they should be?
