In our plant we have two 125 volt battery vaults. Both feed breaker panels.
None of the conduits leaving the breaker panels have equipment grounds
pulled in with the positive and negetive. We are feeding some switchgear
with a new conduit form one of these panels. Is it comon in a DC system
to not install an equipment ground? Or were they not installed by a contractor
to lower there bid proposal? Should we pull a ground regardless of what the
contractors did?
