Ground fault [RE-wrenches]

[Jeffery Wolfe, Global Resource Options]

Actually, if it is so important, shouldn't we be considering it on all AC
equipment as well? Anything that could have a short in it but remain powered
at a lowered level, however remote the chance?

Christopher,

Your comments suggest that nothing will prevent some problems from
occurring, if GFIs and fusing aren't able to provide protection. In over 20
years of installing battery-based power systems, I've never installed a GF
protection device at the PV or battery primary wiring, seen one installed by
anyone else, or seen any damage as a result of not installing one. Not to
say it isn't possible (as evidenced by William Millers problem system) but
for this occurrence to trigger mass installations of ground fault
protectors, which are problematic in themselves, seems a little on the
reactionary side, nes pas?

If this issue is so all-fired important, why not include ground fault
protection in and for ALL DC control and conversion devices as standard,
from the factory? Hmmmmm?---
