grounds [RE-wrenches]

[Allan Sindelar]

Hugh,
In our country, tying a current-carrying conductor to ground at one point is
called bonding. You then have a "grounded" conductor--the neutral, which is
current-carrying but has zero potential to ground--and a "grounding"
conductor (the bare or green), which carries current only in a fault
situation.
It's confusing also because multiple ground rods are "bonded" together, so
there can be no potential between them. Trace emphasizes bonding AC and DC
ground paths together because otherwise that potential (such as a
lightning-induced surge) fries stuff in the inverter, where both come
together.
Does this help?
