Just look at a house electrical system. I need help in understanding.
The owner hired an electrician to replace the house old electrical service.
The house electrical panels are located in the basement.
The electrician installed new service wire.
The electrician installed a new single meter socket.
The electrican ran wires from meter socket inside the house garage thur a metal conduit.
The electrican installed a 100 amp. 20 space panel, with 100 amp breaker.
The electrician grounded this panel to two copper ground rods.
The electrican installed this panel on top a conduit containing three insulate copper wires. He then installed a two pole 100 amp. breaker and landed the three insulated wires, two hots at the breaker and the third
insulated wire to the panel grounded buss.
Now back at the basement panels all the grounds and grounded conductors share the same buss bar, with it bonded to the metal panel
box. This were I think something wrong. Should have the electrician installed a individual buss bar and removed the grounding conductors and
place then on a newly install buss bar. And removed the bond screw.
This panel is feed by rigid metal pipe. And could this pipe become the
forth wire, for these panels. Or is pre-existing and its okay the way it is.
Thanks.:cool:
