Hello I have a 3 wire overhead line coming from the house which comes from the service on its own 70 amp disconnect.
The garage had fuses and now has a breaker panel, so I have the two hots and the neutral/ground coming into the box from the service disconnect.
The neutral bus has the ground from the service, and there is an optional lug to bond the neutral bus and ground together.
I assume I use the lug when I have an old 3 wire service coming in but I was not sure.
If the housing wiring gets redone and changed to a 4 wire garage service do I separate the two and run a wire (green) to the ground bus and a wire (white) to the neutral bus?
Part 2
The garage did not have any sort of grounding actually running to the ground so I have bought two 8 foot grounding rods and #6 bare wire to run from the rods to the ground bus in the panel.
Are there spacing requirements for separating the two grounding rods from each other?
Do they have to be driven into the ground vertically or can I dig two trenches and lay them horizontally next to the slab?
