Grounding is one of the most confusing and misunderstood aspects of the grid.

What does GROUND mean?
In this video we look at different types of ground symbols you may see and why we use different ones. We talk about Earth ground, chassis ground, a generic ground, analog and digital grounds.

There is a huge difference between grounding and equipment safety bonding often called earthing(the green wire)
The planet earth DOES NOT dissipate energy from a faulty in a piece of equipment. Voltage on the equipment safety bond(often called an earth) is trying to return to its source in this case a generator NOT the planet earth

Any power system needs ONE ground stake only. More grounding stakes DOES NOT make it safer, in fact having more than one grounding stake in a system increases your chances of damage to equipment by a near by lighting strike as it gives a path of least resistance thru your cables and equipment as the lighting strike dissipates into the earth.
When lighting strikes it dissipates out in a circle from the point of the lightning strike. Imagine a dart board center is where the lightning strikes and the outer 1point ring is where the energy has full dissipated into the planet earth. If you have a ground rod at the 9point ring close to center and the strike and another rod at the 2point ring, energy from the lighting strike at center will flow thru your cables and equipment as the path a least resistance instead of flowing thru the earth as is dissipates and this will cause damage to your equipment

There is alot of misunderstanding out there even among licensed electricians on the difference between grounding and electrical safety bonding often called earthing(the green wire), they are different things

Here we go over the reasons behind why neutral and ground wires are separated in sub panels. I also simulate what happens if you leave the neutrals and grounds bonded with a bonding screw or strap and where the current goes within the grounding system in a bonded neutral scenario.
