This is the 200 Amp junction box that feeds the Woodshop and House Panels from the Generator. It has a 3/4-10foot ground rod with a #4 ground wire.

A series of photos showing the effort to remove the Sarah Spencer from her grounding near the Southwestern Sales dock in Windsor Ontario.
After a grounding lasting four-ish months, the 787 is back in action, which must be a relief for a whole lot of people. N20904 was delivered to United Airlines in September of 2012, last year.

Yesterday I took a trip up north to visit Glen Lethnot. It's the Angus glen that not many people know about as it's not sign posted and the route to get there follows mostly a maze of back roads from Brechin.
About 3-4 miles from the beginning of the walk we crossed this bridge and anyone who's familiar with my photostream knows I like bridges so I had to stop and photograph this one before we moved on.

Here is where the grounding tabs will sit when all is said and done. Eight should be plenty; I only have need of two right now.

Enjoying a beautiful day at Milltown State Park, Bonner, Montana. This park is at the confluence of the Clark Fork and Blackfoot rivers.
If you look at where electricity comes into your house, you'll notice 3 wires. Since the grounding is done with a pipe at your house, why do you need three?
It turns out that most of the plugs in your house connect a "hot" wire (usually colored black) to the device, and a "neutral" wire (usually colored white) as well. In the hot wire, the voltage is 120V AC, which varies from zero to a maximum 60 times every second. By putting these two wires on, current will flow in the device and switch direction as the voltage in the hot wire does.
The neutral wire is inherently safer, because it's at the same voltage as the ground and a person. If you accidentally touch a hot wire, you'll get shocked because of the voltage difference. If you accidentally touch only a neutral, nothing will happen.
Thus, we wire switches to devices in the hot wire. This means when it's off, nothing in the device is energized. If we put the switch in the neutral, stuff inside could still be at high voltage and dangerous if we touch it.
A good discussion of the safety benefits of polarized plugs can be found in this thread:

The other wire, seen at the bottom of this board, is also hot. But it's the mirror image sine wave. Half the outlets in your house are wired between neutral and one hot, and the other half between neutral and the other hot.
You also can get 240VAC by wiring a device across the two hot wires. Note that this is different than the 240VAC you get in other countries, where you have one hot and one neutral (Seen at right in this photo.) The device may work, but if having a neutral wire is essential for safety then you won't have it.
On the next picture you'll see a common 240V plug found in older buildings in the United States. One of the pins is wired to neutral and the other two to the opposite hot wires. A more modern outlet has replaced this that has a separate grounding pin.
Heres to Summer Dear Friends...There is ALWAYS something to look forward to...
As you know we are going through a lot of annoying and harrassing stuff with a neighbour right now who has become world wide known as the Troll!
No matter what he says or does....Fluffy and i will win the day...of that we are sure...and we thank you so very much for your love, prayers and support...

A Travis AFB crew chief executes grounding and bonding to prevent electron static charges before a refueling operation on a KC-10 Extender, June 10, 2016. This provides a conductive path to equalize the potential between the fueling equipment and the aircraft. The bond shall be maintained until the fueling connections have been removed, thus allowing separated charges that could be generated during the fueling operation to reunite.

I wanted to add some quick-connect tabs to my grounding plate, but mounting them was a bit tricky and real estate was limited. The solution I ended up with was breaking the forest-of-tabs into two pairs, and blind riveting each into place from the bottom side. To clear the battery tray beneath this part, the holes had to be countersunk and I'll have to use CS4-4 countersunk blind rivets.

This poster caught my attention the first time I saw it. The movie looks promising too (if only I spoke French...)

After a long grounding, Fairey Swordfish LS326 is back in the air in the hands of the Fleet Air Arm Historic Flight. The aircraft was grounded in 2000 with corrosion in the wing spars, followed by engine problems, but returned to the skies in late 2010.
