When installing the ground rod what is the maximun distance from the ground rod to the secondary distribution center?
The ground rod should be as close to the distribution panel as possible to keep the grounding conductor short there by keeping the impedance low. The CEC calls for two 10 foot ground rods placed ten foot apart. If the rod can not be driven in all the way it must be bent over and buried. The rods should not be cut off as there are identification marks on the top of the rods. If the electrical inspector can not find these marks he might make you install new rods. Just allowed in the new code are grounding plates. They have to be in direct contact with exterior soil at no less than 600 mm (24") below grade. The nice part is that they can be dug in with a backhoe and then buried. No more hammering.
What is the minimum depth in feet that a grounding rod must be driven into the ground?
Ground rods in the U.S. on a residential home are 8 foot long and are driven 8 feet into the ground. The top of both ground rods should be flush or just under the surface. One ground rod is placed directly under the meter base and another one is placed 6 feet to either side. They are connected together and grounded to the meter base with the correct size ground wire based on the amperage of the serviced being installed.
What is the proper grounding depth for a rod in wet land?
The wetness of the soil has no bearing on ground rods. Residential wiring requires two 8 foot long ground rods driven flush or just below the surface of the ground. One is mounted under the meter base and the other is mounted 6 feet to either side. <<>> The CEC (Canadian Electrical Code) requires two ten foot rods placed ten foot apart for the grounding system. The top of the rods are identified by diameter and length stamped into the rods. This is to prevent cutting the rods off if rock obstructions are encountered. If the rod will not pound into the ground any further it is bent 90 degrees and buried horizontally and again bent 90 degrees up to allow the top of the rod to protrude above the ground so as a connection can be made to it. In the new addition of the code it now allows a ground plate to be used as a grounding medium. Only one plate is required as it has more surface area than two ground rods. The plate is buried a one metre deep or a minimum of 600 mm if rock bottom is encountered.
Can I use a standard electrical outlet to install a warmrail in my bathroom or do I need special wiring?
Yes, modern homes have adequate electrical outlets to allow you to do this safety. Just remember these units were design to be powered from the top entry and not the bottom. So must not be used up-side down.
How high from the floor do you install an entry light?
Standard rule, top to the fixture same height as top to the door.
Why lightning rods built on top of the buildings?
Because Lightening usually strikes at the highest point.
Where are lightning rods placed?
On top of the house or building.
What was built on top of the seattle space needle to prevent lightning?
There are lightnings rods on top to prevent lighting damage. But it wont prevent lightning itself.
What do lightning rods look like?
I lightning rod varies in size. Most are found on top of building in areas that are known to have lightning activity. They are shaped like antennas and sometime have a sphere at the top of the bar.

What are some important uses for Iron?
cars are made of ironthe rods on top of tall buildings are made from ironby a sixth grader
WHY is it placed on top of the building the ligthing rod?
Because lightning is always attracted to the highest points. Lightning rods are attached to long, insulated cables which lead down to the ground - and are anchored deep in the earth. Placing a lightning conductor at the very top of a building, almost guarantees that any strike will be conducted safely down to earth.
What happens when lightning strikes a house?
There are a number of things that can happen depending on the sercumstances, lightning takes the shortest route to the ground, so if there is a lightning rod on the roof it would travel a safe path to the ground. It can tear through the roof to find a route to the ground. It would travel in metal first before wood, as in a plumbing pipe, or a metal rain gutter.
What is the function rods?
A lightning rod (US, AUS) or lightning conductor(UK) is a metal rod or metallic object mounted on top of a building, electrically bonded using a wire or electrical conductor to interface with ground or "earth" through an electrode, engineered to protect the building in the event oflightning strike. If lightning hits the building it will preferentially strike the rod and be conducted to ground through the wire, instead of passing through the building, where it could start a fire or cause electrocution.A lightning rod is a single component in a lightning protection system. Lightning rods are also called finials, air terminals or strike termination devices. The lighting rod requires a connection to earth to perform its protective function. Lightning rods come in many different forms, including hollow, solid, pointed, rounded, flat strips or even bristle brush-like. The main attribute of all lightning rods is they are conductive.
How can you create a lightning rod?
In a thunderstorm any piece of metal that is above all other objects in the sky will act as a lightning rod. ************************************* A metal lightening rod is fixed above the highest point of a building, (as in the answer above) and a metal strip or heavy cable is connected between the rod and into the earth, so directing any lightening strike to earth and safely dispersed.
When was the seattle space needle struck by lightning?
There are actually 25 lightning rods- including the tower itself- on top of the Space Needle; though lightning storms are relatively uncommon in the Seattle area, so it is not struck very often. It was recently struck by lightning three times (May 19, 2009), and was struck three years before, in 2006.
