You may be able to use the old steel pipe, if the resistance to ground is less than 25 ohms. Mike Holt has a good article that explains how to measure ground resistance. If the resistance to ground is greater than 25 ohms, you’ll need a new ground electrode or additional ground electrodes.
Can ground wire be connected to water line?
Never ever connect an appliance green ground to a water pipe. If you need a better ground, run a heavier green wire back to the common on the electric panel.
How do you connect a service panel to the ground?

How do you attach a ground to a water pipe?
Quote from the video:
Quote from Youtube video: You want to ensure that the hook side is down and going with gravity. So if it was the hang there. We could hang that on its own with no problem. Now we're just going to tighten up the screws.
Where should I ground my main electrical panel?
Second, the main electrical panel must be grounded to a grounding electrode such as a ground rod or rods driven into the earth near the foundation of your house.
Can you ground panel to water pipe?
The NEC requires that at least one additional electrode be installed when using water metal pipes as an electrode. The NEC requires that water pipes be bonded to ground, even if these metal pipes are not used as part of the grounding system.
How do you install a ground bar to the main panel?
Quote from the video:
Quote from Youtube video: Line up your three holes on the ground bar. Two of them on the nubs. And one of them right above the hole for the screw. And put this screw into the ground bar.
Can ground and neutral be on the same bar?
The answer is never. Grounds and neutrals should only be connected at the last point of disconnect. This would be at main panels only.
Can you tie neutral and ground together?
No, the neutral and ground should never be wired together. This is wrong, and potentially dangerous. When you plug in something in the outlet, the neutral will be live, as it closes the circuit. If the ground is wired to the neutral, the ground of the applicance will also be live.
What happens if panel is not grounded?
Without a grounding wire, the circuit breakers on your electrical panel board may not work properly. Circuit breakers will trip if there’s a fault in the system. For example, if a wire were to come loose and touch a metal enclosure, like a mixer or toaster, that metal enclosure would become live.
Does a subpanel need to be grounded to the main panel?
Most panels come with a bar joining the two, which is easily removed. Code requires subpanels to have a ground connection that’s independent of the main panel’s.
Why do you have to bond the neutral and the ground wire in the main panel?
With ground and neutral bonded, current can travel on both ground and neutral back to the main panel. If the load becomes unbalanced and ground and neutral are bonded, the current will flow through anything bonded to the sub-panel (enclosure, ground wire, piping, etc.) and back to the main panel.
Why water pipe grounding is not recommended?
Even if the pipes are continuous when you install the ground wire, you can’t guarantee that the integrity of the ground would be continuous in the future, say, after a section of galvanized iron or copper pipe has been repaired with PVC. It’s not worth risking someone’s life.
Does a water main need to be grounded?
Answer: Most electrical codes require a home’s electrical system to be grounded through the copper or galvanized-iron water supply pipes that lead from the water main to your faucets. This is done by clamping the ground wire from the panel to a pipe.
What is the difference between grounding and bonding?
Bonding is the connection of non-current-carrying conductive elements like enclosures and structures. Grounding is the attachment of bonded systems to the earth. Both are necessary to safeguard people and property from electric hazards.
Do I need ground for electric water heater?
Does a Water Heater Need to be Grounded? A water heater does not need to be grounded, though. It is recommended. Using a bonding wire to ground the cold and hot water pipes to the home help prevent pipe corrosion and the steel water heater.
How does this buried ground wire keep your house safer?
The solid mass of earth below our feet has a negative electrical charge, which means positive electrical charges are naturally attracted to it. A ground wire helps those positive charges get to the ground in a safe, direct and controlled way, where they can be discharged without the risk of electrical shock or fire.
Why is there a ground wire on my water heater?
Plumbing System Grounding
The water heater creates a break between the cold water pipes and the hot water pipes in the home. By bonding the hot water pipe to the cold water pipe at the water heater, it is thought that this helps to ensure that the entire plumbing system will be electrically grounded.
How do you ground a water heater?
Quote from the video:
Quote from Youtube video: And one thing now this is not in all codes by the way but in some states that's required some it isn't but it's a good idea and it's pretty cheap insurance. These codes require that there be a ground
Do water lines need to be grounded?
Answer: Most electrical codes require a home’s electrical system to be grounded through the copper or galvanized-iron water supply pipes that lead from the water main to your faucets. This is done by clamping the ground wire from the panel to a pipe.
Why do water pipes need to be grounded?
Historically, the home’s copper water pipe system provided a safe ground for the home’s electrical system. The plumbing system was grounded because its metal pipes extended a long way underground. Changes in the way homes are plumbed required adaptations in the way installers ground plumbing systems.
Where do you bond a water pipe?
Main Bonding (Earthing)
Connections are made on the metal pipes near the point at which they enter your home, i.e. The Main Bonding for the water is normally connected within 600mm of your Water Stop Tap. Main Bonding is there to protect you.
Is earth bonding a legal requirement?
As of 2008, earth bonding is a legal requirement for any electrical installations in rooms that contain a shower or bath. The term ‘earth bonding’ refers to the use of a thick green and yellow copper cable to connect your gas meter or consumer unit to incoming supplies such as your gas pipe.
Where do you connect earth bonding?
Quote from the video:
Quote from Youtube video: Size for a TNCs system the size of the main bonding conductor is based upon the size of the supply combined in neutral earth conductor or penka daughter.
