It is a ground cable. It completes the ground between the hot and cold water pipes. The ground path through the water heater might not be complete. This cable will make sure there is a ground path between hot and cold water pipes.
Why are my hot and cold water lines connected?
A defective mixing valve will allow a cross-over of hot and cold water, even though there are no visible signs of trouble or leak. A plumbing cross-over can cause a complaint such as ‘water not hot enough’. Testing the hot plumbing system for a cross over can be accomplished by using the following procedure: 1.
Why is there a ground wire on my waterline?
The main purpose of this bond is to make sure that the metal water pipe is not affected by the service grounded conductor. If the metal water pipe becomes energized, there is a path back to the service for electrical current flow.
What is a bonding wire on a water heater?
The bonding wire is intended to allow that faint current between the water pipes to bypass the copper-to-steel fittings and thereby prevent corrosion caused by electrolysis.
How do you bond hot and cold water pipes?
Quote from the video:
Quote from Youtube video: Line the cold water and the hot water okay and um mine doesn't have this but sometimes there's a dielectric. Between these two and you have to do it above.
Do water pipes need to be grounded?
The NEC requires that water pipes be bonded to ground, even if these metal pipes are not used as part of the grounding system.
Should house plumbing 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 a bond wire?
Definition of ‘bonding wire’
A bonding wire is a wire connecting two pieces of equipment, often for hazard prevention. To bond two drums, a bonding wire must be used, which is a copper wire with alligator clips.
What is pipe bonding?
The main purpose of this bond is to ensure that the metal water pipe is at the same zero voltage to ground as the service grounded conductor. A secondary purpose is to ensure that there is a path back to the service for electrical current flow if the metal water pipe becomes energized.
Does water pipe have to be bonded?
As long as the Water pipe, Gas pipe or Oil pipe, coming into your property are metallic, Main Bonding is compulsory in all circumstances even when the rest of the pipes in your house are plastic.
Is earth bonding still required?
Supplementary equipotential bonding (between waste pipes, metallic service pipes and earth connections of bathroom equipment) is no longer required if, and only if, the main bonding between metal service pipes can be proved to be continuous.
Where is main protective bonding found?
The protective bonding connection is required to be located as close as practicable to the incoming point into the building, preferably within 600 mm and before any branch pipework.
What needs bonding in a house?
Why do I need protective bonding? If you have metal water and gas pipes coming into your home – these are typically found in older homes. Protective bonding is an essential requirement of every electrical installation, however it is often overlooked by an unqualified person attempting electrical work themselves.
How do I know if my water pipe is bonded?
To find out if your electrician has carried out earth and bonding correctly, take a look at your main gas meter. You should see a green and yellow 10mm Cable attached to it. (its about the thickness of a biro pen). In addition, also take a look at your main water stopcock, you should see a similar connection.
How do you bond a water pipe?
Quote from the video:
Quote from Youtube video: Need not be connected to the protective equipotential bonding. So the simple answer is no this pipe does not require bonding.
How do you install bonding wire?
Quote from the video:
Quote from Youtube video: So what we have here is a grounding rod clamp. So what this is going to do is it's going to clamp onto our grounding rod making a secure connection between our grounding rod.
What is 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.
What happens if cable is not grounded?
A cable not properly grounded can have high electric potential when compared to the utility ground in a house. Grounding the cable system to the same ground used by the utility minimizes voltage that could exist between them.
