The sole purpose of an equipotential grid is to create an area with no significant difference in voltage between objects that can be touched simultaneously. An equipotential grid is created by intentionally connecting all these objects together electrically, otherwise known as bonding them together.
What is equipotential bonding used for?
Equipotential bonding serves the purpose of ensuring that the earthed metalwork (exposed conductive parts) of the installation is connected to other metalwork (extraneous conductive parts) to ensure that no dangerous potential differences can occur.
Does my pool pump have to be bonded?
Locate the external bonding lug on the pump motor. The bonding lug is a pressure wire connector with a screw to secure the bond wire.
What is pool deck bonding?
Bonding is the process by which the electrical and metallic components of the pool are joined together with a wire to form a non-resistive path between the components. The goal of bonding is to connect, contain and prevent the transmission of any harmful electrical voltage to pool equipment, people and pets.
What is bonding jumper in electrical?
A bonding jumper is a reliable conductor to ensure the required electrical conductivity between metal raceways required to be electrically connected.
What is the main purpose of bonding?
The purpose of bonding is to establish an effective path for fault current that, in turn, facilitates the operation of the overcurrent protective device. This is explained in National Electrical Code Articles 250.4(A)(3) and (4) and 250.4(B)(3) and (4).
What is the main purpose of bonding OSHA?
The purpose of grounding and bonding is to keep that from occurring, by providing a conductive pathway between transfer and dispensing containers and the ground. Grounding all containers to an earth source is recommended to prevent the buildup of static electricity.
What happens if pool is not bonded?
If you do not bond your pool equipment there is the risk that the equipment itself will become the anode in a galvanic couple with other metal components in or around your pool. If this happens, the anode metals will deteriorate at an advanced rate, a phenomenon called galvanic corrosion.
How do you know if your pool is bonded?
Look for an exposed copper wire attached to the motor and pumps, going into the ground. It should connect in a similar way as in the image to the left. If you live in a municipality, you can also contact the building and inspection department to see if your pool had a code inspection during its construction.
Why do people bond above ground pools?
Why do you have to bond an above ground swimming pool? Bonding your pool is a safety measure to prevent accidentally getting electrocuted or seriously injured. You need to create a field around your swimming pool by attaching the bonding wire to the metal deck, pool equipment, metal pool wall, and even the water.
What is the equipotential bonding grid for swimming pools?
For the perimeter surfaces, the equipotential bonding grid is to extend under paved walking surfaces for 1 m (3 ft) horizontally beyond the inside walls of the pool unless separated from the pool by a permanent wall or building 1.5 m (5 ft) or more in height.
What are equipotential bonding requirements?
Equipotential Bonding Requirements Bonding requirements are an important and unique protective method employed to increase the safety of the users of bodies of water such as pools, spas, and hot tubs. Bonding connects the conductive elements of the pool structure, nearby metallic objects, and electrical equipment enclosures together.
How big is an equipotential grid?
A 2 by 100 foot grid, and a 3 by 100 foot grid. Each equipotential grid size comes with the exact amount of clamps and metal stakes needed for installation. So you don’t need to worry about shopping around for extra parts.
What is an Earthed Equipotential zone?
An earthed equipotential zone is one within which exposed conductive parts and extraneous conductive parts are maintained at substantially the same potential by bonding, such as that, under fault conditions, the difference in potential between simultaneously accessible exposed and extraneous conductive parts will not cause…
