Bonding a plastic pool is an important process to ensure the safety of swimmers. The National Electrical Code (NEC) mandates that pool water must be electrically bonded to prevent electrocution and serious injury. This involves creating an electrical field around the pool by attaching a bonding wire to the pool's conductive components, such as the metal deck, pool equipment, and metal pool wall. Proper bonding ensures that stray currents are controlled and safely directed away from the pool area. While the process of bonding a plastic pool may vary depending on its specific characteristics, it is essential to follow local state and federal building codes to ensure a safe swimming environment.

What You'll Learn
Understanding the purpose of bonding a plastic pool
Bonding a plastic pool is essential for ensuring the safety of those who use it. The primary purpose of bonding a pool is to control electrical currents and prevent electrocution. By bonding the pool, you create a conductive path that keeps electricity from passing through swimmers, protecting them from potential harm.
The National Electrical Code (NEC) mandates that all swimming pools must have electrically bonded water. This means that the pool water must be in contact with a conductive material, creating a continuous electrical path. This helps to balance the electrical "pressure," directing currents away from swimmers and into a bonding wire or grid, where they can be safely dispersed.
In the context of a plastic pool, bonding typically involves creating a "'halo" or loop of #8 bare copper wire around the perimeter of the pool. This wire is connected to bonding lugs or screws at various points, including the pool equipment, metal deck, pool wall, and even the water itself. This comprehensive bonding ensures that anyone in or around the pool cannot come into contact with stray electrical currents.
It is important to note that the specific bonding requirements may vary depending on local regulations and the type of pool. For example, some pools may have different requirements for the number of bonding points or the distance between the wire and the pool wall. Therefore, it is crucial to refer to local building codes and consult with professionals to ensure that the bonding is installed correctly and safely.

Acquiring the right materials
Bonding a plastic pool is essential for safety, preventing electrocution and serious injury. The National Electrical Code (NEC) mandates that pool water must be electrically bonded, and this process is different from grounding the pool. The goal of bonding is to keep electricity and swimmers separate.
To bond a plastic pool, you will need the following materials:
- A skimmer bonding plate, which comes with instructions and bonding lugs.
- #8 solid bare copper wire, which is available from electrical suppliers or online. You will need enough wire to create a continuous loop around the pool, 12-18 inches from the wall, touching the water bonding plate and the pump. The exact amount of wire will depend on the size of your pool. For round pools, take the diameter and add two feet, then multiply by 3.14, and finally, add 25 feet. If you have a metal deck, consider adding another 20 feet.
- Bonding lugs, which attach the wire at every point. You may need additional hardware to attach the lugs, such as bolts and nuts or stainless self-tapping screws.
- A shovel or other digging tool to dig a trench 12 inches from the pool wall and 6 inches deep to lay the bonding wire.
- Optionally, you may need a drill to create holes for attaching the lugs and wires.
Some towns may have specific requirements, such as connecting the copper wire to the green wire in the plug outlet box. It is important to be aware of local requirements and consult with a qualified electrician or pool professional to ensure your pool meets all safety standards.

Preparing the pool and its surroundings
Firstly, it is essential to understand the purpose of bonding a pool. Bonding is the process of creating an electrically conductive path by permanently joining metallic parts. This helps control electrical currents and prevents electrocution, which could occur if a swimmer comes into contact with a different electrical potential.
Before beginning any work, ensure you have the necessary supplies. You will need a complete pool bonding kit, which includes a skimmer bonding plate, #8 solid bare copper wire, bonding lugs, and any necessary hardware for attachment. These kits are available in different sizes, so ensure you select the appropriate one for your pool size.
Next, determine the layout of your pool and its surroundings. Identify any metallic structures or equipment around the pool, such as a metal deck, pool wall, or nearby equipment like pumps and filters. These metallic elements will be crucial for creating the conductive path during the bonding process.
Clear the area around the pool and ensure you have safe and easy access to all relevant components. If there are any obstacles or hazards, remove or secure them to create a safe working environment. This includes ensuring any necessary permits or approvals are in place, especially if you are working with electrical components or making structural modifications.
Finally, carefully inspect the pool and its surroundings for any damage or defects. Look for cracks, leaks, or structural issues that may impact the bonding process or the overall safety of the pool. If you identify any concerns, address them before proceeding with the bonding process to ensure a safe and effective installation.
By following these steps, you can thoroughly prepare your plastic pool and its surroundings, ensuring a smooth and safe bonding process while adhering to safety regulations.

Installing the bonding wire
Firstly, determine the amount of #8 bare solid copper wire you will need for the project. For round pools, a simple calculation can be followed: take the diameter of the pool and add two feet, then multiply it by 3.14, and finally, add 25 feet to that number. This will give you the required length of wire. It is always better to have some extra wire than to fall short.
Now, dig a trench for the wire to be laid. The trench should be 12 inches away from the pool wall and 6 inches deep. This trench will house the bonding wire, creating a "halo" around your pool. If your pool has a metal deck, consider adding a few extra feet of wire to touch the deck in two to four spots, as recommended by some sources.
Next, attach the bonding wire to the metal components of your pool. This includes the metal pool wall, metal deck, and any other metal equipment such as pumps, filters, or lighting transformers. The wire should be attached to these components using bonding lugs. If your pool has plastic components, you may need to drill holes and use bolts and nuts or self-tapping screws to secure the lugs. Ensure that the wire is securely connected to these metal parts, creating an electrical connection.
Finally, connect the bonding wire to the pool water. This can be done by using a water bond, such as a skimmer bonding plate, which allows the wire to be in contact with the water at all times. This step is crucial, as it ensures that any stray electrical currents are safely directed away from swimmers.
It is important to note that local regulations and requirements may vary, so it is always a good idea to consult a professional or refer to specific guidelines provided by your local authorities.

Connecting the wire to pool equipment
Bonding a plastic pool is essential for safety. The National Electrical Code (NEC) mandates that pool water must be electrically bonded to prevent people and electricity from mixing.
To connect the wire to pool equipment, you will need a skimmer bonding plate, #8 solid bare copper wire, and enough bonding lugs to attach the wire at every point. Dig a trench 12 inches from the pool wall and 6 inches deep to lay the bonding wire. Drill a 3/16th hole for the bonding plate and attach the lugs using bolts and nuts or stainless steel self-tapping screws. Run the wire to all the bonding lugs, connecting to the pool frame or wall. Some towns require you to also connect the copper wire to the green wire in the plug outlet box.
For round pools, take the diameter of your pool and add two feet, then multiply by 3.14, and finally, add 25 feet to that. If you have a metal deck, consider adding another 20 feet to touch it in two to three spots. The skimmer bonding plate and the pump come with bonding lugs, so you may only need four more to connect to the pool frame or wall.
If your pool has a concrete walkway nearby, it does not need to be bonded unless it is very close to the pool. You should also ensure that any plastic ladders and ladder cups do not need to be bonded.
The goal is to create a continuous loop around the pool, touching the water bonding plate and the pump. The wire should be buried 8 inches from the surface and return to the starting point to close the loop.
