Why Use Our Grounding and Bonding Products

Equipotential Bonding Explained

Equipotential bonding is the best way to create “equal voltage.” A shock, however small, is the presence of voltage differences. As the voltage differences get larger, so does the danger. The amount of voltage that can be present on a pool deck or in a pool or spa could even cause serious harm. There can even be enough to cause death.

The voltage can come from a number of sources. Most often it would be older, damaged or poorly installed electrical. The simplest way to achieve equal voltage is with correct grounding and bonding. Our equipotential bonding grid kits give you everything you need. Done right, even the smallest shocks disappear.

Correct grounding and bonding are a whole field of study just on their own. So, we simplified it. We provide pre-made kits and a catalog of individual parts. Not sure what you need? Just call us and we can help!

Is there a Code Requirement for Equipotential Bonding of Pools?

Yes, but the current 2017 version of the National Electric Code does NOT meet the minimum level of safety as determined by all labs and research agencies who have conducted testing or research, such as Electric Power Research Institute (EPRI), National Electrical Energy Testing Research and Applications Center (NEETRAC), ENERNEX, and IEEE. The current version of the Code has been tested and proven that swimmers standing on the deck or touching it while in the water can receive fatal shocks and are unprotected.

The Pool Industry association is at odds with the Utility Industry Experts on this subject. Construction methods have changed over the years, and the pool industry has taken a stance that proper equipotential bonding is a few hundred dollars of unnecessary expense. This can be seen on the APSP website. The Utility Industry and testing agency experts strongly disagree and maintain that it is only a matter of time before fatalities occur. All precautions should be taken when electricity is in the vicinity of water.

    The 2005 version of the Code required proper equipotential bonding of both the pool shell and deck, but since 2008, the requirement for proper equipotential bonding of the deck was removed. Some say it was to reduce costs and increase profit, and the industry associations have lobbied to keep proper safety requirements out of the Code.

    If you experience any level of shock on your deck, even a slight tingle, it is a clear indication of inadequate bonding and exposes a potentially fatal risk. Your pool should be safe a free from any shocking. If your pool builder can’t determine the cause and solve the problem, when Utility companies are asked to assist, they may determine your pool system is unsafe and stop serving the unsafe property with electrical power until the proper safety measure is installed. The only proven measure is to remove the existing deck, install an equipotential bonding grid of either rebar or copper, and reinstall the deck.

    Retrofitting a paver deck with a proper equipotential bonding grid, is not a huge ordeal or expense. Replacing a concrete deck, however, could bear a higher cost depending on the amount of concrete to remove and dispose.

    With the lack of proper safety, your insurance company may increase your rates or refuse to write your policy. It is best to check with your insurance and utility company before you install a pool to determine if your pool will be built with proper equipotential bonding, so that your property will not be deemed unsafe for electrical power service. Subject matter experts here at CMI are also available for consultation and can also put you in touch with the proper utility liaison if there are any questions or concerns.

    If built properly, your pool should improve your heath and provide you years of safe enjoyment. A few proper steps taken during development and construction, will eliminate cause for concern. Enjoy your refreshing and beautiful pool.

What Our Customers Are Saying:
  • Our pool heater is 17 years old and broken. Instead of replacing it with a regular gas heater, we went solar. For only a few dollars more, my original pool builder came out and installed Thermocraft Solar Panels by CMI, and now we are making our money back by not having to pay heating bills anymore! We were paying over $300/ month with the gas heater! I also feel great about "going green" and helping the environment.
