Infinity pool collapse hurts customers – PoolMagazine.com

For those who are lucky enough to have a swimming pool in their residence, swimming can be a great way to relax during the summer months. While swimming pools are a great way to relax, stray voltage in the pool can pose a significant threat. Stray voltage usually occurs from improperly grounded pool equipment.

What is Stray Voltage?

Before you know how to prevent stray voltage from occurring, you need to know what it is. In most lay terms, stray voltage exists when leakage of unconstrained currents from an electrical source. When swimmers or pets come into contact, stray voltage can even be deadly.

Most first shocks from stray voltages are below 10 volts, which is not very strong. When a person enters the pool or touches a handrail or ladder connected to the pool, they may feel a slight tingling or prickling sensation. Children are more sensitive to sensory input than adults, so they often notice these little bumps before adults.

A faulty transformer or electrical cable can often be the source of stray voltage in the pool. This leakage current then passes through the ground in an attempt to deplete its energy. Much like a thunderbolt, it uses Earth’s ground as a path.

In reality, these voltages are found under the floor of most homes. Your family could be in danger even if your home’s electrical system meets all applicable standards.

Common sources:

  • Damaged or melted neutral or ground wiring systems
  • Faulty lighting systems
  • Damaged or exposed buried electrical cables
  • Faulty “drops” of overhead power cables (where power is accessible from the mainline)
  • Electrical panel problems
  • Damaged pads under transformers can also conduct stray voltage.
  • A variety of other sources

One of the most likely places to find stray voltages is in a swimming pool, simply because electric current has a much less resistant transit in the presence of water. When electricity travels from an electrical outlet to another conductive item, such as a metal water pipe, metal support beam, or concrete slab, it’s called “stray voltage.”

Until the power supply is cut off or the power supply source is removed, the electricity will remain in the water. Having poor electrical wiring, inadequate GFCI protection for outlets and circuits, and electrical cords and appliances that come in contact with water are the three most common causes electrocution in swimming pools.

Identify the source of the problem

Electrocution in a swimming pool is very rare, but it remains a risk for anyone with a swimming pool. Therefore, it is important to know what to look for if there is electrical current in the pool and how to stop it.

Previously, it was common to embed metal rebar in concrete floors (for concrete stability). Metal was the preferred conductor of electricity, rather than concrete, and stray voltage was not a major concern at the time.

Stray current became a problem as the concrete industry began to incorporate additional components into the mix and rebar was no longer required on every build. As a result, touch voltage has been associated with far too many cases of injury and even death.

There is no visible sign or way to tell if the pool water contains enough electricity to kill. Most of the time, people don’t feel the electric current right away when they enter the pool. It’s a lesson New Jersey owner James Volk learned firsthand.

“My wife, my mother-in-law and my daughter were in the pool and my wife went to clean the skimmer basket,” Volk said. source of information. “When she put her hand in it, she was so shocked that she felt it all the way to her feet, like tingling, numbness.”

The whole family learned to walk gently around the pool, as some experienced it. shocks outside the pool. The family are currently investigating the cause of the problem and have closed their pool until they can determine the cause.

Protect swimming pools from stray voltages

Protecting swimmers in the pool from stray voltage should be a top priority. With proper wiring, the risk of stray voltage can be significantly mitigated. Wiring and grounding will also work better. Therefore, examining how to stray current protection begins during the construction of the pool itself.

Stray voltage can occur suddenly if problems develop on the ground or neutral side of an electrical system. Equipment that has worked perfectly for years can malfunction if something out of the ordinary happens.

Every pool with an underwater light, a pump to move the water, or an electric heater has a chance that the water will become electrically charged in the event of a power failure. Most experts would advise adding equipotentiality grids under the pool and deck to provide stray voltage an alternate path.

A swimming pool should be electrically safe for swimming if it has been constructed correctly and has an equipotential deck surface with all its components correctly glued.

Shock Alert – ESD (Electric Shock Drowning) Prevention System

If you suspect your pool has stray voltage, a device known as a “shock alert» can be used for check electricity in pool water. If there is electricity in the water, the shock alert will let you know by beeping and flashing red. This would indicate that there is electricity in the water and swimmers should stay away. If the device is flashing green, on the other hand, that would indicate that there is no voltage and the pool is safe to swim in.

What to do if you experience stray voltage in the pool

The best advice is to avoid contact with stray voltages at all costs. Seek help from a licensed electrician as soon as possible if you think you have this problem near your pool or spa. Do not allow anyone, including humans and pets, near the pool until the problem has been resolved.

The electrical code has undergone significant evolution over the past decades. It is possible that the bonds in many older pools were never properly installed or built to begin with. A wiring fault or a problem with your electricity supplier are also additional possibilities. There are a number of potential causes of stray voltages, so it’s best to have the problem checked and repaired by a qualified electrician. Most problems have very simple solutions.
