Stray voltage in and around swimming pools is a concerning issue that pool owners should be aware of. Stray voltage refers to an electrical current that is present where it should not be, which can cause serious harm or even death if not handled properly.
There are several causes for stray voltage in swimming pools, including faulty wiring, improperly grounded equipment, and damage to the pool’s underground electrical system. These issues can occur when the pool is being installed, during regular maintenance, or as a result of natural wear and tear on the pool’s components.
If you own a swimming pool, it is your responsibility to make sure that proper safety measures are in place to reduce the risk of stray voltage shocks. In this blog post, we will share some shocking facts about stray voltage and provide helpful tips on how to mitigate it in and around your swimming pool.

Understanding Stray Voltage
What is stray voltage?
Stray voltage refers to the presence of a small amount of electrical current that flows on surfaces, conductors, or devices at a low voltage level. This can occur due to various reasons like improper wiring, equipment malfunction, and lack of maintenance.
Although it is not always dangerous, stray voltage can pose a significant threat if it exceeds safe levels. It can lead to electric shocks, fires, and even electrocution in severe cases.
As swimming pools are typically wet environments with several electrical appliances and pumps, it is crucial to mitigate stray voltage risks for swimmers’ safety.
How does stray voltage affect swimming pools?
Swimming pool water contains many dissolved minerals such as chlorine and salt, which make it an excellent conductor of electricity. If any electrical leakage occurs from faulty wires or fittings in and around the pool surroundings, the water may act as a conductor, and these charged particles will begin moving towards anything grounded near the pool.
When you come into contact with the electrified object while standing in the pool, you could experience tingling sensations, muscle spasms and sometimes, cardiac arrest. Therefore, mitigating potential stray voltage problems inside and around a swimming pool remains essential for ensuring swimmer’s security.
To prevent harm caused by stray voltage, the authorities recommend taking precautions such as installing ground fault circuit interrupters (GFCIs), using non-conductive materials, hiring qualified electricians and performing regular maintenance checks on all electrical systems.
Identifying Stray Voltage
Signs of stray voltage in and around swimming pools
If you or your loved ones experience any tingling, burning, or shocking sensations while touching metal objects in or near a pool, it may be a sign of stray voltage. Some other signs that can indicate the presence of stray voltage are discolored water or stains on the pool surface caused by electrical corrosion.
In some cases, lights flickering or dimming when certain appliances are turned on is another indication that there could be an issue with stray electricity.
If any of these signs are present, immediately turn off all electrical devices that may be contributing to the problem and call a licensed electrician for further assistance.
How to test for stray voltage
The best way to test for stray voltage is with a multimeter, which measures voltage levels between two points. To start the testing process, first, ensure everyone is out of the pool, then turn off all electrical devices in and around the pool area.
Next, place the probes from the multimeter into the water at different points around the pool to measure any voltage present. If there is more than about 0.1 volts recorded, this may indicate the presence of stray voltage.
It’s also essential to check all electrical equipment and wires connected to the pool, such as pumps, heaters, and lighting fixtures, for any damage that might cause stray current flow. By identifying and repairing any damaged areas, owners can help mitigate the risks of stray voltage in and around swimming pools.
Preventing Stray Voltage
How to Properly Ground Pool Equipment
Grounding your pool equipment is an essential step in preventing stray voltage from occurring. Here’s how:
- Always follow the manufacturer’s instructions for grounding.
- Use only properly grounded outlets or cords for all electrical devices.
- Avoid installing any electrical device if you are not certain of proper grounding.
Installing an Equipotential Bonding Grid
An equipotential bonding grid helps prevent electrical shock in swimming pools by eliminating differences in electrical potential between conductive surfaces like metal fences and ladders. Here are some steps to installing one:
- Plan out a grid layout that covers the entire area around your pool, including ladders, lights, pumps, and other metal fixtures.
- Connect each metal fixture with a heavy copper wire, then bring them all back to a central grounding rod.
- Ensure that the bonding grid is correctly installed and tested before filling the pool with water.
Regular Maintenance and Inspection
Maintaining and inspecting your pool’s electrical wiring regularly prevents many potential problems. Here are some tips for regular maintenance and inspections:
- Inspect electrical equipment, such as pumps and filters, annually.
- Check connections for wear, damage, and corrosion periodically.
- Have an electrician test the pool, bonding grid, and its components every few years.
Dealing With Stray Voltage
What to do if you suspect stray voltage in your pool
If you suspect the presence of stray voltage in your swimming pool, it is important to take immediate action. One of the first things you should do is to turn off all power sources to your pool area and refrain from using any electrical equipment until a qualified electrician has assessed and rectified the problem.
You may also want to consider conducting a volt test to confirm whether there is indeed an issue with stray voltage or not. A volt test involves measuring the amount of electricity present in the water around your pool.
In case the tests show high levels of stray voltage, then you need to act on it quickly since it poses grave danger to anyone who comes into contact with the water. Failure to address this situation can lead to serious injuries or even death due to electrocution.
Contacting a qualified electrician
The only way to ensure that stray voltage is mitigated effectively is by contacting a professional electrician with experience in handling cases like yours. These professionals have the skills and tools to diagnose the extent of the problem and offer effective solutions within no time.
If you attempt to handle the situation yourself, you expose yourself to great risks because stray currents are invisible and can occur when least expected. By engaging an expert, you will be assured that they know exactly what to look out for when attending to such issues.
We strongly advise against DIY repairs as they are risky and could exacerbate the situation. Remember, always put safety first!
Importance of Pool Safety
Aside from ensuring that stray voltage is kept at bay, it’s necessary to practice pool safety measures to safeguard people using your pool. Never overlook simple steps like ensuring all equipment used in the pool is water-resistant and correctly grounded.
Cover open electrical boxes with weatherproof covers to prevent rainwater from entering them. Conduct regular inspections on all electrical wiring around your pool area, including those connected to underwater lighting systems, and have any faults fixed immediately.
Always remember that when it comes to pool safety, “better safe than sorry” should always be your guiding principle. Take every precaution possible to keep everyone who uses your pool free from harm.
