Swimming Pool Stray and Contact Voltage Research

Electrical safety is our key concern and I'm always looking out for information that will help keep the industry safe. I wanted to pass along this report from the Electric Power Research Institute on Swimming Pool Stray and Contact Voltage. I hope you find it has value.

2018 testing by EPRI has determined that nuisance tingling sensations for swimming pool users are precursors to a swimming pool that could become an unsafe shock hazard during 120Vac household line faults. To understand this phenomenon from a scientific basis, EPRI has tested the different types of in-ground pool shell designs to include both the conductive types and the non-conductive types.

The primary objectives of the testing were to understand:
1. How and why voltage gets to the pool water and to the conductive metal parts around the pool
2. Why equipotential bonding between the pool deck and any of the other bonded parts and the water is so challenging
3. Which pool types are at the greatest risk of becoming electrically unsafe Electric Power Research Institute (EPRI)
