Proper NJ swimming pool design and maintenance protect users from electric shock. To start with, be sure that the necessary electrical equipment, such as transformers, are in place. These electrical components should be placed at a safe distance from the pool to avoid direct contact with water, typically behind some bushes or tall plants.
According to ABC News, a transformer can downgrade the standard 120 volts surging through electrical equipment to just 12 volts. This is a bit stronger than a 9-volt battery but hardly life-threatening.
