How can big swimming pools have underwater lamps without risking to electrocute people in the swimming pool
Despite the presence of water, which is an excellent conductor of electricity, swimming pools safely use underwater lamps to illuminate the pool area. Several precautions ensure these lamps operate without electrocution risks:
- Low voltage: Underwater lamps use low voltage, typically between 12 and 24 volts, instead of the higher voltage used in household wiring. This significantly reduces the risk of electric shock.
- Isolated transformers: Transformers isolate the lamps from the power source, preventing direct current from flowing through the water.
- Sealed design: The lamps are hermetically sealed to prevent water from entering the electrical components.
- Ground-fault circuit interrupters (GFCIs): GFCIs are sensitive to small changes in current and quickly cut off power if an electrical fault occurs, preventing electric shocks.
- Depth and distance regulations: Lamps must be installed at a certain depth below the water's surface and a specified distance from the pool's edge to minimize the risk of contact with swimmers.
