Pools that clean themselves provide a convenient for homeowners to keep the surfaces looking. They help save time and energy. The systems use jets to push debris into the skimmer, which the dirt out. This makes it easier to remove algae that typically builds up in stagnant areas of the pool. In-floor pool cleaning systems are designed to clean areas that skimmers miss.
It is common for swimming pool contractors to recommend installing a panel close to where the majority of the equipment is located. This is designed to save costs while complying with local and state codes. Running raceways to the pool equipment necessitates the use of additional material and contributes to higher labor costs. The installation of wet niche lighting allows pool users to enjoy a swim at night. The feature illuminates the water.
Key considerations
Apart from regulatory requirements, the need for a bond is also influenced by pool location, earthing arrangements, location of electrical equipment and pool construction method. Some of the risks associated with electrical installations on swimming pools are wide-ranging. Risk of contact with earth’s conductive mass is one of the major considerations. The conductive mass may be at different potential compared to the earth of the pool’s electrical system.
The reduction of body resistance due to wetness increases chances of an electrical shock. The same applies to the possibility of pool users getting in contact with earth’s potential. As such, the installation design needs to incorporate a suitable earthing arrangement to counter external influences to the system.
Contractors use different types of earthing arrangements on domestic and commercial premises. The TN-C-S (PME) earthing arrangement is now widely installed on domestic premises. Few TT supplies make their way to predominantly rural areas. Earthing arrangement information is typically displayed on the meter. If unavailable, the contractor will determine the applicable arrangement by examining the equipment.
Bonding
The requirements are aimed at eliminating voltage gradients in pools that clean themselves. The difference of potential is prevented by bonding around the pool area and in particular the metal parts. The difference can occur when there is an electrical fault. The bonded area is referred to as an equipotential plane.
The bonding requirements apply to metallic equipment located 12 inches on the edges of the swimming pool. The same applies to equipment that is used to service the pool. The procedure is aimed at interlocking metal parts. The swimming pool parts include motors, steps, metal fences, driving boards and various other components featured within 12-inch range of the edges.
