How Are Swimming Pools Wired?
There are some definite electrical wiring requirements for swimming pools, and they vary from state to state. The National Electrical Code determines swimming pool wiring rules so that the pools can be used safely for recreational purposes. Professional electricians are thoroughly familiar with all required rules and regulations.
There are electrical receptacles around the swimming pools and they should always be securely covered. The convenience receptacles, which are 120 V, should be at a distance between 6 and 20 feet from the pool and the protection is by a ground fault. The wire connection to the panel from the receptacles for the pool pump or motor must be No. 12 or must be a larger copper ground wire.
There are also definite requirements for underground conductors like rigid conduits, nonmetal conduits or intermediate conduits.
It is prohibited to install a direct buried cable from the home or accessory structure to the pool. The wiring must be passed through rigid conduits like intermediate metal conduits, nonmetallic plastic conduits or PVC. The rigid and intermediate conduits must be buried at least 6 inches below grade. On the other hand, nonmetallic rigid plastic conduits or PVC require to be buried deeper, at least 18 inches below grade.
Some parts of the swimming pool are metal or have metal parts. The electrical contractors should bond together all the metal parts with a No. 8 or larger solid copper wire. Metal parts include such items as metal ladders, pump metal, the water circulating system's metal parts, metal parts of the pump, and all the fixed metal pool parts which are within 5 feet of the pool. In this way the electrical system to the swimming pool is completely safe.
