All electric wiring installed shall be installed
and used in conjunction with private residential swimming pools in
conformity with National Electric Code standards, and the materials
used or installed shall be as approved by National Underwriters' Laboratories.
No electric wires or conductors shall be installed
or permitted to remain in such a position as to cross, either overhead
or underground, any part of a private residential swimming pool, nor
shall any electric wiring be installed parallel to any pool wall closer
than five feet thereto, except if such wiring is both located underground
and enclosed in rigid conduits.
All underwater lights shall be watertight, self-contained
units, each with their own ground connection running from a waterproof
junction box to a proper grounding facility or medium. All underground
electric wires supplying current to such light or lights, within a
distance of five feet of the pool wall or walls, must be enclosed
in rigid conduits.
All metal fences, enclosures or railings which
are located near or adjacent to private residential swimming pools
and which might become electrically alive as a result of contact with
broken overhead conductors or from any other cause shall be effectively
grounded.
