Field Installation:
Dry-Niche Submersible Luminaire. This luminaire type is intended for permanent
installation only in the wall of built-in fountains, unless accompanying installation instructions
describe additional option of installation in the bottom of the fountain. These luminaires are
designed for servicing from the rear through a passageway behind the fountain wall or, if
mounted in the bottom of the fountain, in a tunnel underneath the fountain. For the purposes
of installation, maintenance or servicing, the luminaire may include a factory-installed length
of flexible cord terminating in an attachment plug. A receptacle outlet assembly for
connection of the attachment plug to the branch-circuit may be provided as an integral part
of the niche included with the luminaire.
Wet-Niche Submersible Luminaire. These luminaires are intended to be installed in the
wall of built-in fountains, unless accompanying installation instructions describe additional
option of installation in the bottom of the fountains. They are intended for installation in a
permanently installed luminaire housing (forming shell) in which the luminaire will be
completely surrounded by water. These luminaires are marked to indicate the proper
luminaire housing or housings with which they are to be used. Luminaire housings are
marked to indicate the luminaire or luminaires with which the luminaire housings are to be
used. These luminaires are provided with a factory-installed, permanently attached flexible
cord that extends at least 12 feet outside the luminaire enclosure to permit the luminaire to
be removed from the luminaire housing and lifted to the fountain deck for servicing without
lowering the water level or disconnecting the branch-circuit conductors. Luminaires with
longer cords are available for installations with a junction box or splice enclosure located
where a longer cord is necessary to permit luminaire removal from the luminaire housing
and placement on the deck for servicing.
No-Niche Submersible Luminaire. These luminaires are intended to be installed on the
walls of built-in fountains, unless accompanying installation instructions describe the
additional option of installation in the bottom of the fountains. These luminaires are to be
mounted to a bracket and permanently secured in or on the wall, with the luminaire
completely surrounded by water. These luminaires are provided with a factory installed,
permanently attached flexible cord that extends at least 12 feet outside the luminaire
enclosure. The cord is intended to function similarly to those provided with a wet niche type
luminaire. The luminaires are marked with an identification of the mounting bracket for which
they are suitable. The mounting brackets are also marked with an identification of the
luminaires for which they are suitable.
Submersible Luminaire Special Use Type. These luminaires are intended to rest directly
on the fountain or on other surfaces within the perimeter of the fountain. The luminaires are
provided with a permanently attached flexible cord intended to terminate in a submersible
junction box or to be routed out of the fountain through conduit to a junction box.
Metal Conduit Only. A submersible luminaire housing (forming shell) that does not have a
grounding terminal is marked ―CAUTION — For proper grounding use only with metal
