APPLICATIONS
Wet Location Use
Wet Locations are defined as locations in which liquids may
drip, splash or flow on or against electrical equipment. This
can include places subject to saturation with water and other
liquids such as vehicle washing areas and unprotected
locations exposed to weather.
Marine Location Use
The marine location certification, UL 1598A, is a
supplemental approval to the wet location standard that
allows the luminaires to be used in salt water environments.
The standard specifically evaluates for conditions such as
salt spray corrosion, ignition protection, UV exposure and
water ingress. (Not applicable to LEDs)
Class I:
In Class I locations, flammable gases or vapors are or
may be present in the air in sufficient quantities that they
may ignite or become explosive.
Class II:
In Class II locations, it is the presence of
combustible or electrically conductive dusts that pose the
hazard.
Division 2:
In Division 2 locations, the potential hazard is
confined in containers or in a closed system and/or the area
has positive ventilation that normally prevents the gases,
vapors or dusts from reaching ignitable concentrations.
Explosive characteristics of gases, vapors or dusts vary with
the specific material; it is therefore necessary that
equipment installed within the hazardous location is
identified for the specific group of gas, vapor or dust for
which it is approved.
Hazardous Location Use
Sceptalight fixtures are listed and approved for
‘Hazardous Location’ use in:
Class I, Div. 2 Groups A, B, C, & D
Class II, Div. 2 Groups F & G
The following information is provided as an overview of
Hazardous Location environments only. Refer to the NEC for
the complete requirements of Hazardous Locations.
The determination of a Hazardous Location (Class and
Division) is the responsibility of the project engineer just as
it is the installer’s responsibility to be both knowledgeable
and certified to perform work in hazardous locations. Always
consult with the local electrical inspection authority
regarding appropriate use and installation of products.
Hazardous Locations are areas classified according to the
nature of the hazard and divided into divisions that further
define the potential hazard based on conditions that exist.
