27.5 The device box within which a switch as described
in 27.4 is installed, and the accompanying
coverplate, shall comply with the applicable
standards within the UL 514 series: Metallic Outlet
Boxes, UL 514A; Conduit, Tubing, and Cable
Fittings, UL 514B; Nonmetallic Outlet Boxes, Flush-
Device Boxes, and Covers, UL 514C; Cover Plates
for Flush-Mounted Wiring Devices, UL 514D.

27.6 With reference to the requirement in 27.1, the
current rating of a switch that controls an inductive
load, other than a motor, such as a transformer or
a fluorescent-lamp ballast, shall not be less than
twice the rated full-load current of the transformer
or ballast, unless the switch is known to be
acceptable for the particular application.
N/A
27.7 A manually operated, line-connected, single pole
switch for appliance on-off operation shall not be
connected to the conductor of the power supply
cord intended to be grounded. Table 15.2 specifies
the identification of the power supply cord
conductor intended to be grounded.
N/A
27.8 A switch is considered to be acceptable for
controlling a tungsten-filament lamp load when:
a)It has a T or L rating and a current rating at least
equal to the tungsten-filament lamp load; or
b)It has an alternating-current rating at least six
times, or a direct-current rating at least ten times
that of the tungsten-filament lamp load.
N/A
27.9 A switch provided for the control of a fluorescent
lamp and not integral with the lampholder shall
have a current rating at least twice the primary
rating of the ballast. Each ballast is to be
considered as requiring its rated input current.
N/A
27.10 When an appliance provided with a direct-plug in
power-supply cord and an attachment plug
N/A
27.11 A speed-control switch shall be provided with an
appliance that employs a multispeed motor – a
motor with a winding capable of various pole
groupings.
N/A
27.12 The construction of a switch shall be such that only
one circuit can be energized at a time.
