28.7
A switch provided as part of a power supply shall be acceptable
for the maximum potential to ground of the circuit. A nominal
208-volt, single- or 3-phase, or a 120/240-volt, single-phase
product is considered to involve a potential to ground of less
than 150 volts. A 2-wire, single-phase or a 3-wire, 3-phase
product with a rating in the range from 220 - 240 volts is
considered to involve a potential to ground in excess of 150
volts.
N/A
Exception: A2-wire, single-phase or a 3-wire, 3-phase product
with a rating in the range of 220 - 240 volts may be connected
to a supply circuit having a potential to ground of 150 volts or
less if marked as described in 61.1.12.
N/A
28.8
If unintentional operation of a switch results in a risk of injury to
persons, the switch shall be located or guarded so that such
operation is unlikely.
Not such construction
N/A
28.9
The actuator of a switch may be guarded by recessing, ribs,
barriers, or the like.
N/A
28.10
An on-off switch shall have a marked "off" position so that the
operator can readily determine by visual inspection when the
power unit is de-energized.
Not such construction
N/A
Exception No. 1: This requirement does not apply to a switch
complying with 28.6.
N/A
Exception No. 2: The on-off switch may be marked with both of
the symbols in Figure 28.1 in lieu of the marked "off" position.
N/A
28.11
A switch shall not disconnect the grounded conductor of a
circuit.
N/A
Exception No. 1: The grounded conductor may be
disconnected by a switch that simultaneously disconnects all
conductors of the circuit.
N/A
Exception No. 2: The grounded conductor may be
disconnected by a switch that is so arranged that the grounded
conductor is not able to be disconnected until the ungrounded
conductors of the circuit have been disconnected.

Overload-Protective Devices
P
29.1
A protective device, the intended functioning of which requires
renewal, replacement, or resetting, shall be accessible:
Fuse are used and does not
require replace by the user
P
a) From outside of the enclosure; or
N/A
b) Behind a hinged cover (see 7.5.2).
N/A
Exception: A protective device that is unknown to the user
because of its location and omission of reference to the device
in the operating instructions, circuit diagrams, and other
instructional materials provided with the power unit is not
required to comply with this requirement.
N/A
29.2
With reference to the requirement in 28.1, a control-circuit fuse
is not considered to require renewal as an intended function
provided the fuse and the load are contained within the same
enclosure.
N/A
29.3
A circuit breaker connected in the input circuit shall open all
ungrounded conductors.
No circuit breaker
