Eaton solutions for UL 508A and NFPA 79
The changes in UL 508A and NFPA 79 impact the design and
construction of your equipment. Important modifications concern
major safety issues, the disconnect means and the interlocking
of the enclosure door.
The disconnect shall be operable independent of the door position.
The disconnect must be operable, by qualified persons,
independent of the door position without the use of accessory
tools or devices.
Note: NFPA 79; Paragraph 5.3.3.1 (5) T.
An operating mechanism for the disconnecting means shall be
operable independent of the door position without the use of
accessory tools or devices.
Note: UL 508A; Paragraph 66.6.3 c.
The disconnect means is not closable with the enclosure door open,
unless an interlock is operated by deliberate action.
The interlocking means shall fulfill the following requirement:
Prevent closing of the disconnect means while the enclosure
door is open, unless an interlock is operated by deliberate action.
Note: NFPA 79; Paragraph 6.2.3.1.2.
The disconnecting means is not closable with the enclosure
door open, unless an interlock is operated by deliberate action.
Note: UL 508A; Paragraph 66.1.5.

Operable independent of the position of the door
Door closed: operation with the
external handle through the door.
Operated by a deliberate action
Door open: It is necessary to push the
handle from OFF to ON. This deliberate
action permits the operator to turn and
switch ON. This action is necessary as
in most cases there is no padlock on
the switch when somebody opens the
door of an enclosure.
Push
Door open: A robust optional kit with a
handle directly fitted on the shaft of the
switch allows the operation when the
door is open.
ON to OFF action permits the operator
to turn and switch ON. That is a major
safety issue; switching ON directly
without any other action is extremely
dangerous. The use of a padlock does
not comply with the request of the
standard; when the panel door is
opened, there is generally no padlock,
and anybody can turn the switch ON.
