JUMP TO FULL CODE CHAPTER

1926.405(j)(4)(iv)(A)

Stationary motors having commutators, collectors, and brush rigging located inside of motor end brackets and not conductively connected to supply circuits operating at more than 150 volts to ground need not have such parts guarded. Exposed live parts of motors and controllers operating at 50 volts or more between terminals shall be guarded against accidental contact by any of the following:

1926.405(j)(4)(iv)(A)(1)

By installation in a room or enclosure that is accessible only to qualified persons;

1926.405(j)(4)(iv)(A)(2)

By installation on a balcony, gallery, or platform, so elevated and arranged as to exclude unqualified persons; or

1926.405(j)(4)(iv)(A)(3)

By elevation 8 feet (2.44 m) or more above the floor.

1926.405(j)(4)(iv)(B)

Where live parts of motors or controllers operating at over 150 volts to ground are guarded against accidental contact only by location, and where adjustment or other attendance may be necessary during the operation of the apparatus, insulating mats or platforms shall be provided so that the attendant cannot readily touch live parts unless standing on the mats or platforms.
