Motor Work Areas

Dec. 3, 2019
Watch out for these hazards when replacing a motor

Replacing a motor presents special hazards. Here are some to be aware of:

  • Trash or product on the floor. The working space area, as defined by Art. 110 of the National Electrical Code (NEC), must be clear of any kind of clutter.
  • Grease on the floor. If the motor has been over greased or the last person who lubed it didn't clean up properly, there may be grease on the floor. The associated couplings and the driven equipment may drop grease on the floor. Look carefully.
  • Oil on the floor. The associated gearbox might be leaking; if you smell the distinctive odor of gear oil as you approach the motor, check carefully for oil.
  • Sharp edges. Motors usually don't leave the factory with sharp edges. But what happens between then and when you go to lower the motor in place can produce them. Upon arrival at your facility, the motor should be inspected for several things and sharp edges is one of them. Inspect for sharp edges before trying to move it into its final position, too.
