PROPER GROUNDING OF ELECTRICAL EQUIPMENT
PROPER GROUNDING OF ELECTRICAL EQUIPMENT
(OP)
I am building a pressure system made up of 2 blowers mounted onto a metal skid assembly.
What is the proper method to gound the blowers onto the skid using a standard ground lug ? I am asking what sequence of components (washer, star washer, ground lug, lock washer, etc..) should I use when installing the grounding lug ?
Should it be something like this (starting at the base metal):
-base metal
-washer
-ground lug
-lock washer
-nut
Also - I am told that paint and hot dip galv. must be removed from under the grounding lug - any special considerations in doing this ?
Thanks for any input

RE: PROPER GROUNDING OF ELECTRICAL EQUIPMENT
-Base metal (cleaned with scotchbright type pad and no-ox-id electrical grease applied)
-Ground Lug
-Flat Washer
-Lock Washer
-Nut
A lock washer shouldn't be allowed to dig into the lugs faces.
