Grounding Practices
Proper grounding is necessary for optimum performance, reliability, and safety. Improper grounding will result in uncontrolled electrical circuit paths and in unreliable electrical circuit paths.
Uncontrolled electrical circuit paths can cause electrical activity that is unsafe. Uncontrolled electrical circuit paths can also degrade the electronics and communications.
Ensure that all grounds are secure and free of corrosion.
