WHITEPAPER: Electrical Ground Rules Part 3

Best Practices for Grounding Your Electrical Equipment

This Electrical Ground Rules paper is Part 3 of a three-part series that takes a look at grounding and its role in protecting personnel and equipment, and ensuring the integrity of electrical signals. Consideration of ground can be very complex and application specific. But in many of these applications, when we make wired connections to ground and to electrical equipment, there are a few rules of thumb that are helpful. Electrical Ground Rules Part 3 examines ground and its role as a voltage stabilizer and transient limiter, as well as offering tips on what you can do to improve your connection to ground to realize benefits to safety and signal integrity.

In this part, we will examine:

  • Ground and its Role as a Voltage Stabilizer
  • Ground as a Transient Limiter
  • Improving Your Connection to Ground
  • Basic Ground Rules for Wired Equipment

Also see:

  1. Electrical Ground Rules, Part 1: Best Practices for Grounding Your Electrical Equipment:
    • addresses the concept of grounding, the AC power system and its use of ground
    • gives three main reasons why we ground electrical equipment:
      1. safety
      2. stabilizing electrical signals
      3. limiting transient voltages and current
  2. Electrical Ground Rules, Part 2: Best Practices for Grounding Your Electrical Equipment:
    • reviews the use of ground as a means of protection from ground faults
    • also looks at how ground fault circuit interrupter (GFCI) devices operate to protect us from severe shock
