WHITEPAPER: Electrical Ground Rules Part 2
Best Practices for Grounding Your Electrical Equipment
This Electrical Ground Rules paper is Part 2 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. Part 2 examines electrical ground rules in more depth, and includes answers these questions:
- What does a wired earth ground really protect you from?
- Does it protect you from electrocution?
- What if your appliance does not include a connection to earth ground and you become the path of least resistance for some sort of ground fault?
We begin with a discussion on the use of ground as a means of protection from ground faults. Additionally, we cover how ground fault circuit interrupter (GFCI) devices operate to protect us from severe shock.
- 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:
- stabilizing electrical signals
- limiting transient voltages and current
- Electrical Ground Rules, Part 3: Best Practices for Grounding Your Electrical Equipment:
- reviews ground and its role as a voltage stabilizer and transient limiter
- offers tips on what you can do to improve your connection to ground to realize benefits to safety and signal integrity
