How Ground Fault Circuit Interrupters Work & Protect Us from Shock: Electrical Ground Rules Whitepaper

How do ground fault circuit interrupters work?

This Electrical Ground Rules white 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. In this part, we will examine our use of ground as a means of protection from ground faults, and how ground fault circuit interrupter (GFCI) devices operate to protect us from severe shock. We also answer these questions:

  1. What does a How Ground Fault Circuit Interrupters Work & Protect Us from Shock: Electrical Ground Rules Whitepaperwired earth ground really protect you from?
  2. Does it protect you from electrocution?
  3. 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.
