How it works

A grounding system connects the electrical system to the ground through a thick conductor wire. This provides a separate pathway for current to flow back to the ground in the event of a short, lightning strike, or electrical surge. 

Benefits

Grounding is a requirement of many electrical codes and regulations. It also stabilizes and optimizes system performance. 

How it's done

An electrician connects ground and neutral wires to the main electrical panel, then runs copper grounding wires to each outlet, switch, and fixture. 

Types of grounding systems

There are three types of grounding systems: TN-S (separate), TN-C (combined), and TN-C-S (combined-separate). TN-S is the safest, while TN-C is less common and more susceptible to touch voltages. TN-C-S is a balance between safety and cost-effectiveness.
