Why Chassis Ground Is Important?

Chassis grounding is an important part of the ground separation strategy to reduce ground noise. It provides a dedicated return path for the ground current to earth ground. Chassis grounding not only helps in protecting the PCB from surges and ground noise, but it may also act as a shield against EMI.

What is the purpose of a chassis ground?

Chassis grounding serves the same purpose for electronics as lightning protection does for high voltage power systems. Specifically, to route unwanted and potentially dangerous current away from the system elements and components to prevent circuit operation interruption and damage.

Why is ground so important?

One of the most important reasons for grounding electrical currents is that it protects your appliances, your home and everyone in it from surges in electricity. If lightning was to strike or the power was to surge at your place for whatever reason, this produces dangerously high voltages of electricity in your system.
