A chassis ground is a link between different metallic parts of a machine to ensure an electrical connection between them. Examples include electronic instruments and motor vehicles.

Usages

Electronics 
Most electronics systems have their circuits reference-linked to the chassis while the chassis itself is often, but not always, linked to the Earth.
Motor vehicles 
Most motor vehicles use the chassis as the reference for all electrical peripherals which allow to use only one wire for each accessory.

Confusion

The chassis must not be considered as a link to the Earth. Depending on the usage of electrical machines this may, or may not, be the case. For example, in all cars metallic parts are linked together they are not linked to the Earth
