On a hand-held machine like a strimmer the earth wire is there to ensure that all the metal parts of the strimmer - that could be touched - are connected together and therefore are all at the same voltage, to avoid electric shocks.

Another Answer

Not sure why a 'two-stroke' trimmer motor would require an earth wire as it would not require an electricity supply.

Is the term earth ground the same as chassis ground?

Technically, only if the chassis is connected to true ground (earch ground). However, often chassis ground may be termed earth ground when the chassis ground iis the most common and final gound in the system...Type your answer here...Additional AnswerAn example of a 'chassis ground' is the way in which a vehicle is wired. One terminal of the battery (usually the negative) is connected to the vehicle's metal parts. One side of each electrical component is then connected to the metal parts, while the other side is connected, via a switch arrangement and a protective fuse to the positive terminal of the battery. The vehicle's metal parts then act as the return conductor back to the negative terminal of the battery, and we call this a 'chassis ground' or 'chassis earth'. The term 'chassis ground' is also applied to electronic devices where a metal 'chassis' containing the various electronic components provide the 'reference potential' for those components.By contrast, an 'earth ground' describes a direct connection to the general mass of the earth itself -often as a means of limiting a voltage rise, or as a means of providing a low-resistance path back to the supply in the event of an earth fault in order to operate a protective devices such as a fuse or circuit breaker. By common agreement, the general mass of earth is considered to be a zero-potential reference point.As the original answer points out, it is not unusual for a chassis ground to be connected to an earth ground.
