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 AnswerNot sure why a 'two-stroke' trimmer motor would require an earth wire as it would not require an electricity supply.
If you connected neutral and earth (ground) to each lead in an LED and it glowed then this would be evidence of a ground fault.
All chassis/frame grounds are connected to Earth ground.
An earthing system is a system where circuits are connected by a ground. An insulated return system is how power is transferred to trains.
A: GND is short for ground. There are many grounds earth ,signal ,power etc. It means a zero potential as a reference to what ever else is connected to
Because everything always has to be grounded, for safety. If a 'ground' is not available, as in an aircraft, all the external containers for the different items of equipment are all connected together to the local 'earth'.
Grounding?AnswerIf a line conductor is unintentionally connected to earth, then it is an earth fault.
Measure the ground resistance from the user end point, where earth or ground cable is connected. It will show a very high resistance or open if ground is broken.
If you connected neutral and earth (ground) to each lead in an LED and it glowed then this would be evidence of a ground fault.
Check the continuity of the ground wire from both the ends. Ensure the ground wire is properly connected to earth / ground terminals
All chassis/frame grounds are connected to Earth ground.
A conductor that is directly connected to the earth is called ground. One of its applications is through the determination of the field strength of surface wave radio transmissions.
if ground isn't connected and the applience is conductive the applience could shock you if live and earth are the wrong way around and you touch the ground or something connected to it you will be shocked.
One -- it is all connected above ground and extends miles into space.
The ground wire should be connected to the grounding terminal or bus bar in the electrical circuit to provide a path for excess electrical current to safely flow to the earth.
No. An earth wire (commonly called a ground wire) has no current flowing through it. It is simply a wire connected to the ground to discharge electrical current in a circuit.
EarthIts a earth groundat lower potential then your service
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.
