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
+ and - voltages not connected to earth
GROUND
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.
All chassis/frame grounds are connected to Earth ground.
Check the continuity of the ground wire from both the ends. Ensure the ground wire is properly connected to earth / ground terminals
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.
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
Yes, all receptacles require an earth ground. (the bare copper wire in house wiring). However, it is not a dedicated ground in that all ground wires in a houses electrical system are connected or in common.
