How could an improper electrical earthing connection affect an appliance?
Wiki User
∙ 12y ago
In a properly operating appliance, there is no connection between any of its internal wiring and its chassis and/or its metal case, if there is one. As such, the earthing connection being improper will not affect the operation of the appliance.
However, and this is critical, an improper earthing connection can present an electrocution hazard to the user...
If the earth connection were electrically live or "hot", for instance, then the chassis of the appliance would also become live or "hot". Touching it, along with a real earth connection such as a water faucet, could cause electrocution.
Additionally, if the earth connection is simply missing, then an internal malfunction within the appliance could cause the chassis and/or its metal case, if there is one, to become live or "hot", creating the same risk of electrocution.
The purpose of the earthing connection is - in the event of appliance malfunction - to cause a high enough fault current that will force the protective device (fuse or circuit breaker) to trip and break the supply of current to the appliance.

Indicate the ways that an electrical fire could start in your workplace?
Overloaded circuit Defective product Damaged cords Overloaded appliance Unsafe use of ladders near overhead wires Improper maintenance of high-voltage devices
Why is grounding important?
Every electrical system should be earthed to get a low resistance path for dissipation of current into the earth. Major accidents take place because of improper equipment earthing or leakage current. Earth fault current directly affect the human safety. Earthing should be measured at regular intervals so as to ensure that the resistance of the earth is maintained minimum. Its main purpose is to minimize the risks of fire and shock hazards.
