What happens if ground wire is disconnected?

What happens if ground wire is disconnected?

One problem with this arrangement is that if the ground wire is broken or disconnected, it will not be detectable from the operation of the appliance since the ground wire is not a part of the circuit for electric current flow. The ground wire of an appliance is the main protection against shock hazard.

How do you reattach a ground wire?

Second option: Reattach the wire If the wire crimps on or screws on, that may be fairly easy. Spread the crimp connection, slide the wire back in, and mash the connector back down. Or wrap it around the screw and tighten the screw.

What happens if something isn’t grounded?

The idea of the ground is to trip the breaker preventing damage to the device or electrical shock to the user. If the device is not properly grounded, and any of a number of events occurs, the device may be damaged beyond economical repair.
