What does grounding a microwave mean?

When you ground an appliance, you’re are making it possible for electric charge to equilibrate between that appliance and the earth. … That’s a nice safety feature because it means that you won’t get a shock when you touch the appliance, even if one of its power wires comes loose and touches the case.

Do microwaves need to be grounded?

For personal safety, this appliance must be properly grounded. The power cord of this appliance is equipped with a three-prong (grounding) plug which mates with a standard three-prong (grounding) wall receptacle to minimize the possibility of electric shock hazard from this appliance.

How do you ground a microwave?

Is a ground wire necessary?

In most electrical systems you will find a hot wire, a neutral wire, and a ground wire. The ground wire is not strictly necessary for the operation of a device, but it is still an important feature. This wire is designed to provide a path for electrical current to travel if the normal paths aren’t available.

Are ovens grounded?

Any kitchen appliance with a metal exterior needs to be grounded as a common-sense safety feature. It’s probably also required legally, wherever you happen to live. The magnetron requires a voltage of around 6 kV to operate. You don’t want any chance of that voltage getting out.
