Hello!
The green wire that comes out from the outlets of home appliances such as refrigerators, washing machines, and microwave ovens...
Do you know anything about this? 
The answer is "earth wire".
The ground wire is installed to dissipate excess electricity to the ground when a voltage higher than normal is applied, such as due to an electric leak or lightning strike.
If you connect this ground wire,
In the event of an emergency, electricity can be released to the ground.
Damage to the human body can be avoided.
By the way, you don't have to be a professional to connect the ground wire yourself.
<How to install the ground terminal>
▽For screw type
1. Open the ground terminal cover and loosen the screw with a Phillips screwdriver.2. Place the end of the ground wire between the screws.
3. Close the screw
4. Pull the ground wire to make sure it doesn't come off, close the cover, and you're done.
▽For one-touch type
Just insert the copper wire part at the end of the ground wire all the way into the socket!
-----------------------------
If you run out of ground terminals for multiple home appliances, there is no problem in connecting multiple ground wires to one ground terminal.
If you purchase an extension ground wire at a home center or EC site,
It is also possible to extend the length by tying the copper wires together.
*It is good to wrap the knot with insulating tape, etc.
Because it's something you use almost every day,
You want to use home appliances safely!
When you are busy with moving,
If you're living alone for the first time, you're already nervous, but you don't want to add to your anxiety and unknowns.
I would be happy if I could connect you with some peace of mind.
Well then, please look forward to the next blog.
