When installing an electrical outlet, many individuals don't know which way is up.
Technically, it doesn't matter whether you install the outlet with the ground hole up or down, according to electricians.
The NEC enables ground plug holes to face up, down, or sideways.
No standard outlet orientation exists. That implies there are no upside-down outlets.
If the outlet is connected properly, neither is safer.
It's all about aesthetics, so do what you want. The United States instals the ground plug upside down, whereas Canada does the reverse.
