Electricians working on commercial projects may follow engineering specifications that call for this orientation throughout the building.
The reasons include:
- Improved safety.
- Consistent installation practices.
- Easier identification of certain circuits.
- Compliance with project specifications.
If you’ve ever worked in an office building and noticed upside-down outlets, there’s a good chance they were installed intentionally rather than by accident.
Is It Required by Electrical Code?
Here’s where many people get confused.
Contrary to popular belief, there is generally no universal electrical code that requires
all outlets to be installed either ground-up or ground-down.
In many places, both orientations are acceptable as long as the outlet is installed properly and meets all applicable electrical requirements.
That means an electrician can legally install an outlet with the grounding hole on top, on the bottom, or even sideways if the installation allows for it.
