In North America, orange outlets are normally isolated ground outlets. The
color does not signify the voltage. Only the outlet pin configuration is
used to determine the voltage.
On most North American outlets, the ground connection on the outlet is
connected to the outlet mounting frame. When the outlet is installed, the
ground is automatically connected to the electrical box. If metal boxes
and conduits are used, this connects the ground through the conduit in
addition to the wired ground.
The ground screw on an orange outlet is not connected to the mounting
frame. If these outlets are installed in a metal box, the only ground
connection will be through a ground wire to the electrical distribution
panel. They are often used in applications where ground loops would be a
problem.

Greetings folks,
I seem to remember from my previous life in test labs, that orange colored
power outlets are exclusively for non-US power, specifically 230V AC. Just
did some reading on the National Electric Code online and cannot find this
rule anywhere.
What gives? Thanks
Anil
