Dedicated Outlet and Isolated Ground

In an office I have a laser printer that requires a dedicated outlet. The oulets we have available to use have a small triangle at the bottom. The triangle isn't orange but black and the outlet faceplate is tan and the receptacle is tan too. I'm assuming the black triangle means it's an isolated ground. Is an isolated ground always a dedicated outlet? And is a dedicated outlet always an isolated ground? If it's not already a dedicated outlet is it expensive to make it one?

In other similar offices I've noticed orange receptacles with orange (maybe green) triangles at the bottom. Are these both isolated grounds and dedicated outlets or just one or the other?

Any help is greatly appreciated?

Typically a receptacle with the triangle you describe is a isolated ground , but the fact that some are tan while others are orange raises other ?'s. Is there a back-up generator or emergency power source in this building? If so then that may explain the color difference i.e. orange for emergency power tan for iso ground. but that is a guess. To answer your second ? if it is a isolated ground then it is a dedicated circuit which does not necessarily mean it does not serve other iso ground recepts in other offices. more info may be needed to answer these ?'s with any certainty.

 

Thank you.

There's no generator or back up power.

So an isolated ground is a dedicated outlet, but it could have other outlets in the circuit. Is that right?

Yes it is dedicated in the fact that it was meant to serve specific equipment. But not that it only serves that one receptacle. (unless that was what was spec by the engineer when the building was built)

 

Isolated grounds are not necessarily dedicated outlets. Most of them in our office are not dedicated. Dedicated outlets are necessarily to be isolated ground.
Isolated and dedicated are 2 different things. Receptacles can be either or both.

 

Thank you both.

Is there a symbol for a dedicated outlet that I can look for either on the plans or on the receptacle?
