The Term "Switchgear"
The Term "Switchgear"
(OP)
Why is it that a Switchgear is called as Switchgear? Literally, is there a "mechanical gear" on the equipment?
When was the last time you drove down the highway without seeing a commercial truck hauling goods?

Not to add too much fire to the flame, but what is the significant difference between metalclad switchgear and metal-enclosed switchgear?
How did it the difference in terms evolve?

metal enclosed = load interrupter fusible switch gear
How they evolved, I do not know. Maybe someone selected one of the two names and then had a hard time thinking of something to call the other.

Metal Enclosed: (as opposed to what, wood?) there is only one switching device in each structure section. There is no removable cell, so if maintenance or repairs need to be done to a unit, the entire line-up must be shut down because of the risk to exposed common bus bars. This means they are not really suitable for critical equipment that must be kept running while other units are being serviced. Faults are still isolated, but damaged units mean shutting down the entire line-up to replace or repair them. With only one device per section, a lot of switching devices takes up a lot of linear (wall) space. Initial capital costs are however lower.
There are twists and exceptions to these generalities and new designs seem to be blurring the lines but that is the gist of it.
