Difference between switchgear and MCC
Difference between switchgear and MCC
(OP)
Wanted to find out the difference between switchgear and MCC. Drawing uses the term switchgear, but in manuals the same switchgear is referred to as a MCC. Is that just because it is switchgear that contains motor control circuits? Thanks!





RE: Difference between switchgear and MCC
"MCC" stands for Motor Control Center and is generally a manufactured assembly of motor starters and feeder breakers in a standard configuration and construction, per NEMA standards.
RE: Difference between switchgear and MCC
Once you get into Medium Voltage the differences tend to blur. Then again, the definition of Switchgear gets more complicated as well, i.e. Metal Clad or Metal Enclosed, Load Interrupter or Arc-Proof etc. In MV systems, especially Metal clad, motor control is often mixed in with "Switchgear" because it is often too expensive to have separate systems and the number of MV motor controllers is usually relatively small.

BTW, just to correct myself, the LV UL MCC classification is UL845, not 485.
