MCC Manufacturers
MCC Manufacturers
(OP)
Hello,
Can someone tell me if there are any good MCC manufacturers or board builders in the USA or Mexico?
I was hoping for a board builder more than an ABB or Eaton or GE type.
Are there such companies that design and build a board to suit your requirements?

RE: MCC Manufacturers
I'll add Siemens and Schneider Electric to your MCC list.
RE: MCC Manufacturers
But I'm curious as to your use of the term with the term "build a board to suit your requirements". Here in NA, "MCC" meaning a Motor Control Center is a specific term for equipment meeting a narrowly defined specification and performance standard, listed to UL845 specifications. In general, NRTL panel shops are allowed to make minor modifications to control circuits only, they cannot modify or add power components to the MCC.* So building an MCC to suit your requirements is only possible within the confines of what is defined, tested and listed by the mfr in MCC format.
In other parts of the world, the term "MCC" is often more loosely applied to any cabinet into which motor controllers are installed. Here in NA, we call those "Control Panels" in order to differentiate them from MCCs. While many many people have built large control panels with multiple motor controllers all in one large box for decades, this concept has come under added scrutiny here because of recent emphasis put onto electrical safety procedures, especially with regard to arc flash protection of workers. A single cabinet design stuffed full of row upon row of motor controllers requires, in most cases, that the power be shut down before opening the doors for any reason, or for those opening the doors to be wearing appropriate PPE (Personal Protective Equipment), which if the system is large enough, means onerous suits, gloves and face shields. So if the equipment needs to continue operating if one controller is taken out of service, the older MCC conch where each controller has its own disconnect, lock-out mechanism and door has come back into favor.
