MCC/Control panels in water/wastewater treatment plants.

[Mefi01]

Hello everyone,
From water electrical engineers point of view, what does ‘Production of MCC/ Control Panel details including ICA information’ mean? Also, could anyone share any useful materials or guides on the design of control panel and MCC in the water industry .

Thank you.

Any replies please

Without a relevant location, context and a definition of "ICA" it's almost impossible to decipher what you are asking for.

I would have to conclude that you're quoting a bit from a "scope of work" document or description. This would indicate that producing block diagrams, construction specifications, and perhaps detail drawings of certain HMIs, standardized sensor or flow control assemblies, etc. are included in the required tasks. The major manufacturers of MCCs, as well as custom panel builder's shops have people on staff that do this. Recognition of a clients specific existing standards, protocols, and equipment is often where people doing these tasks struggle.

Me wrong? I'm just fine-tuning my sarcasm!

Great thank you all, any more answers please

Still don't know where you are, and that makes a difference.

In you are in North America, there are NEMA standards for the design and construction of MCCs and in the US, there is UL-845 as the testing authority spec and in Canada it is CSA C22.2 No. 254-05. Control panels in NA typically must be constructed per standards that allow for listing by a "Nationally Recognized Testing Lab" (NRTL), the most well known being UL, and they have a design standard called UL-508A and CSA CSA C22.2 No. 14, both of which are reciprocal. All of those standards dictate the minimum design and performance requirements.

Outside of North America, MCCs are not built by manufacturers so much as they are in NA, they are more often built one-off by independent assembly shops / system integrators, using pre-formatted "systems" from the component manufacturers. Likewise with control panels. I'm not familiar enough with IEC or BS standards to know what they may require, but others here are.
