Limitation in number of feeders for LV / MV Switchgear

[NickParker]

Is there is a limit to number of feeders in the LV / MV Switchgear?
I hear there could be upto 24 funtional units per cubicle. where is this put in the standards?

Per CUBICLE in MV? I seriously doubt that! In MV switchgear, there would be ONE feeder unit per cubicle, 2 per SECTION, depending on size.

For LV SWITCHGEAR it is similar, but SwitchBOARDS and PanelBOARDS, which are a different set of standards, can have multiple feeders per unit (structure). The limit has more to do with the temperature rise, so would depend greatly on the size and scope of the equipment.
