'...What criteria should be considered when deciding whether the panel should be classified as an LV switchgear, LV distribution panel, or MCC?'
I have the following opinion for your consideration.
1. In the IEC world, these LV boards are covered by the IEC 61439-...,which are rated <1 kV ac or 1.5 kV dc.
2. For LV gears , e.g. ACB, MCB, MCCB, contactors etc., are also based on <1 kV ac or 1.5 kV dc.
