MCC Compartment Temperature Rise
(OP)
Can someone tell me how to go about working out the potntial temperature rise in a MCC compartment.
Any help would be appreiated.

RE: MCC Compartment Temperature Rise
UL may have some standards as well. They don't use 90 deg C wire in there for nothing.
RE: MCC Compartment Temperature Rise
There are also a number of resources for estimating the heat gain for electrical equipment: I use a book, "HVAC Equations, Data, and Rules of Thumb" by Arthur A. Bell, Jr. for estimating A/C needs for MCC rooms --

TRAA(degs F) = 4.375 degs. F / sq.ft. (1)
So if you have a 48" X 36" X 16" enclosure that has 300 watts being dissipated within it, this would mean that:
2[(48x36)+(48x16)+36x16)] / 144 = 42 sq.ft. (2)
300 watts/42 sq.ft. =~ 7.1 watts/sq.ft. (3)
from (1) we get: 7.1 X 4.375 =~ 31 degs. F. rise
Hope this helps.
