I can't find it on their web site now, but you might aASHRAE has table for heat gain of electrical equipment, I believe. A Google search on the topic also turns up a few hits. Rafiq Bulsara http://wwWell, I calculated such a case a few years ago, it was more estimation than calculation. I found some Schneider Electric data referring to their BCSorry, once more. The enclosed Excel sheet is Ok, apart from a bloomer that at the "D" column should have the title "Heat (for poles)".Thank you all. Good data crisleon! Very helpful and your results are exactly what I am finding from my factory rep sources.What total result have you obtained after your re-calculating?
