Heat Loss for Electrical Equipment
Heat Loss for Electrical Equipment
(OP)
Looking for published data or "standard" (such as ANSI, ASHRAE, or other reliable source) in tabular form, if possible, of heat loss in electrical equipment, such as starters, busduct, low and medium voltage breakers, power circut breakers, etc. I presently have some unpublished data, and do not know where it came from. I am using this data in a spreadsheet to calculate the total heat gain into electric rooms, and provide this information to the HVAC designers for sizing the unit for these rooms. Any helpful web links would be appreciated. And Thanks in advance.

If you come up with anything to the contrary, please let me know.
Transformers and other energy conversion equipment are obviously a different story. Transformers are typically 97 to 99% efficient, the remaining 1 to 3% is rejected as heat.
