Electrical Room Heat Load

Enter each cabinet type, its ampere or kVA rating and how many there are. RokBench estimates the heat each one gives off and the cooling or ventilation it takes to remove it.

Screening

Equipment in the room type, rating and quantity are enough — defaults fill the rest

Result

List the equipment in the room with its rating and quantity, then calculate.
