For decades, engineers had two unappealing options: either perform costly, time-consuming prototype tests in accredited laboratories, or apply extreme safety margins (over-engineering) that waste materials and space.
For professionals in electrical design and manufacturing, is a vital technical report providing a standardized method for verifying the temperature rise of low-voltage switchgear and controlgear assemblies through calculation rather than physical testing. iec tr 60890 pdf
