ABSTRACT RP-1395 is a continuation of an earlier project where the heat dissipated by indoor power distribution equipment is estimated. In RP-1104 certain equipment were examined while others were not. The goals of RP-1395 was to provide verification of some of the information presented in RP-1104 and to investigate other types of equipment not previously covered. The scope of RP-1395 is presented and the project results are summarized. Certain RP-1395 equipment items are not presented here because these devices have been adequately treated in recent publications. The equipment items not covered in this paper are medium and low-voltage switchgear and adjustable speed drives.
