Bus Duct

Overhead bus ducts are often overlooked or neglected when performing electrical maintenance. Location and accessibility can make efficient bus duct maintenance a rather difficult task.

Infrared testing proves to be an efficient and effective method of catching potential trouble spots in bus work. Overheating at bus joints can easily be identified and problems with individual bus switches can also be pinpointed.
