Temperature of the wiring terminals in the distribution box
According to UL 1059, every terminal block must carry a verified maximum operating temperature, typically ranging from 85°C to 150°C depending on the housing material and conductor size. In the daily maintenance of power distribution systems, the biggest concern is the unexplained overheating of the wiring terminals. In fact, the fact that the earth distribution block does not overheat during long-term operation at rated current directly determines the service life of the entire. When terminations are inside equipment such as panelboards, motor control centers, switchboards, enclosed circuit breakers, safety switches, etc. Manufacturers commonly use 90°C-rated lugs. In electrical installatio...
