Permissible operating temperature of busbar joints
The IEC 61439-1 sets the thermal limit in busbars working at the maximum working load. Here, 140°C (which is 105K over the ambient temperature of 35°C) is the upper safe temperature limit. With the aid of a correction factor (k2), the continuous currents specified in the follow-ing table may be adjusted to alternative oper-ating temperatures. A maximum temperature-rise of 55 K for bare (uncoated) Aluminium busbars and conductors (Al-Al joint) shall not exceed, to ensure safety & performance of the solution over a prolonged duration of service. Also attaching excerpts of IEC 61439 Ed.
