Copper Temp
Copper Temp
(OP)
Does anyone know what the maximum temperature is for copper bus??
We have some bus here that looks like it could achieve 200 degC during a short circuit. I am pretty sure the devices hanging off the bus are not good for more than 100 degc.
However, a co-worker said he remembers some bus off a transformer running at 300 degc? This seems extreme... ya think?

RE: Copper Temp
An oft-quoted ‘emergency’ temperature limit for insulated copper cables is 250°C in short-circuit calculations. I don’t know the origin of that figure—perhaps it is a judgment call where occasional excursion will not produce significant physical or electrical degradation. www.kerite.com/catalog/catalogfiles/short_circuit_limit...
