Parameters
The calculated values on this data sheet are based on the following parameters:
Ambient temperature ºC |
35 |
Busbar temperature ºC |
65 |
Temperature rise ºC |
30 |
Supply Frequency Hz |
60 |
Emissivity |
0,4 |
n= number of bars in parallel
Current ratings assume still but unconfined air, with busbar mounted on edge.
Current ratings are based on “Temperature Rise of Busbar”, H.B.Dwight; Gen. Elec. Rev., vol 43.
For multiple bar arrangements, the space between bars is equal to busbar thickness.
AC ratings are based on spacings at which the proximity effect is negligible.
These approximate calculated values should not be regarded as a subsitute for experimental testing
