Busbar Drilling
Busbar Drilling
(OP)
Hello,
Can anyone give me information on the ampacity-rating effect of drilling holes (for conductor terminations) into copper busbar?
Thank you in advance!

RE: Busbar Drilling
The hole itself doesn`t have a significant effect on ampacity unless you are using very unusual designs.
Ampacity of a boltet joint depends on a lot of factors:
quality of surface
hardware used (size and material)
applied torque
acceptable temperature rise
If you are considering connecting a cable as a tap to a busbar the maximum temperature of the cables isolation may limit the ampacity of the busbar.
