I tend to be careful. First, understand what's going on if you can. Then check that the hots that you think are controlled by the breaker really are. Compared to a professional electrician I work slow. But I've done a lot of work and I'm still here.
Never seen inside a bus duct. (I've done next to no commercial work.) Was the problem that the busbar alloy was corroding?

The aluminum in the alloy was breaking down and causing performance load degeneration over time.No structural failure just a flawed value engineering and not knowing the time element of material demise(ALUM)Naturally the addition of electric plus salt intrusion amplified demise.No more metal now in exposed(wet)areas (pools)All Seal Tite,PVC conduit,J boxes,Plastic splash guards on all plug in devices.All GFI at wet areas(Public areas a must).
