Tapping a Discontinued Switchboard

[xptpcrewx]

I run into this quite a bit and rarely
Support a game plan for tapping the bus in any circumstance. Question for those in The field . How common is it to have the bus bars provided with the factory templates where is ok to drill/tap . I’ve heard it mentioned a lot and if that were the case it would be much easier to get On board but just curious how common it is to have those

Based on my experience not common. Maybe someone else has a different perspective?

There is often not a whole lot of thought given to what someone might need to do down the road. Or sometimes those things put in for future contingency have been used.

I try not to design myself into a corner because it might be me that needs to add one circuit breaker down the road and it's nice to have some place to to do that without having to go to extreme measures. But, it's also not that unusual to have space for an extra circuit breaker for instance, and end up using it because somebody decides to add something before it even leaves the shop.
