Don, this is very disturbing to me.

The use of common trip breakers or handle ties on the breakers feeding a multiwire branch circuit would make the OSHA required lockout of all of the hots on that circuit automatic.

So now we are saying IBEW trained (or otherwise trained) electricians need the protection to be automatic. [Linked Image]

This is truly a sad state of affairs if electricians can not be properly trained.

Lets just install shunt trips on all circuits, activated by micro switches in every box, that when you take the cover of the box it would trip all associated breakers.
