I know that when obtaining voltage for metering from busbars that any existing holes must be marked "TAP" in order to utilize them for voltage taps. Moreover, since drilling a busbar voids UL listing, that would require UL re-certification. Many times there are no existing tap holes nor existing breaker or space for one to obtain metering voltage. I also know that usually a mechanical lug is supposed to be rated for more than one conductor to utilize it that way. I have normally seen utility providers and many others obtain metering voltage feed by sandwiching the conductors under service conductors in the mechanical lug. Is this permissable, or shouldn't it be, provided the smaller metering voltage wiring is securely connected and not subjected to damage by gross deformation like what would happen if the lug screw were run down on it?
