What is the technical term for the putty that electricians use to
seal
around service cables where they enter meter boxes, or pass through
walls?

For service cables, I use a weather head, bend the wires down prior to
entering the weather head (drip line), and don't use anything to seal
the holes.

For wires entering through the wall of a building, I route the wire
down, then back up (drip line), then use regular caulk.
