To feed through power, signal, and data is the classical
requirement in electrical engineering and panel building.
The insulating material, the connection system and the
design of the terminal blocks are the differentiating fea-
tures. A feed-through terminal block is suitable for joining
and/or connecting one or more conductors. They could
have one or more connection levels that are on the same
potential or insulated against one another.
