Feedthrough Insulators
Hole In The Wall Tavern
<&feedthrough>Wires on their own cannot coexist with rock, or wood, or more industrial materials blocking their path.
With the careful application of terracotta insulation, a solid conduit can be constructed inside of these materials to conduct power.
The Feedthrough Insulator allows two connectors to be merged across one meter walls, and cannot connect more than one wire per connector.
They can be created with any "normal" solid block in the middle, by right-clicking either of two connectors with an Engineer's Hammer.
Non-structural connectors can be used to create feedthrough insulators for the corresponding wire type.
