Unable to connect electrical wires with wire bridge.
I have tested this with three variation of item placement.
I even tested it after connection the segment to the grid and an oxygen generator. (I removed one tile of wire from the middle section as it completed the circuit.
1 a) Place electrical wire along a length of wall with a one block gap in the middle. 1 b) Place wire bridge on gap. 2 a) Place electrical wire along a length of wall with no gap. 2 b) Place wire bridge in the middle. 3 a) Place wire bridge on the wall. 3 b) Place electrical wire on either side on the wire bridge.
