I have the wiring diagram for the old panel i have a question on the reasoning behind running two wires to a an empty spot with no conductive matrial and the reasoning behind that
The orignal busbar has 7 slots 2 for hot 3 for negative and 2 that are open with bar plastic the wiring diagram on the inside shows a red wire and one end of the tilt tram fuse hooked ob to the first bar plastic slot and a round wire and a white wire also for the tilt and tram hooked on the last slot that is also bare plastic. Red I associate with hot and black with ground and white a common wonder if i need a sepreate busbar for those four wires
