On mains wiring, you may have your phase connections wired directly to the busbars. You effectively have two methods of achieving this:
- Create a unique wire type called BUSBAR or more specifically the busbar size e.g. 20x6_CU. This will be reported in the wire from-to list
- Create a unique wire type called JUMPER. This will NOT be reported in the wire from-to list
In both methods, a terminal symbol may be used to represent the connection to the busbar. This can be given its own unique identifier so that it can be filtered out if necessary when producing the terminal strips but it can be useful to determine the amount of connections that are required (per phase or total) and help therefore in balancing the phases.
Instead of the connection dots, we can either:
a) use a terminal with wire number change if we want different wire numbers for the wires in comparison with the busbars
b) use a terminal with terminal number if we want the wire number to be continued throughout the connections.
We can change an existing wire type by right-clicking over a wire and selecting :
