    Default Number of wires

    I’d like to change the number of wires under Electrical Settings > Distribution systems > Wires. Current options are 1,3 and 4 wires and I need to use a 5 wires type. Does anybody have an idea?

    Thanks,

    Frank

    Is it a five wire system (multi-phase HV transmission?) or just a one/three phase with multiple connections?

    To do this you can add two electrical connectors to the same family with the associated electrical data on them. (ie. one 3P/3W connector and one 1P, 2W connector = 5W and 3 or 4P) This is kind of bulky with the "connect to panel" button, but it gets the job done (eventually).

    You can add as many electrical connectors as you want, it just gets kind of annoying keeping track of all of them. (name the connectors!)

    The reason why I need 5 wires is beacuse 3 wires are the 3 phases, 1 wire is grounding 1 wire is 0. This is the most common wire type in Central Europe so it would be very useful to have it as an option

    I believe that is implied for a 3 phase feeder in Revit. As far as the connection is concerned it is only three wires, but when you actually look at the home runs. (Look at the home run wire properties) you will see a count of all the hot, neutral and ground wires on that run of wire. If you turn on tick marks for that wire it will put them in as needed.
