I need to change the number of wires under Electrical Settings > Distribution systems. Current options are 3 or 4 wires for three-phase. Revit cannot create a 5-wire distribution system, the fifth wire representing a dedicated neutral wire. I need 5 wires where 3 wires are the phases, 1 wire is grounding and 1 wire is neutral.
Term "ground" is not quite clear. There are more options: - protective grounding conductor - functional earthing/grounding conductor - protective earthing/grounding and functional earthing/grounding conductor conductor - protective earthing/grounding and functional bonding conductor ... (see IEC 60050-195)
I have chcecked the terminology according to the IEC 60050-195. I need to create 5-wire distribution system in Revit > solidly grounded neutral system - TN-S - where S is defined by “Separated” which means that the neutral and PE conductors are separated > three phases (L1, L2, L3), protective conductor (PE) - term by IEC 60050-195 and neutral conductor (N).
@pavel.homan - what would adding an option for '5 wires' enable you to do? Presently, if you circuit a 3-phase piece of equipment, you, in fact, do have 5 wires as you described.. 3 phase, one neutral, and one ground.
Closing this as implemented, as the desired outcome of "I need 5 wires where 3 wires are the phases, 1 wire is grounding and 1 wire is neutral." is possible in the software already. Please feel free to add additional information or clarification if there are other previously unmentioned requirements or goals.
I hate to resurrect an old thread. I've come across this problem when searching for a way to implement dual neutral distribution systems. Some of my clients require 200% neutral bars for their panels hence 2 neutral wires are needed. So if I count the ground wire, I'd end up with 6 wires in total.
Unless I modify my panel schedules to make the 'Wires' field manually set, I don't see a way to have this information readily available within the model.
