I have a utility transformer feeding a panel. The circuit feeding this panel should have 3 Hot & 1 Neutral. But Revit is adding a ground wire that I do not want. I have tried everything, including unchecking the ground check box, defined a 3 wire system, etc.
The reason why I need this information is I am providing the contractor with a wire schedule for circuits that have been upsized due to voltage drop. The ground wire is showing up in the schedule and I do not want the contractor to pull the wire Revit is forcing me to use.
I know this doesn't answer your question but aren't those conductors provided and installed by the utility? The contractor would only be concerned with the conduit.
Without filling up the discussion group with extraneous details of a specific job, I was trying to make the question as simple as possible. (Utility to CT, CT to Building)
So, how can you remove an unwanted ground wire?
I, too, would like to be able to remove the ground wire. With the latest Revit MEP 2012 Update, you can set the number of conductors to zero. However, this only seems to effect the tick marks for the wire annotation and doesn't in any way affect the circuits' properties. These "annotation" wires cannot be scheduled. I don't see a possibility of accomplishing this as of now...
Can you add a column and a check box under wiring types so that we can add and remove ground wires? Similar to Neutral wire.
Go down to the Wires families.
Right click and edit one of the existing families.
Do a saveas and name it whatever you want.
Delete the tick mark. Import it into your project.
Click on the Manage pulldown.
Click on wiring
Where is says ground wire tick mark and neutral wire tick mark, hit the pulldown on the right. your new family defined as with no tick mark should be in that list.
That is the correct method for removing the ground wire tick mark, but the ground wire still exists in the circuit. I have attached the schedule I am using and the properties of the circuit in question to help clarify what I am talking about. Thanks for the post, it is still valuable information if you are more concerned with the graphics of wiring.
