Problem in single phase panel board

[m7moud_alfat7]

Dear All,

I wish to find a solution for the problem in the below image as highlighted it's about the following

we have a project for hotel and we should provide the guest room single phase so I updated the family M_Lighting and Appliance Panelboard - 480V MCB - Surface  attached in the RME advanced sample project and set the no. of poles to be 1 also the apparent load phase 1 to be 277 volt as 1 phase voltage and when I connected the branch circuit on this panel it showed apparent load phase A and  apparent load phase B so please help me for this problem as soon as possible

I found this previous thread Single pole - single phase panel schedule

and after this long discussion and all these replies my only wish from aitodesk is to provide system for America and other countries because of the confusion

of definition such as the single phase definition also the system for wire size (AWG vs. mm2) in the upcoming version of revit

We've actually been working with Autodesk on wire sizing and circuit control. We also use a US product call Designmaster, which has a Revit plug in that sizes breakers and wires based on the load assigned to the fixtures, rather than the breaker load defining the wire size. Check it out here:

It's an excellent application that may help you out with your loads. For now, on projects where we are not using this tool, we manually enter wire sizes with a project parameter that's based on a shared parameter value, using common text values.

Hope this helps - thanks - David B.

Also, here's a link to a post I wrote early this year about how Revit handles loads assigned to a panel - hopefully it will help explain how this is supposed to work.

please help 😞 See screen cast. Cant change to single phase panel or connect my ac unit.

Hello,

According to your video, the load is 240V one pole load, which means that the voltage between L-G should be 240V.

None of the distribution systems you have in your project file corresponds to this setting.

If you look carefully, you will see that L-L voltage is 240V, if you want to use this distribution system, your load should be 240V and 2 pole load.
