Panelboard Total Load on Phase B is not adding up correctly

Anonymous — Wed, 06 May 2020 18:54:57 GMT

I am using J-boxes to make Existing loads for a panel schedule, Phase A and C are fine and total correctly but Phase B has 2 J-boxes both with 1680VA and a Lighting circuit with a load of 2132VA this circuit has 2x4s, downlights, etc.. the total load should be 5492VA but the load is in at 5430VA and I can't figure out the issue. I deleted the J boxes and the total was 2132VA like it should be so it seems the issue is with the J boxes but neither of the other phases is having this issue and they are comprised on only J box loads.

Hello,

Did you check if the power factor of all loads are set to 1? The default sum method for the power is a vector sum.

Under the Manage tab I went to MEP Settings > Electrical Settings. I changed my Load Calculations settings to Sum apparent load. Everything is adding up straight forward
