Panelboard schedule shows correct total load, but "0" for many individual ckts..

[Anonymous]

The circuits are properly wired. Note that the loads for the individual loads shown add up to 3200, but the bottom shows the proper total connected load of 9460. There's clearly a pattern that develops (show two loads properly, then 4 at 0VA, repeat).  This is on Revit 2015.  Any ideas? Thanks.

I assume this is a custom panel schedule that someone has set up?  It's hard to tell just by looking at the schedule, but I would check single phase vs. 3 phase and make sure everything matches.  I would also check balanced vs. unbalanced loads.  And I would also edit the panel schedule and make sure you have the correct parameters in the load column.

If that doesn't help, maybe you coudl post a revit file that includes the schedule.

I assume this is a single phase panel.  Are the loads all standard receptacle families?  Are they a different family than the ones correctly showing loads?  My first guess based on the information I have is that there's a power factor assigned to the null loads.  Check the connector in the family (assuming that the null loads are all one family and the working ones are another).

Thanks for the advice.

Stever, tried that with no luck.

Bsammis, they are different families of receptacles, but there is no consistency to the errors. Circuit 1 full of Family A will be fine and Circuit 2 full of Family A will show 0.

For future reference, it turns out that disconnecting and reconnecting each "faulty" circuit fixes the problem. Had a bunch to fix so it took a while, but it works.

Huh. Stupid Gremlins. I've only actually experienced that in the opposite direction - the panel schedule will be perfect, but the panel/circuit info from the connector isn't pushed out to the family for tagging/equipment scheduling purposes, and only with some mechanical equipment.

Yes, gremlins.   I think things are better now, but I remember not too long ago when panel schedules would take forever to update.

Change a circuit name, and can't figure out why it didn't show up on the schedule.  Check again.  Save and reload.  close the view and reopen it.

Sometimes I had to delete the schedule off the sheet and reinsert it just to get a minor change to show up.
