Panel schedule Connected and estimated current are totally wrong

[HVAC-Novice]

I use R2026.1 and have this 208V/3 panel schedule and everything looks correct. Except the highlighted " Connected Current" and " Estimated Demand Current". and it is extremely wrong. First row should be 25A, but shows 8A (even if i divide by 1.73 it still doesn't' make sense)

I saw some threads about some of those things being wrong in old versions. Maybe I just don't understand what the values mean? 

In the template editor They seem to be what they say they are:

These are my load calculation settings, and both options yield the same result. 

Somewhere i read it may be related to power factors not being 1. But what really is weird, the first few columns (up to " Estimated demand (VA)" seem correct. and i thought the current will be calculated from that?  

is this a Revit issue, or am i just not understanding what those two values are?

The value for total demand current is averaged across all three phases. You have 25 amps of clothes dryer load on phase B but 0 amps on phase A and C so the average amps per phase is 8.33. It's also 3000VA/208V/sqrt3.

Also, clothes dryers will normally be a 2-pole 30 amp circuit and the the NEC has a minimum of 5000 watts each for load calculations. 12.5 amps at 120 volts won't do much drying.

OK, i think i get it now. Looks like user error 🙂
