Ein Schalttafelplan dokumentiert jeden Stromkreis in einer Verteilerleiste.
NEC 220.11 erfordert die Berechnung der Last auf jedem Stromkreis.
| Panel | Circuit | Load Type | Watts | Voltage | Demand Factor | Demand VA | Demand A |
|---|---|---|---|---|---|---|---|
| MDB-01 | C01 | Lighting | 2,400 W | 230 V | 1.00 | 2,400 VA | 10.4 A |
| MDB-01 | C02 | Socket Outlet | 3,600 W | 230 V | 0.80 | 2,880 VA | 12.5 A |
| MDB-01 | C03 | HVAC | 12,000 W | 400 V 3φ | 1.00 | 15,000 VA | 21.7 A |
FrameAI summiert jede Schalttafel zu einer Zuleitungsbelastung.
| Panel | Lighting VA | Receptacle VA | Motor VA | Fixed VA | Total Demand VA | Feeder Amps |
|---|---|---|---|---|---|---|
| MDB-01 | 2,400 | 6,880 | 9,000 | 7,200 | 25,480 VA | 36.8 A |
Schalttafelplan-Ausgabe enthält: Panelname, Stromkreis-ID, Lasttyp, Watt, Spannung.
