Labeling Electrical Panel

For Electrical Panels, the following Autotext parameters are available in the MEP category.

The Autotext parameters return the following values:

Panel Name - The name of the Electrical Panel. In case of circuits, the name of the parent Panel.
Load Phase A, Load Phase B, Load Phase C - The total apparent power load on the respective Phase (A, B or C). Calculation: The Apparent power of each Electrical Device is distributed equally among the Phases used by the circuit the device belongs to. Load Phase A, B, and C are the sums of all load portions assigned to Phase A, Phase B, and Phase C, respectively.

Example: An Electrical Device has an Apparent power of 15 VA, and it belongs to a circuit that uses only Phase A (circuits and their phases are defined in the settings dialog of an Electrical Panel element). The device’s full 15 VA load is added to Load Phase A. Another Electrical Device has an Apparent power of 40 VA and belongs to a circuit that uses both Phase A and Phase B. Its load is split equally between the two Phases (40 VA ÷ 2), so 20 VA is added to Load Phase A and 20 VA to Load Phase B. Load Phase A = 15 + 20 = 35 VA. Load Phase B = 20 VA. Load Phase C = 0 VA.

Note: If the Apparent power checkbox is unchecked for the device, or if the device is not assigned to any circuit (its Supply field is set to “Main”), it does not contribute to Load Phase A, B, or C.

Load Total - The sum of Load Phase A, Load Phase B, and Load Phase C.
Demand Load Phase A, Demand Load Phase B, Demand Load Phase C – The total demand load on the respective Phase (A, B or C). Calculation: The Apparent power each Electrical Device contributes to a Phase is multiplied by the Demand Factor of the device’s Load Classification. Demand Load Phase A, B, and C are the sums of all Demand Loads assigned to Phase A, Phase B, and Phase C, respectively.

Example: An Electrical Device contributes 15 VA to Load Phase A. Its Load Classification is set to “Lighting”, which has a Demand Factor of 0.8 (as specified in Electrical Project Settings). The device therefore adds 15 * 0.8 = 12 VA to Demand Load Phase A. Another Electrical Device contributes 20 VA each to Load Phase A and Load Phase B. Its Load Classification is set to “Sockets”, which has a Demand Factor of 0.5. It therefore adds 20 x 0.5 = 10 VA each to Demand Load Phase A and Demand Load Phase B.

Demand Load Phase A = 12 + 10 = 22 VA

Demand Load Phase B = 10 VA

Demand Load Phase C = 0 VA

Note: Devices that do not contribute to Load Phase A, B or C do not contribute to Demand Load Phase A, B or C either.

Demand Load Total - The sum of Demand Load Phase A, Demand Load Phase B and Demand Load Phase C.
