Panel Properties

This tool opens the Properties palette for the panel assigned to a circuit. This tool is not available when you edit a circuit to which no panel has been assigned.

Viewing panel properties

1. Select a panel in an existing circuit.
2. Click Modify | Electrical Equipment tabProperties panel Properties.

   The Properties palette displays the following instance parameters for the panel:

   Parameter	Description
   Electrical Engineering
   Schedule Header Notes	Specify static text to add to the Panel Schedule header.
   Schedule Footer Notes	Specify static text to add to the Panel Schedule footer.
   Electrical Loads
   Total Connected	The sum of the loads connected to the panel
   Total Estimated Demand	The total estimated load demand.
   Total Demand Factor	The total demand factor.
   Total Connected	The sum of the Power loads connected to the panel
   Total Estimated Demand (Amps)	The portion of the total Other load, adjusted for demand factor, connected to this panel. See the example for HVAC Total Estimated Demand. See Demand Factors.
   Apparent Load Phase A	The real and reactive power used by Phase A. (Phase A Apparent Current x Voltage)
   Apparent Load Phase B	The real and reactive power used by Phase B. (Phase B Apparent Current x Voltage)
   Apparent Load Phase C	The real and reactive power used by Phase C. (Phase C Apparent Current x Voltage)
   General
   Panel Name	Name assigned to the panel
   Mounting	Surface or Recessed
   Enclosure	Type of panel enclosure - Type 1 or Type 2
   Electrical Circuiting
   Max #1 Pole Breakers	The number of single pole breakers for the panel
   Mains	The rating for the mains feeding the panel
   Circuit Naming	Determines the format for the Circuit Number parameter that appears for circuit properties and identifies the circuit in the System Browser. Prefix types: Panel Name - uses the panel name as the prefix for the Circuit Number. Prefixed - uses the string entered for Circuit Prefix as the prefix for the Circuit Number. Standard - no prefix is used with the circuit number in the Circuit Properties. Only the circuit number is displayed.
   Circuit Prefix Separator	The character or string that separates the prefix from the circuit number.
   Circuit Prefix	The text string used as the prefix when Prefixed is selected for Circuit Naming.
   Modifications	Can be used to note features or changes that will appear under the Modifications section of the panel schedule.
   Short Circuit Rating	Short circuit rating defined by the manufacturer.
   HVAC Estimated Demand	The portion of the total HVAC load, adjusted for demand factor, connected to this panel. For example, assume that HVAC demand factors are specified as 100% for 0 VA - 100 VA and 50% for greater than 100 VA. Further, assume a total HVAC load for the project of 600 VA. When the HVAC demand factor is applied, the total estimated demand is (100 VA x 100%) + (500 VA x 50%) = 350 VA. Now consider three panels, P1 with a total HVAC load of 100VA, P2 with a total HVAC load of 200VA, and P3 with a total HVAC load of 300VA. Each panel’s portion of the total estimated demand (350 VA) is calculated based on their share of the total HVAC load connected. Thus, P1 = 1/6, P2 = 1/3, and P3 = 1/2 or 58.3 VA, 116.7 VA, and 175 VA, respectively. See Demand Factors.
   HVAC Connected	The sum of the HVAC loads connected to the panel
   Lighting Total Estimated Demand	The portion of the total Lighting load, adjusted for demand factor, connected to this panel. See the example for HVAC Total Estimated Demand. See Demand Factors.
   Lighting Total Connected	The sum of the Lighting loads connected to the panel
   Total Estimated Demand	The total load, adjusted for demand factor, connected to this panel. See the example for HVAC Total Estimated Demand. See Demand Factors.
   Distribution System Types	Distribution System specified for this panel
   Electrical Data	Voltage and number of poles feeding the panel.
