Circuit Properties

Use this tool to view or edit properties for the selected circuit. Although you can view detailed information about a circuit, such as load current, and circuit length, only the following parameters can be modified:

• Load Name - You can enter a name that will appear as the Load Name in the panel schedule for the panel where this circuit is connected.
• Rating - The current rating for the circuit. A warning displays when the load for a circuit exceeds 80% of the specified value for Rating.
• Wire Type - You can select a wire type for the circuit from the types specified in the Electrical Settings dialog.

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

   Parameter	Description
   Circuit Number	Circuit number on the panel where the circuit is assigned
   Load Name	Name that will appear as the Load Name in the panel schedule for the panel associated with this circuit.
   Panel	Name of the panel where the circuit is assigned
   System Type	Type of system for this circuit (Lighting, Power)
   Load Classification	Type of load. Click to access the Load Classification manager.
   Number of Poles	When specified as a type parameter, devices added to this circuit must match this parameter.
   Rating	Current rating for the circuit. The current rating for the circuit is used to calculate the wire sizing. A warning displays when the load for a circuit exceeds 80% of the specified value for Rating.
   Voltage	When specified as a type parameter, devices added to this circuit must match this parameter.
   Frame	Frame rating for the circuit. The maximum value that a breaker's trip can be set to.
   Apparent Load	The real and reactive power used by the circuit (Apparent Current x Voltage)
   Apparent Load Phase A	The real and reactive power used by the Phase A (Phase A Apparent Current x Voltage)
   Apparent Load Phase B	The real and reactive power used by the Phase B (Phase B Apparent Current x Voltage)
   Apparent Load Phase C	The real and reactive power used by the Phase C (Phase C Apparent Current x Voltage)
   Apparent Current	Total current for the circuit. For single phase, Apparent Current = (Apparent Load/Voltage). For 3-phase, Apparent Current = Apparent Load/(Voltage x )
   Apparent Current Phase A	Total Phase A current for the circuit. Apparent Current Phase A = Apparent Load/(Voltage x )
   Apparent Current Phase B	Total Phase B current for the circuit. Apparent Current Phase B = Apparent Load/(Voltage x )
   Apparent Current Phase C	Total Phase C current for the circuit. Apparent Current Phase C = Apparent Load/(Voltage x )
   True Load	Actual power (energy) used by the circuit. True Load = Voltage x True Current x Power Factor
   True Load Phase A	Actual power (energy) used by Phase A. True Load Phase A = Voltage x True Current Phase A x Power Factor
   True Load Phase B	Actual power (energy) used by Phase B. True Load Phase B = Voltage x True Current Phase B x Power Factor
   True Load Phase C	Actual power (energy) used by Phase C. True Load Phase C = Voltage x True Current Phase C x Power Factor
   True Current	Actual current for the circuit. True Current = True Load/Voltage
   True Current Phase A	Actual current for Phase A. True Current Phase A = True Load Phase A/Voltage
   True Current Phase B	Actual current for Phase B. True Current Phase B = True Load Phase B/Voltage
   True Current Phase C	Actual current for Phase C. True Current Phase C = True Load Phase C/Voltage
   Voltage Drop	The difference between the voltage applied and the voltage consumed on the circuit.
   Power Factor	The difference between Apparent Load and True Load, expressed as a decimal. Power Factor = True power/Apparent power
   Power Factor State	Lagging or Leading, depending on whether the load is inductive or capacitive. Loads are typically inductive, which results in a lagging power factor state.
   Balanced Load	Indicates whether the load is distributed evenly between the phases.
   Length	Total length of the wire runs in the circuit. Length is calculated as the sum of distances along the X, Y, and Z axes. See Wire Length Calculation.
   Wire Type	Type of wire used for the circuit, selected from the wire types specified in Electrical Settings. The type of wire selected for the circuit affects the wire sizing calculation. See Wiring Types.
   Wire Size	Displays left to right as the number and size of hot conductors, neutral conductors, and ground conductors. Calculated based on the wire type, correction factor, and circuit rating to maintain less than a 3% voltage drop. See Voltage Drop Calculation.
   # of Runs	The number of parallel conductors required to supply the circuit.
   # of Hot Conductors	Number of hot conductors. 1-pole circuits have 1 hot conductor, 2-pole circuits have 2 hot conductors.
   # of Neutral Conductors	Number of neutral conductors.
   # of Ground Conductors	Number of ground conductors.
   Number of Elements	Number of devices (connectors) that are connected to the circuit.
   Receptacles Connected	The total load of the connected devices assigned to a receptacle.
