Load Information

Loads on devices are defined by the following fields.

  •  Panel Description: The description shown on the panel schedule for the load. Each receptacle and low voltage device load can have a different description.

    This field is not used for equipment loads. All of the equipment loads use the single Panel Description field for the equipment.

  •  Load Type: ▾ The type of load. The calculated load for each load type is handled differently.

    •  Lighting The calculated load is fixed at 125% of the connected load.
    •  Single Motor The calculated load is fixed at 125% for the largest single motor. The calculated load of all of the other single motor loads is fixed at 100%.
    •  Multiple Motors The calculated load is fixed at 100% for multiple motors. If there are no single motor loads, the largest multiple motors load is treated as the largest single motor load and the calculated load for that motor is fixed at 125%.
    •  Receptacle The calculated load is fixed at 100% of the first 10 kVA and 50% of the load after that.
    •  Continuous The calculated load is fixed at 125% of the connected load.
    •  Heating The calculated load is fixed at 125% of the connected load.
    •  Cooling, Single Motor The calculated load is fixed at 125% for the largest single motor. The calculated load of all of the other single motor loads is fixed at 100%.
    •  Cooling, Multiple Motors The calculated load is fixed at 100% for multiple motors. If there are no single motor loads, the largest multiple motors load is treated as the largest single motor load and the calculated load for that motor is fixed at 125%.
    •  Heating and Cooling Motor The calculated load is fixed at 125% of the connected load.
    •  Noncontinuous The calculated load is fixed at 100% of the connected load.
    •  Kitchen The calculated load is based upon the number of pieces of kitchen equipment, using NEC Table 220.56. The number of devices represented by the load is entered in the Demand Factor field.
    •  Diverse The calculated load is based upon the specified demand factor. The Demand Factor value is a percentage applied to the connected load (for example, enter 0.8 for 80% of the connected load).
    •  Custom 1 The calculated load is based upon the Custom Load 1: Calculation Method ▾ option. See the Circuits, Load Types, and Wire Sizes options section for more information.
    •  Custom 2 The calculated load is based upon the Custom Load 2: Calculation Method ▾ option. See the Circuits, Load Types, and Wire Sizes options section for more information.
    •  Small Appliance The calculated load is fixed at 125% of the connected load.
    •  Laundry The calculated load is fixed at 125% of the connected load.
    •  Appliance, Continuous The calculated load is based upon the number of appliances, using NEC Table 220.53. The number of devices represented by the load is entered in the Demand Factor field.
    •  Appliance, Noncontinuous The calculated load is based upon the number of appliances, using NEC Table 220.53. The number of devices represented by the load is entered in the Demand Factor field.
    •  Appliance Motor The calculated load is fixed at 125% of the connected load.
    •  Electric Dryer The calculated load is based upon the number of appliances, using NEC Table 220.54. The number of devices represented by the load is entered in the Demand Factor field.
    •  Electric Cooking The calculated load is based upon the number of appliances, using NEC Table 220.55. The number of devices represented by the load is entered in the Demand Factor field.
    •  Dwelling Unit Heating The calculated load is based upon the number of heating units, using NEC 220.82(C). The number of devices represented by the load is entered in the Demand Factor field.
    •  Dwelling Unit Cooling, Single Motor The calculated load is fixed at 125% for the largest single motor. The calculated load of all of the other single motor loads is fixed at 100%.
    •  Dwelling Unit Cooling, Multiple Motors The calculated load is fixed at 100% for multiple motors. If there are no single motor loads, the largest multiple motors load is treated as the largest single motor load and the calculated load for that motor is fixed at 125%.
    •  Dwelling Unit Heating and Cooling Motor The calculated load is fixed at 125% of the connected load.
    •  Marina / Mobile Home / RV The calculated load is based upon the number of marina receptacles, mobile home lots, or RV sites. The number of units represented by the load is entered in the Demand Factor field.

  •  Horsepower: ▾ The horsepower of the motor load. This field is only available for equipment. The Connected field will be set based upon the horsepower using NEC Table 430.248 for single-phase motors and NEC Table 430.250 for three-phase motors.

  •  Connected: The connected load in kVA.

  •  Demand: The connected load after the demand factor has been calculated. For most load types, this field will be disabled and filled in automatically based upon the connected load. It will be enabled for Custom 1 and Custom 2 if the Calculation method ▾ is set to Variable calculated load.

  •  Demand Factor: The multiplier used to calculate the demand load from the connected load. For most load types, this field will be disabled and automatically filled in. It will be enabled for the following load types:

    •  Kitchen
    •  Diverse
    •  Appliance, Continuous
    •  Appliance, Noncontinuous
    •  Electric Dryer
    •  Electric Cooking
    •  Dwelling Unit Heating
    •  Marina / Mobile Home / RV

    The value is the number of units of that load type.

    It will also be enabled for Custom 1 and Custom 2 if the Calculation method ▾ is set to Variable demand factor.
