Customization--Labels and Schedules.Fault Current Schedule Label Display and Order dialog box

See the Common Label and Schedule Information section for more information on using the Move Up and Move Down buttons and the Key, Label, Width, Display, and Schedule Title fields.

AIC Rating: The AIC rating for the device. You specify this value for the device based upon the calculated fault value.

Device: The one-line device that the row displays fault information about. Devices are listed in the order they are connected, starting at the utility. Devices that are connected to other devices are indented to indicate their relationship. If the names of the devices extend beyond the edge of the column because of the indentation, increase the width of the column.

Direct Motor: Fault: The fault in amps of all the motors directly connected to this device at this device. The fault is 4 times the load of the motors. The XR ratio for motors is assumed to be 4. The motor is assumed to be directly connected to the panel. There is no reduction in the motor fault for the branch circuit length.

Direct Motor: KVA: The total load in kVA of all the motors directly connected to this device. The fault from motors connected to other devices is reduced based upon the feeders connecting the devices.

Direct Motor: R: The resistance of all the motors directly connected to this device.

Direct Motor: X: The reactance of all the motors directly connected to this device.

Fault: The total fault in amps at the device, including the fault from the utility and the fault from any motors in the system.

Fed From: Device: The device that this device is connected to. It is the device upstream from this device that is closer to the utility.

Fed From: Fault: The fault in amps at the device that this device is connected to.

Fed From: R: The resistance at the device that this device is connected to.

Fed From: X: The reactance at the device that this device is connected to.

Feeder: Length: The length of the feeder to this device.

Feeder: R: The resistance of the feeder to this device based upon the resistance per 1000 feet of the feeder and the actual length of the feeder.

Feeder: R / 1000': The resistance of the feeder to this device per 1,000 feet.

Feeder: Size: The wire size of the feeder connected to this device. This column lists the wire size of the phase conductors only.

Feeder: X: The reactance of the feeder to this device based upon the reactance per 1000 feet of the feeder and the actual length of the feeder.

Feeder: X / 1000': The reactance of the feeder to this device per 1,000 feet.

Line-to-Neutral Volts: The line-to-neutral voltage for the device.

Total Motor: Fault: The fault in amps of all the motors in the system at this devices.

Transformer: Fault at Primary: The fault in amps at the primary of the transformer. This fault is based upon the primary voltage, not the secondary voltage.

Transformer: KVA: The size of the transformer in kVA. Blank if the device is not a transformer.

Transformer: R: The resistance at the primary of the transformer.

Transformer: X: The reactance at the primary of the transformer.

Transformer: XR Ratio: The transformer XR ratio. Blank if the device is not a transformer.

Transformer: Z%: The transformer impedance percentage. Blank if the device is not a transformer.

Utility: Fault: The utility fault in amps at the device. Use this column instead of the Fault column if you do not want to include motor contributions in your fault calculations.

Utility: X: The reactance at the device from the utility current.

Utility: R: The resistance at the device from the utility current.
