Branch circuit device: Other

When the selected family instance has the type set to Branch circuit device: Other or has not been configured using the Family Edit command, this Instance Edit dialog box appears:

Instance Edit Dialog Box

branch-circuit-device-other-dialog-box

Device Type: The Device Type set for the family in the Family Edit command.

Family Name: The name of the Revit family for the selected instance.

Family Type: The type of the Revit family for the selected instance.

Circuit Description: The circuit description for the selected instance.

Use circuit description from family: Use the circuit description set for the family in the Family Edit command.
Set circuit description in instance: Enter a circuit description in the field provided.
Controlled by Revit: If Circuit description method in the Project Options command is set to Use Revit circuit descriptions, this field is disabled.

Load: The load of the selected instance as set in Revit.

Isolated Ground: Whether the branch circuit requires an isolated ground wire. If set to Yes, an isolated ground wire is included in the wire callout for the branch circuit connected to this device.

OCP Graphic: The graphic family used for the upstream OCP when the device is inserted on the one-line diagram. The values in this list are based upon the One-Line Diagram Feeder Graphics command.

Use upstream distribution equipment graphic: The Default Downstream OCP Graphic and Default Downstream OCP Type set in the upstream distribution equipment will be used.

OCP Type: The graphic type used for the upstream OCP. The values in this list are based upon the selected OCP Graphic.

Feeder ID Graphic: The graphic family used for the feeder ID when the device is inserted on the one-line diagram. The values in this list are based upon the One-Line Diagram Feeder Graphics command.

Default feeder group: The feeder ID graphic set for the group in the Project Feeder ID Schedule will be used.

Feeder ID Type: The graphic type used for the feeder ID. The values in this list are based upon the selected Feeder ID Graphic.

Show on AutoCAD One-Line Diagram: Whether to show the instance as an equipment connection on the one-line diagram created using the Export to AutoCAD command.

Default (No): If Device Type is set to Branch circuit device: Other, the default is to not show the device on the one-line diagram. If Device Type is later changed to Branch circuit device: Equipment connection, the family default value can be set to Yes or No. This setting will update to the family default value.
Yes: The instance will be shown on the one-line diagram.
No: The instance will not be shown on the one-line diagram.

FLA / BCSC: The full load amps (FLA) or branch circuit selection current (BCSC).

N/A: The default value. The device does not have an FLA or BCSC.
Custom: Specify the value for the FLA or BCSC in the field provided.

MCA: The minimum circuit amps (MCA).

N/A: The default value. The device does not have an MCA.
Custom: Specify the value for the MCA in the field provided.

MOCP: The maximum overcurrent protection (MOCP).

N/A: The default value. The device does not have an MOCP.
Custom: Specify the value for the MOCP in the field provided.

OCP Trip: How to size the breaker for the branch circuit to which the equipment is connected.

Size automatically (based upon load): The breaker is sized based upon 125% of the connected load. FLA / BCSC, MCA, and MOCP are all ignored.
Motor-compressor, <= MOCP: The breaker is sized to be less than the MOCP (see NEC 440.22(C)).
Motor-compressor, <= 175% of BCSC, <= MOCP: The breaker is sized to be less than 175% of the BCSC and less than the MOCP (see NEC 440.22(A) & (C)).
Motor-compressor, <= 225% of BCSC, <= MOCP: The breaker is sized to be less than 225% of the BCSC and less than the MOCP (see NEC 440.22(A) & (C)).
Motor, dual element fuse, <= 175% of FLA: The breaker is sized to be less than 175% of the FLA (see NEC 430.52).
Motor, dual element fuse, <= 225% of FLA: The breaker is sized to be less than 225% of the FLA (see NEC 430.52(C)(1) Exception No. 2(2)).
Motor, inverse time breaker, <= 250% of FLA: The breaker is sized to be less than 250% of the FLA (see NEC 430.52).
Specific ampacity: The breaker size is set to the specific size chosen from the list.

Select Breaker Curve: Press this button to configure the curve for the breaker. The OCP Device Settings dialog box will appear.

Conductor: How to size the conductors for the branch circuit to which the equipment is connected.

Size automatically (based upon breaker, or loads if breaker based upon motor): The conductors are sized automatically. The conductors are sized to match the breaker, or match the load if OCP Trip is set to one of the Motor choices.
Multimotor, >= MCA: The conductors are sized to be greater than the MCA (see NEC 440.35).
Motor-compressor, >= 100% of BCSC + 25% of max BCSC: The conductors are sized to be greater than 100% of the combined BCSC, plus 25% of the largest BCSC on the circuit (see NEC 440.32 & 33).
Size based upon loads: The conductors are sized based upon 125% of the connected load.
Size based upon breaker: The conductors are sized based upon the breaker size.
Specific ampacity: The wire size is set to the specific size chosen from the list.
