The size is based upon 125% of the continuous load, and 100% or 125% of the noncontinuous load, depending upon the setting of the Size breakers to 100% of noncontinuous load option. See the Circuits, Load Types, and Wire Sizes section for more information on this option.
None: The circuit does not have a breaker. The breaker column in the distribution equipment schedule will display a slash and the number of poles (/1 or /2 or /3). No breaker size will be displayed.
Specific Size: The selected breaker size is used for the circuit.

Conductor Amps: Sets the size of the hot wires of the currently selected circuit.

Size Automatically: The hot wires are sized based upon the Breaker Size.
None: The circuit does not have a conductor wire. The wire callout for the circuit will be blank.
Specific Breaker Size: The hot wires are sized to match the breaker size chosen from the list.

Neutral: Sets the size of the neutral wire of the currently selected circuit. If the distribution equipment does not have a neutral, this field is disabled and set to None.

Size Automatically: The neutral wire is the same size as the phase wires as specified in the Conductor Amps field.
None: No neutral wire is included in the circuit. If the devices on the circuit require a neutral wire, this option is not available.
Specific Breaker Size: The neutral wire is sized to match the wire size chosen from the list.

Ground: The size of the ground wire of the currently selected circuit.

Size Automatically: The ground wire is sized based upon the Equipment Ground setting for the larger of the two breaker sizes specified in the Breaker Size and Conductor Amps fields. The ground wire will never be larger than the conductor wires.
None: No ground wire is included in the circuit.
Specific Breaker Size: The ground wire is sized to match the wire size chosen from the list.

Conduit Size: The size of the conduit of the currently selected circuit. The conduit fill percentage is displayed next to the Conduit Size field. Changing the conduit size will update the fill percentage.

Size Automatically: The conduit is sized automatically based upon the wires in the circuit. All conduits are sized using a 40% conduit fill (NEC Table 1).
None: No conduit is included for the circuit.
Specific Breaker Size: The conduit is sized to match the conduit size chosen from the list.

MCC Starter Size: The motor control center starter size. This field is enabled for circuits on motor control centers. It is disabled for all other distribution equipment types. The value is displayed in the motor control center schedule.

MCC Description: The motor control center description. This field is enabled for circuits on motor control centers. It is disabled for all other distribution equipment types. The value is displayed in the motor control center schedule.

Layer System: The layer system of the currently selected circuit. This layer system controls the layer that is used for the circuit callouts, homerun, and loops on the plan. It also controls the layer of the feeder wire on the one-line riser diagram if this circuit is shown there. See the Layer System section for more information.

Underground: Whether the circuit is underground. Different layers are used for aboveground and underground loops. The layer used for underground loops defaults to a dashed linetype, but this can be changed using the customization commands.
