This section describes how to use equipment. Equipment is used to model individual electrical connections that are typically not repeated in the design. Mechanical equipment and kitchen equipment are both examples of items that should be modeled as equipment. Equipment can be inserted on the drawing or just exist in the database. Training Videos The values that can be specified for equipment are listed below. All of these values must be set for each piece of equipment. Unlike receptacles and light fixtures, values cannot be pulled from a schedule. Group: The group that the piece of equipment is in. All of the equipment in a group are displayed in a single list. For more information about equipment groups, see the Equipment Projects Groups section. Equipment Callout: The name of the piece of equipment. The callout is used to label the equipment on the drawing and in the equipment list. Panel Description: The value that is displayed in the circuit description for the circuit that the equipment is connected to. There are two options for this field:
Circuit: The circuit to which the equipment is connected. Total Connected Load (kVA): The sum of the four connected loads on the piece of equipment in kVA. Total Demand Load (kVA): The sum of the four calculated loads on the piece of equipment in kVA. Total Connected Load (Amps): The sum of the four calculated loads on the piece of equipment in amps. This load depends upon both the load in kVA and the voltage of the equipment connection. Volts: The voltage for the piece of equipment. Ground: Whether the equipment requires a ground wire. Isolated Ground: Whether the equipment requires an isolated ground wire. If this is checked, an isolated ground wire is included in the wire callout for the branch circuit connected to this device. Elevation: The elevation of the equipment connection. See the Elevation section for more information. Layer System: See the Layer System section for more information. Drawing Note 1, Drawing Note 2: These notes will be displayed on the drawing below the equipment callout. Disconnect This section describes information about the disconnect. Some of this information is displayed on the drawing and some is displayed in the schedule. Schedule-only fields that you do not plan to display can be ignored. Type: The type of equipment connection and disconnect. The graphics that are displayed for the equipment on the drawing are dependent upon the equipment type. The type also determines whether a separate disconnect graphic is shown. The types available in this list can be modified using the Equipment Blocks command. Trip: The trip size of the disconnect, in amps. Set Curve: Press this button to configure the curve for the disconnect. The Select Curve dialog box will appear. Elevation: The elevation of the disconnect. This elevation is separate from the elevation of the equipment connection to allow for cases where the elevations are different. See the Elevation section for more information. NEMA Rating: The NEMA rating of the disconnect. This value is displayed on the drawing as a note on the disconnect block. Breaker and Wire Sizing FLA/ BCSC: The full load amps or branch circuit selection current. This value is used to size the breaker according to NEC 430.52 and 440.22, depending upon the Breaker Size setting. It is also used in one of the Wire Size options. MCA: The minimum circuit amps. This value is used to size the conductors to the equipment. It is not used in any of the calculations for the breaker size. MOCP: The maximum overcurrent protection. This value is used when sizing motor-compressor breakers, but not when sizing motor breakers. Breaker Size: How the breaker for the equipment is sized.
Set Curve: Press this button to configure the curve for the breaker. The Select Curve dialog box will appear. Frame Size: How the frame for the equipment is sized.
Wire Size: How the conductors for the equipment are sized.
Loads Load 1, Load 2, Load 3 and Load 4: An individual piece of equipment can have up to four separate assigned loads, each assigned to a different load type. See the Load Information section for more information. When the Horsepower field is set, the connected kVA for the load is calculated based upon NEC Tables 430.248 and 430.250. If the Connected field is later changed, the Horsepower field is reset to be blank. Set Load in Amps: Press this button to set the load on a piece of equipment in amps. The Set Load in Amps dialog box will appear. Connected Load 1, Connected Load 2, Connected Load 3, Connected Load 4: The current on each load in amps. Each field will be disabled if the corresponding load is disabled in the main equipment dialog box. Enter the load in amps for each connected load and press the OK button. The load will be converted to kVA based upon the Volts setting for the equipment and transferred to the corresponding Connected field. Schedule Information This section describes the Schedule Information button. The Schedule Information button is used to set information about the equipment that is displayed on the schedule. These values are not displayed or used anywhere else. Any fields you do not plan to display on the schedule can be ignored. Show in List: Whether the equipment is displayed in the list on the drawing. See the Insert Equipment List section for more information about the equipment list. Show in Fault Schedule: Whether the equipment is displayed in the fault schedule. See the Insert Fault Schedule section for more information about the fault schedule. Show in Voltage Drop Schedule: Whether the equipment is displayed in the voltage drop schedule. See the Insert Voltage Drop Schedule section for more information about the voltage drop schedule. Description: The description of the equipment. Location: The location of the equipment.
Sheet: The sheet on which the equipment is inserted.
Wire Callout: The callout of the branch circuit wire connected to the equipment.
Control Wiring: Information about the control wiring for the equipment. Provided By: Who is responsible for providing the equipment. Installed By: Who is responsible for installing the equipment. Schedule Note 1, Schedule Note 2, Schedule Note 3: These notes appear on the equipment schedule. See the Schedule Notes section for more information. Equipment AIC Rating: The ampere interrupting capacity (AIC) rating for the device. This value is not automatically calculated. It is important to specifically choose this value for all of the equipment in the project. When the Custom value is selected, a second Equipment AIC Rating field is available for manual input. Fuse Size: The fuse size of the disconnect. Fuse Type: The fuse type of the disconnect. Description: The description of the disconnect. Provided By: Who is responsible for providing the disconnect. Installed By: Who is responsible for installing the disconnect. Schedule Note 1, Schedule Note 2, Schedule Note 3: These notes appear on the equipment schedule to describe the disconnect. See the Schedule Notes section for more information. Description: The description of the starter. Thermal Overload: The thermal overload of the starter. NEMA Size: The NEMA size of the starter. NEMA Enclosure: The NEMA enclosure of the starter. Provided By: Who is responsible for providing the starter. Installed By: Who is responsible for installing the starter. Schedule Note 1, Schedule Note 2, Schedule Note 3: These notes appear on the equipment schedule to describe the starter. See the Schedule Notes section for more information. One-Line Diagram Settings This section describes the One-Line Diagram Settings button. The One-Line Diagram Settings button is used to set the blocks for the equipment when it is displayed on the one-line diagram. Show on One-Line Diagram: Whether the equipment is displayed on the one-line diagram. Most equipment will not have this box checked. When this box is not checked, the equipment will not be available to be inserted on the one-line diagram. Initial Equipment Connection Block: The block used on the drawing for the equipment. The Set Default button allows you to change the Default equipment connection block in the One-Line Diagram options section. Disconnect Block: The block used on the drawing for the disconnect. The Set Default button allows you to change the Default equipment disconnect block in the One-Line Diagram options section. OCP Block: The block used on the drawing for the OCP.<Use upstream distribution equipment OCP block> uses the same OCP block as the upstream distribution equipment. |
