Equipment

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 exist just in the database.

Common Equipment Information

The values that can be specified for equipment are listed below. All of these values are set specifically for each piece of equipment. Unlike receptacles and light fixtures, there is no schedule for equipment, so there are no values pulled from the schedule.

Equipment Callout: Name of the piece of equipment. The callout is used to label the equipment on the drawing and in the equipment list.

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.

Circuit: The circuit the equipment is connected to.

Panel Description: The value that is displayed in the circuit description for the circuit that the equipment is connected to. There are two choices for this field:

Same as Equipment Callout: The description in the circuit on the panel schedule will be the equipment callout. This is the default setting. When this is selected, the Custom Panel Description field is disabled.
Custom: The description in the circuit on the panel schedule is set to a custom panel for this piece of equipment. When this is selected, the Custom Panel Description field will be enabled. The value entered in that box will be used for the description in the circuit on the panel schedule. Custom descriptions are most useful when you need to shorten the label that is displayed on the panel schedule.

Ground: Whether or not the equipment requires a ground wire.

Isolated Ground: Whether or not 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.

Show on One-Line: Check this box to display the equipment 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. For more information on one-line diagrams, see the Creating and Modifying One-Line Diagrams section.

Show in List: Check this box to display the equipment in the list on the drawing. For more information on the equipment list, see the Insert Equipment List section.

Volts: The voltage for the piece of equipment.

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 Demand 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.

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.

Motor-Compressor, MOCP (or loads if no MOCP): Breaker will be sized to match the MOCP. The FLA / BCSC value will be ignored. If no MOCP value is specified, the breaker is sized based upon the connected load of the device.
Motor-Compressor, 175% of FLA / BCSC, not to exceed MOCP: Breaker will be sized based upon 175% of the FLA / BCSC value. If that is larger than the MOCP, the MOCP value will be used. This is for NEC 440.22(A).
Motor-Compressor, 225% of FLA / BCSC, not to exceed MOCP: Breaker will be sized based upon 225% of the FLA / BCSC value. If that is larger than the MOCP, the MOCP value will be used. This is for NEC 440.22(A).
Motor, Dual Element Fuse, 175% of FLA: Breaker will be sized based upon 175% of the FLA / BCSC value. This is for NEC 430.52 dual element fuse breakers.
Motor, Dual Element Fuse, 225% of FLA: Breaker will be sized based upon 225% of the FLA / BCSC value. This is for NEC 430.52 dual element fuse breakers exception no. 2 (b).
Motor, Inverse Time Breaker, 250% of FLA: Breaker will be sized based upon 250% of the FLA / BCSC value. This is for NEC 430.52 inverse time breakers.
Size based upon loads: Breaker will be sized based upon the connected load of the device.
Specific breaker sizes: A list of all the possible breaker sizes for manually setting the breaker size.

Wire Size: How the conductors for the equipment are sized.

Motor-Compressor, MCA (or loads in no MCA): Conductors will be sized based upon the MCA. This is for NEC 440.33 and 440.35. If no MCA value is specified, the conductors are sized based upon the connected load of the device.
Single Motor-Compressor, 125% of BCSC: Conductors will be sized based upon 125% of the FLA / BCSC value. This is for NEC 440.32.
MOCP: Conductors will be sized based upon the MCA.
Size based upon loads: Conductors will be sized based upon the connected load of the device.
Specific wire sizes: A list of all possible conductor sizes for manually setting the conductor size.

Drawing Information

This section describes the information about the equipment that is displayed on the drawing.

Elevation: The elevation of the equipment connection. See the Elevation section for more information.

Layer System: See the Layer System section for more information.

Note 1 and Note 2: These two notes will be displayed on the drawing below the equipment callout.

Schedule Information

This section describes 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.

Description: The description of the equipment.

Location: The location of the equipment. When Default is selected, the name of the room where the equipment is inserted is displayed on the schedule.

When Custom is selected, the location can be manually entered. Using Custom is helpful when you have not inserted rooms in your project or you want a location other than the room name displayed.

Sheet: The sheet that the equipment is inserted on. When Default is selected, the name of the drawing file where the equipment is inserted is displayed on the schedule.

When Custom is selected, the sheet can be manually entered. Using Custom is helpful when the sheet the equipment is displayed on is different than the name of the drawing file it is inserted on.

Wire Callout: The callout of the branch circuit wire connected to the equipment. There are two choices for this field:

Default: When selected, the callout from the circuit is displayed on the schedule.
Custom: When selected, the wire callout can be manually entered.

The choices available in this list can be modified using the Equipment Blocks command.

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.

Fuse Size: The fuse size of the disconnect. This field is only displayed on the schedule.

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 430-18 and 430-150. If the Connected field is later changed, the Horsepower field is reset to be blank.

Set Load in Amps: Press this button is used to set the load on a piece of equipment in amps. The Set Load in Amps dialog box will be opened.

Equipment--Set Load in Amps dialog box

Connected Load 1, Connected Load 2, Connected Load 3, Connected Load 4: The current on each separate load in amps. These fields are disabled if the load is disabled in the main equipment dialog box.

Enter the load in amps for each connected load and press OK. The load will be converted to kVA based upon the Volts setting for the equipment and transferred to the corresponding Connected field.
