When the Circuit Configuration dialog box opens, and you select Main
Disconnecting Means from the Circuit Elements tree structure, the Fused
Disconnect option is selected. If you select Insert, instead of Configure, to
insert the circuit without user prompts, the Fused Disconnect is used for the
main disconnecting means.
If you always want a different option selected or used as the default, this value
can be changed.
1 Open the Circuit Builder spreadsheet, ace_circuit_builder.xls.
2 Find the circuit category and type in the ACE_CIRCS sheet, for example
Category: 3ph Motor Circuit and Type: Horizontal - FVNR - non reversing.
3 Find the value in the SHEET_NAME column, for example 3ph_H. Open
the worksheet by selecting on the 3ph_H tab.
4 Find the circuit element by looking at the values in the COMMENTS and
UI_TITLE columns. For example, COMMENTS: Disconnecting Means and
UI_TITLE: Main Disconnect.
Notice there are multiple options for this circuit element as listed in the
UI_PROMPT_LIST column. The current default option is indicated by an
X in the UI_DEF column.
5 Move the X in the UI_DEF column to the row containing the option
you want as the default, for example Circuit Breaker. Make sure that only
one row for the group contains an X.
6 Save the spreadsheet.
Set up component auto-sizing
Circuit Builder can calculate the rating for components in the circuit based
upon some multiple of the full load amp value of the motor or load. For
example, the electrical code standard might state that a disconnect switch
must be rated not less than 115% of the load amperage. An expected maximum
load of 28 amps would require a disconnect switch rated at not less than 115%
of 28 amps, or 32.2 amps. If standard switch ratings are 30 and 60 amps, a 60
amp switch would be selected.
Such an automatic calculation can be accomplished by creating a relationship
between the call in the ANNOTATE_LIST field value in the
circuit codes sheet
on page 2006 of the circuit builder spreadsheet, and the MOTOR_I_* tables in
the
electrical standards database on page 2015.
