this cost is recovered many times over in reduced energy losses in the wiring
during the life of the installation.
NOTE The ace_electrical_standards.mdb file replaces the mcc.mdb file used in
previous versions of Circuit Builder.
The electrical standards database contains multiple tables used by Circuit
Builder.
Contains the values used to populate the
Select Motor on page
710 dialog box.
MOTOR
Contains the values used to populate the Select Load on page
711 dialog box. This table name can have an optional suffix to
relate it to a specific electrical standards code.
FEED
Options tables contain values defining defaults and options lists
specific to an electrical standard. For example, default to copper
wiring, AWG size standard, and feet for conductor length units.
OPT
Wire ampacity tables contain the ampacity ratings for different
conductor sizes and insulation temperature ratings.
AMP_{wire type}_{wire size stand-
ard}
Grounding conductor sizing tables contain the maximum ampa-
city ratings for different grounding conductor sizes. This inform-
AMPG_{wire type}_{wire size stand-
ard}
ation is used to retrieve the minimum grounding conductor size
and provide a selection list of larger sizes.
Wire insulation tables lists the insulation types, the maximum
temperature rating for each, and de-rating factors for each based
on a series of temperatures.
INSUL_{wire type}_{wire size stand-
ard}
Conductor Reactance/AC Resistance tables contain values used
to estimate single-phase and three-phase voltage drop values.
XL&R_{wire type}_{wire size stand-
ard}
Conduit/raceway descriptions list used with the XL&R_{wire
type}_{wire size standard} tables.
XL&R_DESC
Fill tables contain the ampacity de-rating factors used when
there is more than one current carrying conductor (power wiring,
FILL
not ground, neutral, or control wires) in the same conduit, duct,
or raceway.
