Electrical 5.2 Features
Panels
Panel to Panel Connections: The imbalanced load on the secondary
of a transformer is now carried to the upstream panel on the primary. In
the past, the load was transferred as a balanced load on the primary regardless
of balance on the secondary.
Automatic Transformer Breaker Sizing: The breaker size of the
transformer is sized automatically based upon the transformer KVA and
voltage. Changing either of these will change the breaker size of the
transformer. The breaker size can be manually changed after you set the
KVA and voltage.
Fault Calculation Warning: You are now warned if you have an upstream
breaker set to N/A.
Panel Dimensions: Panel dimensions can no longer be 0.
Feeder Neutral: The feeder neutral can be set to 200% of phase.
This will insert two neutral conductors, rather than doubling the size
of the neutral conductor. If you want to use a larger wire size, simply
set it manually.
Circuiting
Custom Wire and Conduit Sizing: Wire and conduit sizing is now
completely customizable. You can define multiple different sizing options
in a new standards file called dm_elec-wiresizing.txt. For example, you
may have an "all copper" standard, and a "copper - aluminum"
standard. Likewise, you can have a "60 degree C" standard and
a "75 degree C" standard. This is no limit to the number of
wire and conduit sizing tables you may create.
Loop Memory:
- Loops Only Removed When Uncircuited: Design Master
now strives as much as possible to not erase circuit loops when it does
not have to. Loops are only removed when a device is uncircuited.
- Draw Homerun: There are now two buttons for drawing homeruns. Draw Homeruns
and Loop works like the Draw Homerun button used to. It will draw a homerun
from the selected circuit, erase all of the existing loops, and redraw
the loops for you. Draw Homerun now only draws a homerun and ignores the
loops.
- Loop Devices Manually: We also modified Loop Devices Manually so that
you can more easily add one more device to a circuit that has already
had all of its loop locations tweaked. In this situation, you will want
to first circuit the device normally. Then, draw a loop from previously
circuited device to the device that you just circuited. The loop will
be drawn and any circuit callout labels will be cleaned up..
Homerun Labeling Options: There are new options available for
labeling homeruns. You can turn tick marks off and have it display a normal
circuit callout for #12 wires. Or, you can turn wire callouts off completely.
There is also an option to display a #10 next to a homerun that has been
upsized from #12 wires due to distance.
Circuit Limits: There are two options for setting circuit limits.
- Amp Limit: The first is a limit on the number of amps for a
circuit. When this option is set, Design Master will warn you whenever
you the circuit load amps exceed the limit. Turn this feature on when
you are circuiting devices that have a limit, such as light fixtures.
When you are circuiting other devices, you may turn this feature off.
- Total Receptacles Limit: The second limit is the number of
receptacles on a circuit. This limit can be on at all times. It will
warn you when you connect more than the desired number of receptacles
to a circuit.
Information While Circuiting: The load and breaker size of the
current circuit are listed at the command line while you are circuiting.
Grounded Circuits: Circuiting an ungrounded device to a grounded
circuit no longer removes the ground.
Circuiting Dialog:
- Information: More information is now displayed in the circuiting
dialog. The wire size of the currently selected circuit is displayed
at the top. For the current panel, the total connected KVA is displayed.
The amps, broken down by phase, are also displayed.
- Recalculate Panel Load Total: This button recalculates the
load total on the panel.
- Uncircuit All Connected Devices: This button uncircuits all
devices from this panel and removes all fixed loads. This is helpful
when you want to delete a panel quickly.
Update Circuit Labels: The multi-section panel callouts now match
the format used by other functions. The *2 and *3 are masked in the homerun
callouts so that only the main panel section of a multi-section panel
are displayed.
Switch Tick Marks: Tick marks on switch loops now go on the proper
layer, not layer 0.
Homerun Backbone: The homerun spine was renamed the homerun backbone
as a more intuitive description.. It has been improved to be less fussy
when looking for device to include. The backbone only needs to cross the
device, not pass near the insertion point of the device.
Circuit Callouts: When drawing a homerun without loops, you can
display the circuit callouts with or without the panel included.
Upsize #12 to #10: When upsizing #12 to #10 wire automatically,
you can now put a #10 as the homerun circuit callout in addition to the
tick marks.
Fixed Wire Size: Wire sizes can be locked in the N/A mode.
Tick Marks: Tick marks can be turned off and the full homerun
callout can be displayed for #12 wires.
Homerun Callouts: The wire callout on homeruns can be removed completely.
Devices
Trace Architect's Light Fixtures or Receptacles: There are two
new commands that allow you to quickly transfer a light fixture or receptacle
layout created by your architect. This feature saves time creating lighting
plans when the architect has already created the light fixture layout.
To use this feature, you first define your light fixtures or receptacles
in their schedule, then use the trace commands to map specific blocks
on the background to specific entries in the schedule. You then tell Design
Master which drawing to insert the devices on, and it creates the new
devices where the architect located them.
When the architect updates the layout, you can run the command again.
Light fixtures that are in the same place as before will not be reinserted.
Light fixtures that have been moved will be inserted in their new location.
You will need to cleanup light fixtures that are at old locations or that
have been removed.
Create Multi-Circuit Device: Multi-circuit devices are used to
model devices that are connected to more than one circuit. In Design Master,
we model them as two devices inserted directly on top of each other. This
new command simplifies the process of creating the extra device. Examples
of multi-circuit devices include: light fixtures with some lamps on an
emergency circuit, multi-circuit track lighting, and multi-circuit plugmold.
Non-rotating Text: Non-rotating text can be adding to device blocks.
J-Box Homeruns: Homeruns from j-boxes are put on the correct layer,
rather than layer 0.
Coordinate Receptacles / Light Fixtures with Schedule: These functions
have been removed since the functionality is now included with Coordinate
Drawing and Database function. If you need to coordinate these devices,
run the Coordinate Drawing and Database function instead.
Light Fixtures
Mirrored Light Fixtures: Mirrored light fixtures now work correctly
with outdoor photometric calculations. Previously, their rotation angle
was being calculated incorrectly.
Circuit Tag Layer: The circuit tags on light fixtures are now
set to the correct layer after the type of the light fixture is changed.
Spaces in Callouts: Light fixture callouts can now have spaces
within the text.
Light Fixture Schedule Field Width: The width of all of the fields
in the light fixture schedule has been increased so that it is wide enough
to accommodate all of the text in the field.
Light Fixture Dialog: The layout of the light fixture project
and master schedules has been improved to make it easier to read.
Automatic Light Fixture Callout Insertion: You can now have Design
Master automatically insert the light fixture callout for each fixture.
This is an option in the Options window. You will need to redefine your
light fixture blocks so that the insertion location for the callouts is
correct.
Equipment
Rename: When you rename a piece of circuited equipment, the circuit
description automatically updates to reflect the new name.
Receptacles
Circuit Description: When you edit the circuit description of
a receptacle, the circuit is automatically updated.
Receptacle Field Lengths: The receptacle dialog boxes now have
fixed limits on the edit boxes for fields that have a fixed length in
the database. This applies to the panel description, NEMA type, and the
notes. This will help a user avoid creating descriptions longer than allowed.
