Electrical 5.2 Features


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.


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:

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.

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:

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.


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.


Rename: When you rename a piece of circuited equipment, the circuit description automatically updates to reflect the new name.


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.
