Design Master Electrical RT 1.4

Released July 9, 2019.

The following is a list of new and updated features in Design Master Electrical RT 1.4.

Wire Length Make-up

The Feeder Make-up option has been expanded from a single project value. The additional make-up settings provide greater control of calculated wire lengths.

Wire length make-up is additional length added to calculated distances between devices.

Feeder Length Make-up: Each piece of distribution equipment can have a separate feeder length make-up assigned.

Branch Circuit Length Make-up: Branch circuits can now have make-up included in the calculated length. A default branch circuit make-up length can be set for the project. The branch circuit make-up length can be set for each circuit on a piece of distribution equipment. Finally, the branch circuit make-up length can also be set for each individual branch circuit.

 

Arc-Flash Calculation

The arc-flash calculation has been updated to use IEEE Std 1584-2018.

 

Branch Circuit Isolated Ground Wires

An isolated ground wire can be included on branch circuit devices. Any circuits that include a device with an isolated ground will include an isolated ground in the wire callout.

The isolated ground can be set in the family using the Family Edit command and on instances using the Instance Edit command.

 

Revit 2020

Revit 2020 is supported.

Feed Through Lugs: The new feed through lugs feature in Revit 2020 works with the one-line diagram created by Design Master Electrical.

To create a connection using feed through lugs, enable the Feed Through Lugs parameter in the upstream panel, then set the Connection Type for the downstream panel to Feed Through Lugs. The Lugs field for the upstream panel will be set to Feed Through.

To create a connection using top lugs, enable the Feed Through Lugs and SubFeed Lugs parameters in the upstream panel, then set the Connection Type for the downstream panel to Feed Through Lugs. The Lugs field for the upstream panel will be set to Double. Revit does not currently have a way to specify whether the connection uses the subfeed lugs. The software will assume that if the subfeed lugs exist, that is the connection type you intend to use.
