Revit 2020 has a new feature that will please Electrical designers. Feed through lugs are now incorporated into Revit for your electrical distribution system. Previously, electrical users had to utilize workarounds to represent this situation in their designs, so this will improve the documentation process and help with the electrical design.
As part of this new feature, Revit has added a new panel schedule template, which is called “Feed Through Lugs Panel“. This panel is available in the Electrical-Default.rte and the Systems-Default.rte templates. This panel template is accessible via the Managetab -> Settingspanel -> Panel Schedule Templates.
The process to actual set up the electrical panels to utilize the above Panel Schedule is shown below. Continue reading →
When working with a multi-story building, it is common to have identical electrical items on multiple floors and the designer desires to have the same circuits for those items replicated on each level. Doing so creates consistency between panel board circuits and reduces labor for circuiting each floor. An example of this is the restrooms, janitor closets, elevator lobby and other service areas in the core of a building where each of those rooms will have the same electrical needs for each floor level.
It is possible to copy the electrical devices and equipment from one floor level to multiple other floor levels and replicate the circuits for the new items. The electrical devices that were circuited together in the first level will be circuited together in the other levels. The Rating, Frame, and Load Name for the replicated circuit(s) will be the same as the original circuit(s).
Electrical symbol legends are a critical part of electrical design documents and everyone wants to have a Symbols List which automatically updates to show the actual electrical symbols that are placed in a project. That way, the only symbols that are on the list are ones that are actually placed in the model and the list does not include many unused symbols. It is actually possible to do this. When an electrical item gets added to the model, the symbol gets added to the symbol list.
For a long time, I have wished that there were better ways to organize schedules in Revit’s Project Browser, especially in project files with dozens of schedules. The recently released 2018.1 version of Revit does just that and allows me various ways to organize my schedules in a Revit project file. Different disciplines and different companies have varying quantities of schedules, so some users will appreciate this new feature more than users.
The following image shows grouping the schedules based upon working schedules and schedules that will be placed on sheets. This particular option is created by having 2 different View Templates for schedules – one for working schedules and one for schedules on sheets. Schedules are then grouped by View Templates.
Electrical designers can now get actual circuit lengths in Revit 2018. In previous releases, Revit would calculate the “X” plus “Y” distances plus the vertical distance in the circuit resulting in incorrect lengths. Revit now allows you to specify a path for the circuit, which can calculate for the circuit running along walls, ceilings, etc and other jogs to account for where the circuit conduit would actually run. Going through the process of specifying an actual path for receptacle or lighting circuits is probably overkill and won’t be performed by most electrical designers. However, specifying the actual path for an actual circuit length can make a big difference when calculating voltage drop for large electrical equipment.
I have run into a quirky situation with Revit electrical panel schedules that I want to pass along.
When using Revit MEP for electrical design, part of the process is creating circuits and then adding that circuit to a panel or switchboard. The Trip Rating of the circuit sets the size of the breaker on the panel or switchboard, so it is shown on the electrical panel or switchboard schedule appropriately. If the Trip Rating is changed, the breaker size automatically updates on the panel schedule. All is good.
The panel/switchboard schedule is then placed on a sheet for documentation/printing purposes.
The problem: Sometimes the updated Trip Rating does not update on the sheet although it is actually updated and correct in the panel schedule.
This creates a strange situation where the information shown on the sheet is not the same as the information shown in the actual panel schedule view.
Fortunately, when the project file is closed and then re-opened, the sheet will update to show the correct trip rating (breaker) size.
When using Revit for electrical design, using Panel Schedules should be an important part of your design process. Revit provides the user with some default panel schedule templates with the software, but most organizations modify the templates to function and appear the way that they desire. Revit allows the user to do quite a bit of customization to the templates, but be aware that there are still limitations to the customization ability and some nuances.
Revit Help has instructions for basic electrical template modification. In this article, we will look at some aspects of customizing a template that are not so obvious to the user.
