In Autodesk Revit MEP Electrical Design, the System Browser is used to analyze and verify electrical systems, including panelboard connections, circuit hierarchies, and connected loads.

From the exhibit, the Properties palette shows that the selected equipment is a Lighting and Appliance Panelboard (208V MLO, 100A), named P4. To determine the parent panel that feeds Panel P4, we refer to the System Browser, which organizes the entire electrical distribution network hierarchically under the Electrical discipline.

In the System Browser on the right, under the Electrical category, we can observe that Panel P4 is nested directly under Panel P2. This organization indicates that P4 is circuited to (or fed from) Panel P2.

According to the Revit MEP 2011 User’s Guide, Chapter 4, “Electrical Systems—Using the System Browser,” it states:

“The System Browser displays electrical systems in a tree structure. Each subpanel or device listed beneath a main panel is connected to that panel through an electrical circuit. When a panelboard appears under another, it indicates the subpanel is fed from that parent panel.”

This is further reinforced in Smithsonian Facilities Revit Electrical Template Documentation (April 2021), Section 8.3 “Documentation Views,” which describes:

“Panel schedules and browser hierarchies show the distribution sequence. Subpanels appear indented beneath their source panel, indicating electrical dependency and circuit assignment.”

Therefore, by interpreting both the Revit interface and Autodesk’s documentation, Panel P4 is a subpanel connected to Panel P2, confirming that its electrical feed is assigned from Panel P2.

Final Verified Answer: B. Panel P2

In Autodesk Revit Electrical Design, lighting control systems such as single-pole, three-way, and four-way switches are managed using Switch Systems. These systems logically connect lighting devices (switches) to the lighting fixtures they control. For multiple switches (like three-way configurations) to be part of the same control circuit, they must share the same Switch ID value.

In the exhibit, the electrical designer is attempting to add a three-way switch to the existing switch system labeled “b”, but Revit does not allow it. The reason is that the Switch ID parameter of the new switch does not match the Switch ID of the system it is intended to join.

The Switch ID acts as the unique identifier that links all switches controlling the same group of fixtures. If the IDs differ (for example, “b3” versus “b”), Revit interprets them as belonging to separate systems and prevents them from being grouped together.

The Autodesk Revit MEP User’s Guide – Electrical Systems: Lighting and Switch Systems explains this clearly:

“Switch systems are organized by Switch ID. All switches controlling the same lighting circuit must have identical Switch ID values. Revit will not allow a switch to be added to an existing system if its Switch ID does not match that system’s identifier.”

To fix this, the designer must:

1️⃣ Select the three-way switch.

2️⃣ In the Properties palette, locate the Switch ID parameter.

3️⃣ Change its value to match the target switch system’s ID (in this case, “b”).

Once both switches share the same Switch ID, Revit will successfully include them in the same Switch System.

The warning message — “Can’t create this kind of element in this view in the current mode” — appears when an electrical designer attempts to place a Generic Annotation family inside a model family (e.g., a data device or electrical fixture) that is not configured to host annotation elements.

According to the Revit Electrical Design documentation, Generic Annotation families are 2D annotation elements, and therefore, cannot be created or viewed in 3D model views unless configured as “Shared.” The official guide clarifies:

“You can create generic annotation families and nest them inside host model families so that the annotations display in the project.”

However, this only functions correctly if the annotation is enabled to act independently within the host:

“To allow a nested annotation to be visible and editable when placed in a host model family, the nested annotation must be set to Shared before loading it into the host.”

If the nested annotation is not set to Shared, Revit cannot create or display it in the host’s model view, triggering this exact warning.

Thus, the correct workflow is:

Open the Generic Annotation family in the Family Editor.

Go to Family Category and Parameters.

Check the box “Shared” under Family Parameters.

Save and reload the family into the host electrical device family.

Other options—changing view level, detail level, or annotation orientation—do not resolve this placement restriction.

In Revit Electrical Design, the Selection Box tool is used to quickly isolate and display selected components in a cropped 3D view. When an electrical designer selects conduits or devices in a model and chooses Selection Box from the Modify tab, Revit automatically generates a 3D view bounded tightly around the selected elements, helping coordinate routing in confined or congested spaces.

According to the Revit MEP User’s Guide under “Creating 3D Views”:

“Use the Selection Box tool to create a 3D view that isolates selected elements. Revit automatically crops the view extents to the selected geometry.”

This feature is critical in multidisciplinary coordination because it allows the electrical designer to review specific conduits, cable trays, or lighting paths in context without manually adjusting view boundaries.

In contrast:

Default 3D View (Option B) shows the entire model.

Scope Box (Option C) controls view extents in 2D views or view templates, not instant isolation.

Section Box (Option D) is manually adjusted within an existing 3D view but does not automatically generate a cropped view around selected elements.

Therefore, the Selection Box is the correct and most efficient tool for this task.

In Autodesk Revit Electrical Design, the Circuit Number for a branch circuit in a panelboard is automatically generated based on the Circuit Naming Scheme specified in the project’s Electrical Settings. This naming scheme defines how each circuit is labeled by combining predefined fields such as Panel Name, Slot Index, and Phase Label.

From the exhibit, the Circuit Naming Parameter setup is configured as:

Name

Prefix

Sample Value

Suffix

Separator

Panel

Panel

Panel

—

“-”

Slot Index

Slot Index

Slot Index

—

“/”

Phase Label

Phase Label

Phase Label

—

—

The panelboard properties show that its Circuit Naming method is set to PanelSlotPhase, which means that Revit will generate circuit numbers using the following structure:

[Panel Name] – [Slot Index] / [Phase Label]

From the exhibit:

Panel Name: P1

Slot Index (Breaker Position): 1 (since the question refers to the first breaker position)

Phase Label: A (default value for the first phase in a three-phase 120/208V Wye system)

Therefore, the Circuit Number for a single-pole circuit in the first breaker slot will be:

✅ P1-1/A

This follows Revit’s documented logic for circuit naming. According to the Autodesk Revit MEP User’s Guide (Chapter 17 “Electrical Systems”):

“The circuit numbering format is controlled by the Electrical Settings > Circuit Naming template. The default scheme combines panel name, circuit number, and phase label, using the separators defined by the user.”

Furthermore, the Smithsonian Facilities Revit Template User’s Guide confirms:

“In the default electrical configuration, circuit numbers use the format [Panel Name]-[Circuit Number]/[Phase], such as ‘P1-1/A’ for the first single-pole circuit on phase A.”

Hence, based on the provided configuration and standard electrical setup, the correct circuit number for the first single-pole breaker position in panelboard P1 is P1-1/A.

In Autodesk Revit Electrical Design, the Interference Check tool allows designers to detect physical conflicts between elements in the current model and linked models, ensuring coordination between architectural, structural, and MEP systems.

According to the Revit MEP User’s Guide (Chapter 45 “Interference Checking”):

“You can check for interferences between elements within a single project or between elements in the host project and linked models. In the Interference Check dialog box, you can specify categories from the current project and from linked Revit models.”

The dialog box shown in the image displays two selection lists:

The left-hand side represents categories from the current electrical project.

The right-hand side represents categories from the linked structural model (STRUCTURE.rvt).

Since the task is to check for clashes between conduits (electrical) and beams (structural), the designer should select:

“Conduits” under Categories from Current Project (the electrical model).

“Beams” under Categories from STRUCTURE.rvt (the linked structural model).

As the guide explains further:

“Interference checking identifies intersections or overlaps between the geometry of selected categories. For MEP users, this is commonly used to check for clashes between ducts, pipes, or conduits and architectural or structural elements.”

This process ensures early detection of coordination issues before construction documentation. The designer can then review results through Coordination Review, isolate elements in 3D, or tag affected areas for correction.

Incorrect Options:

Selecting both categories from the same model (e.g., Electrical and Conduits) would only check within that model.

Choosing unrelated linked files (e.g., ARCHITECTURE.rvt) would not detect clashes with the structural beams.

In Revit, when editing a family in the Family Editor and reloading it into a project, Revit handles type changes using specific update rules. Types that are renamed overwrite their earlier version in the project because they retain the same internal type ID. Types that are added to the family also appear in the project once reloaded.

Initially, the family contains two types:

Above Counter

Plain

The changes made in the Family Editor are:

1️⃣ Rename Plain → Standard

2️⃣ Add a new type named GFCI

According to documented Revit behavior for type updates:

“When a family is reloaded into the project, any renamed family type replaces its previous version while maintaining its parameter assignments. Newly created types are added as additional family types available for placement within the project.”

Therefore:

Plain no longer exists because it was renamed

Standard now exists in its place

GFCI is added as a new family type

Above Counter remains unchanged

Thus, the family in the project now contains:

✅ Above Counter

✅ GFCI

✅ Standard

📘 This matches answer choice:

B. Above Counter, GFCI, Standard

In Autodesk Revit workshared projects, it is common for teams from multiple disciplines (architecture, structure, MEP) to collaborate using linked Revit models. Sometimes, an electrical designer may wish to hide or unload the linked architectural model only for their local session, without affecting how other team members see it.

Revit provides the “Unload for Me” option specifically for this purpose.

According to the Autodesk Revit MEP User’s Guide (Chapter: Worksharing – Managing Linked Models):

“When working in a shared model environment, you can unload a link temporarily from your local file using the Unload for Me command in the Manage Links dialog. This action affects only your local copy and does not impact other users working on the project. The link remains loaded for all other team members.”

This means that using Manage Links → Select the architectural link → Click Unload for Me, the designer can remove the visual presence of the architectural model from all of their views without impacting the rest of the team. The link remains active in the central model, and other disciplines will continue to see it as usual.

Here’s a breakdown of the incorrect options:

B. Remove: Permanently removes the link from the project, affecting all users — not allowed in a team collaboration environment.

C. Unload: Temporarily unloads the link for everyone upon synchronization with the central model.

D. Unload For all users: Explicitly unloads the link globally; all users lose access to the link after the next sync.

Therefore, the correct process for the electrical designer to hide the architectural link only for themselves is:

➡️ Manage Links → Select architectural link → Click “Unload for Me.”

In Autodesk Revit, phasing allows designers to track existing, demolished, and new elements across different project stages. Every model element includes two key phasing parameters:

Phase Created — defines when the element was built or introduced.

Phase Demolished — defines when the element is removed or demolished.

In the provided exhibits:

The project contains two phases: Existing and New Construction.

The receptacle’s Phase Created parameter is set to Existing, indicating it belongs to the pre-existing building condition.

The architectural wall hosting the receptacle is to be demolished during New Construction.

When a view’s Phase is set to New Construction and its Phase Filter is configured to show demolition, only elements whose Phase Demolished equals New Construction will appear as to be demolished. Therefore, the electrical designer must set the receptacle’s Phase Demolished value to New Construction so that it graphically displays as a demolished element in the demolition plan.

As explained in the Autodesk Revit MEP User’s Guide – Phasing and Coordination:

“Elements created in one phase and demolished in a subsequent phase must have their ‘Phase Demolished’ parameter set to that later phase to display properly in demolition views.”

Thus, to correctly coordinate with the demolition of its host wall, the receptacle must be flagged for demolition during New Construction.
