What it represents
A switchgear-panel object represents the equipment envelope and interfaces used when arranging a switchroom or substation. The manufacturer and panel configuration establish the physical dimensions, cable entries, access sides and other installation information.
The original envelope illustration is unscaled and has no manufacturer dimensions. Follow the cited public resources to the exact product, then use its current drawing and installation information for engineering work.
How to read it
- Read plan and elevation views together.
- Identify the actual panel configuration before placing its footprint.
Information to show or reference
- Reference the current product GA.
- Identify cable interfaces and access sides.
- Link the SLD equipment identifier.
A distinction that matters
The panel envelope is a physical object; the breaker or switch symbol inside an SLD is an electrical representation.

About this graphic
This illustration was authored independently by Elora Grid to explain the concept. It is not reproduced from a customer drawing, an official standard graphic or a manufacturer CAD file. Its correspondence to an exact IEC or IEEE symbol identifier has not been certified.
SVG and DXF downloads contain this original artwork. DXF uses unscaled drawing units; a GA envelope supplies no product dimensions, clearances or fabrication information. Original artwork is available under CC BY 4.0. Third-party references retain their own terms.
