What it represents
Busbar trunking transports and distributes electrical power using a selected enclosed conductor system. The physical GA route can include straight sections, joints, bends and connection units defined by the manufacturer. The SLD represents the electrical connections rather than those physical details.
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
- Match the route and connection units to the selected product system.
- Link physical endpoints to the electrical equipment references.
Information to show or reference
- Reference the selected system and current product drawings.
- Identify joints, fittings and connection interfaces.
- Coordinate the electrical and physical endpoints.
A distinction that matters
An SLD busbar line is an electrical node; busbar trunking is an actual distribution assembly with defined geometry.
