What is Riser?
A riser is an essential component in multi-story residential or commercial buildings, referring to the vertical portion of an electrical installation that carries power, communication cables, or plumbing systems from one floor to another. In the electrical context, risers are typically conduit runs or cable assemblies that provide power distribution between floors via electrical panels or subpanels.
Electricians often install risers in dedicated shafts, known as riser closets or riser rooms, to ensure they remain accessible for maintenance and are safely separated from other building systems. Proper riser installation is critical for compliance with building codes and fire safety regulations, especially since they often pass through fire-rated floors and walls.
For example, in a high-rise apartment complex, the main electrical service might enter the building at ground level and be distributed to each floor through a vertical riser. This system ensures efficient delivery of power while protecting cables and maintaining system integrity.
