Description
Where do you actually need to install low smoke cables?
It’s a question that comes up on almost every project, and the answer isn’t always as simple as “in escape routes.”
In this video, we break down:
• Why low smoke cables exist
• What Building Regulations Part B expects
• How BS 7671 applies to escape routes and public areas
• Where these requirements appear on drawings and specifications
• Which parts of an electrical installation must use LSZH or LSNH cable
• And where flexible plug and play systems fit into all of this
We also look at how modular lighting systems, like Flex7, simplify compliance by using LSNH cable across their entire range.
If your installation includes ceiling-mounted plug-in leads or distribution boxes, the cable choice matters just as much as the fixed wiring.
