Do I need a separate MCB for the SPD?
No – these boards use a single-module SPD that doesn’t require a separate MCB, saving space.
Are these compliant with the 18th Edition?
Yes – all models meet BS 7671:2018 Amendment 2 requirements for surge protection.
What’s the benefit of a Type 2 SPD?
It protects circuits and connected equipment from transient overvoltages caused by lightning strikes or switching events.
- Incoming Device: 100A main switch
