Installation notes
This board is supplied pre-wired and must be installed by a qualified electrician. It simplifies compliant protection for heat pump circuits requiring Type B RCD and SPD integration.
- Mount securely on a dry, internal surface using standard fixings
- Use rear or side knockouts for incoming and outgoing cables
- Ensure correct earthing and SPD bonding as per BS 7671
- Do not modify pre-wiring – contact us for custom builds if needed
FAQs
Is this board compliant for heat pump installs under the 18th Edition?
Yes. It includes a Type B RCD and a Type 2 SPD, both required for inverter-driven loads such as heat pumps. For standalone installs, see our Heat Pump RCD.
What’s the difference between the 8-way and 12-way versions?
The devices supplied are the same. The 12-way simply provides more DIN space for adding future RCBOs or MCBs.
Can I add RCBOs to this board?
Yes. Spare DIN ways are included for adding outgoing protection devices. For nuisance-trip resistance, see our High Immunity RCBOs.
How quickly can this be delivered?
Each unit is built to order and dispatched within 3 working days. For in-stock options, see our 6 Way Consumer Units.
