What type of loads can the 32 A circuit support?
It’s suitable for heavier single-phase equipment such as EV chargers, air compressors, or heaters. Ensure the cable and supply are sized appropriately for the load.
Can I install this outdoors?
Yes – the IP65 rating ensures full weather resistance when properly sealed with cable glands. Ideal for garages, garden offices, and external workshops.
Does it include RCD protection?
No – it features a 100 A main switch incomer. For RCD-protected versions, see our RCD incomer models.
Is this board pre-wired?
Yes – it arrives pre-assembled with main switch, MCBs, and bars fitted. You only need to connect the supply and outgoing circuits.
Can I downgrade to a smaller MCB setup?
If you need a lighter setup, consider the 6A / 20A or 6A / 16A versions instead.
