    Need to source Type B 3-phase distribution & 3P MCBs for EVSE, 1P RCBOs etc. so my sparky can install. A 6-way 3P board will suffice. Wondering what the general concensus is. Say, Contactum at the cheaper end vs Schneider Acti9 at the upper end. Drawn towards the Schneider as super neat...

    UK MCB type confusion.

    I've noticed at my grandparents house that all the MCB's in the consumer unit are all type C, every single one of them. Including the ring final circuits and lighting (there's no fluorescent lights in the house at all). The house isn't that old as well. Maybe about 16 years old. With me being a...

    Who makes this: type B, TP+N panels for DIN rail breakers and dual RCDs ?

    Who makes a TP+N panel, bigger than a consumer unit, for example, 14-way (with space for 12 or 14 three-phase breakers). It should feed its outgoing breakers using bus bars, not wires. (I call this a Type B panel) And it should be usable for Dual RCDs, one for the left side of the panel and one...
