RCD RATING VS. SERVICE FUSE RATING

[Nigel]

So the OP's wholesaler was wrong with their assertion that all RCCBs will need to be 100A rated.

My example is how I used to arrange all my dual RCD boards anyway, but not installed any for a while now.

You are correct. I suppose the supplier is saying that we should assume 100A unless proven otherwise.

What is the Reg No of the one that states Manufacturer’s info must be adhered to?

536.4.202

In the words of Elvis: No such number.

That’s in relation to a Consumer Unit, yes?
In relation to choice of OCPD yes?

It is in relation to OCPD protection for RCCBs. Makes no reference to consumer units or otherwise. If an RCCB is installed then it needs to meet this reg.

No, it doesn’t specify CUs, but it does make reference to the British Standard that applies to CUs and to the overall rating of the assembly, which suggests the assembly is ‘type tested’ and therefore a CU.

BS EN 61439 is the Standard for Low-Voltage Switchgear and Controlgear.

Anyhow, where are you going with this point?

It also includes a BSEN 60947-3 isolator which also requires overload protection

Just had a wholesaler email. Hager have responded to their interpretation of this by releasing dual RCD boards with 100A RCCBs.
