Life used to be simple ....

..........   if it doesn't salute you ...paint it !...if does salute you fit an RCD .  

Not any more .   Are we REALLY expected to start phoning manufacturers to find out what RCD  type to choose & fit ?  

can't imagine a Type A being very reliable.

What makes you think that Binky ?    Aren't they the ones we've been fitting for years ?  

Don't think I've ever seen type A, type B everywhere, occasional  S, or am I mixing up A and B and thinking of breakers?

So you have to ask your customer exactly what they are going to plug in.  Then give them instructions that every time they buy something new to check with you and see if you need to change their rcd for a different one?

Jog on.

And what happens when you need different "types" of RCD's for appliances when they are currently "sharing" the same RCD ? Recommend a new, bigger fuseboard 

The regs (or should I say the manufacturers) are getting out of control

it's just more speculative BS as far as I'm concerned. I hate articles like that, some people have  habit of thinking 'it's the law' and talking lettuced to customers...

oer ............ I fitted a replacement CU last week and forgot to offer AFDD's to the customer.................. whoops

OMG!!!!!     :redcard    "Hello  is that the Electric Police  ?   We have a bloke here .......... "

Happy to hold up my hands ..... in the hope JPEL / 64 members read it ...

Argh, you've all missed it, the future and there's loads of money in it,

imagine this, one point one rcd/mcb, we'll then have different coloured sockets a bit like in hospitals, but we'll have more colours, then manufacturers will supply equipment with coloured plugs on too. If it has a red plug it needs a type A rcd, which is indicated by a red socket, a type B by a blue socket, etc, etc.

Arriving on a call out to a tripping RCD, "it's ok madam, I don't need my test kit, I can see the problem straight away, some idiot has put a green plug into a blue socket" , don't laugh, it's the future, probably.

@binky, it seems like you’re a bit confused!

RCD’s are AC, A, B, B+, & F.

These relate to the leakage current they will detect, & which currents will cause them to malfunction, & I don’t mean nuisance tripping.

Think Robin D-Lock & how that works.

This is a real problem & it does exist now.

The magnitude of the issues depend on the connected equipment and the load & leakage it presents on the installation.

Any & all RCD’s upstream of a load must be compatible with said load.

RCD’s located in circuits which are in parallel should be unaffected, but all in series will be.

I was thinking like MCBs domestic RCDs are type B - my bad.
