Advice on fixing this outside mess

[oscar21]

You make a good point, I wondered that after I wrote it.

I had the same problem a few months ago, my mate was looking at some wiring in a food wagon and he rang me for advice on what to do next, he says there is a 32A RCD protecting the installation without any breakers and I said well if its a 32A RCD then it must be an RCBO so its covered but he was adamant it was just an RCD, when he sent me a picture and I looked a bit closer it dawned on me that it was indeed just an RCD.

If it said 63A or 80A etc the you would automatically assume its just an RCD without any other protection, its just the fact that it has a low value on it that I think loads of people will think its an MCB as well, same as the 20A and 25A ones that are also knocking about. Just doesn't make any sense to me to have all that different tooling to make different rated RCD's when a 100A would cover everything, the cost on saved metal must be minuscule.

So it isn't working because it has been disconnected?

That would be the case. Initial when looking the RCD was off and looking inside and seeing the water ingress I then done some testing and when nothing happened I then went to the Consumer Unit in the Garage.

I'm not sure why some people make this assumption, but it certainly calls their competence into question.

Would they make similar assumptions about the rating of an isolator?

Not the outcome I'd been expecting.

Just goes to show, start with the basics.

With that now the culprit. I’ve ordered a vent plug for the Wiska Box. Some Wago 222 Connectors and something to connect the Wiska Box and RCD enclosure.

In hindsight singles would probably be better but I’ve got 30m of NYY and the price of cable and also selling the NYY.

Why are you going to replace the cable?
Are you going to reconnect it?

I suppose everything has a price point. It could be quite a bit more expensive overall to manufacture a 100A rated RCD compared to a 25A

So the manufacturer only making 100 A RCDS would be competing on price against the 25 32 40 and 63 manufactured by others

Other than having been disconnected is there anything wrong with the existing cable?

I can’t reconnect it. It’s been cut between the garage and outside.
