What rating of Wago...

[JohnW2]

Having seen a 10.5kW shower circuit wired in 2.5 run quite happily for 2 years until the switch finally burnt out (could happen to even a correctly wired 6/ 10mm² circuit), I am inclined to think that cables, connectors etcetera have a lot of leeway engineered into them.

Indeed. As we've often discussed, I'm sure that there is an awful lot of 'leeway' built into cable CCCs we use. One could therefore probably 'get away with' exceeding the CCC of a cable by 100% or more without any problems. However, we don't (or at least shouldn't!) use that as an excuse for using a cable with too low a 'rated' CCC. Similarly with connectors ... as I wrote, I imagine that one could greatly exceed the 'rating' without any problems - but, again we shouldn't really do that.

Kind Regards, John

Must have been a crazy electricity bill! And water bill. And a very wrinkly owner.

Good video, but Why does he not isolate the circuit (switch it off) before poking it with a metal screw driver?!
