Rcd? Rccb? Rcbo?

[piggyitm]

As far as I am lead to believe, an RCCB has overcurrent protection.They look just like RCDs tho as there is no Type B or C rating on them?I've recently installed one and i'm now worrying if its right.Any help?
Cheers

RCCB = Residual Current Circuit Breaker. Nowadays known as a Residual Current Device (RCD). NO OVERCURRENT PROTECTION, which is why there's no B, C or D.

Don't confuse them with RCBOs = Residual Current Breaker with Overload. Combined MCB and RCD, though the single-width ones only disconnect one pole, like an MCB. These DO have type Bs Cs and Ds.

Don't worry, failure is simply the opportunity to begin again, this time more intelligently...lol

Pity I can’t send or receive PM’s at the moment E54. got a good tale to tell you. I’m going to hijack a mates PC later this week and see if I can sort out the mess I’ve created on this B***y F***ing pile of C**p of mine by attacking through another door!

Incorrectly understanding protective devices is a little bit more serious though. Especially leaving a circuit in service with no overcurrent protection.

Agreed, and I’m sure he will sort out his indiscretion and not make the same mistake again.

I await with interest then Tony....

There's always the 60a Service Fuse to fall back on

Luckily it only feeds a 2 way board with a 6 and 32 and its a 10m or so 10mm t & e feed!
