Rcbo Vs Protected Circuit


Avotronics

Recommended Posts

Rcbo's take the same width as an mcb-but are usually longer and take up more room with the additional wiring directly attached to themselves, to fully load a CU with them is more challenging!.

I was thinking more on my own requirements, I can lose two rcds and two mcb and gain two rcbos. Must be better in terms of space, no?

But yes, I agree that if you are keeping current rcds then it may be worse.

True, but then you could do that anyway, could you not!

| isolator | non rcd mcb | rcbo | rcbo | rcd | mcb | etc

I do have a need for splitting circuits as its for my workshop and I've a lot of test equipment, etc.

But I agree with the cost factor, business seller on eBay has 40+ mk 16 way split load fully loaded con units and I could have won one today for £58. That had two rcds as well.

Have to bid I think.

Depends what its for I guess - if its for a house, and you have a freezer on one circuit and a N-E fault on another both fed from the same RCD, and you can't find the fault... :-(

So, I've decided to take my work back underground.... to stop it falling into the wrong hands
