Suitable RCCB replacent

[gazdkw82]

I need to replace this old RCCB with a suitable replacement.

Currently the one installed is not tripping on test and from the test point. Changing the entire consumer unit is not financially viable for the home owner at present so I would like to change this to at least reinstate RCD protection.

Any help would be appreciated

Put up front rcd?
Try auction sites for replacement

That's why I'm looking at something that may be suitable in its place.

You need to fit the one the same back in its place

You need to fit the one in your link. That’s a decent price for one aswell, I’ve paid over £100 for them and the RCBOs before.

Nothing else will fit but a Sq D / Schneider of that type.
It's a unique fitting to the bus bars.

Just a note, Schneider changed all the part numbers for the old Sq D stock
QO200RCDX30 will be something else now as the replacement for the clip in type is a din rail type with an adapter.

is that faulty RCD an upfront device, doubling as a main switch? if so fit a stand alone RCD (any brand) In the tails fron the meter.

a secondary concern is that you might have a N-E fault.try testing with the outgoing cables removed.

Is it a Quickline I or Quikline II. Are the mcbs brown or white.

No its protecting only part of the installation. A split load board.

If there was a N-E fault then the rcd should do its job. If it's not tripping then the rccb is still faulty. There was a good Zs reading on the circuit and no odd voltages across N-E.

That's how I understand it...
