Ditch the surge protector. Lots of leakage current, and they don't give much protection.

Can one actually get passive ('latching') plug-in RCD adaptors? - like many/most RCD sockets, they always seem to be active
Kind Regards, John
It was a while back, At the time the shop sold both types. still have 1 on the van its a newlec, i will look up the model
It was a tesco bakery, the ring circuit tested ok, but one of the mixers etc seemed to trip the rcbo, we monitored a section of appliances at a time till the individual RCD tripped, cost about £100 for 3 but it found the fault
On a similar note, i was called out last week,
someones put rcd sockets on a rcbo circuit.
every night the butcher pressed the test button too turn the slicer off, this in turn tripped the Rcbo in the switchroom, resulting in 3 call outs before we sussed what was going on

I certainly posses some but I haven't bought (or used) a plug-in RCD in years so I don't know if they are still available.

A new 'panel' (consumer unit) will not fix this problem.
However
The proper procedure, when installing a new consumer unit, is to fully test all of the existing circuits. That should highlight any circuits that are out of spec and that may lead to a resolution.
You could, of course, find an electrician to carry out the necessary tests and produce an Electrical Installation Condition Report . This too should highlight any problems.[/l]
In conjunction with splitting circuits and the use of RCBOs it probably will.
It obviously would not 'fix' the problem - but, as some of us have said, it certainly should help in localising the problem, which hopefully could then be identified and 'fixed'.

1960'S RCD ? It's tired 
seriously. i had a mate who had a 1960's wylex board with a rcd main switch, it drove him mad until we tripped all the mcb's and went to the pub, came home an hour later and yes..... the rcd had tripped it was well due for the retirement home.

If you think that then the probable "fix" will be the OP getting rid of some of his PCs etc.
Because the problem is probably not one of something being faulty, it is probably one of the cumulative and inevitable leakage from the power supplies in all those devices. In which case splitting circuits and the use of RCBOs probably will fix the problem.
What the OP wrote was actually rather ambiguous - it may welkl have been a 1960s CU and a (younger, separate) RCD. I lived with such an arrangement for a good while in the distant past.1960'S RCD ? It's tired

IF that is the source of the problem, then you're right. However, that is speculation. I was obviously thinking more of the situation in which there was an intermittent fault, in which case the splitting/RCBOs would help in diagnosis, but would not afford a 'fix'.

Should we be suprised that neither of the so called electricians, when faced with a tripping RCD, did not carry out functionality tests on the device?
That sounds like a rhetorical questionShould we be suprised that neither of the so called electricians, when faced with a tripping RCD, did not carry out functionality tests on the device?
However, I wasn't aware that there was a second so-called electrician - I must have missed that somewhere.

Neutral-Earth fault........ Not saying swapping the RCD wouldn't have stopped the tripping, but all RCDs have a slightly different tripping point - hence the purpose of ramp tests.
They very rarely trip at 30mA
