What's the problem?

[cosmicwonder]

Hello,

The CUR6330a keeps tripping, even when no sockets are turned on. The issue is the "sockets" switch though - it's the "sockets" switch that trips the CUR6330a switch. A few weeks ago, I had this problem but I thought I had found the faulty socket and the problem was somewhat resolved (by not using that socket.) But two weeks later, the problem is back.

Any advice would be really appreciated

Best wishes

A 30ma RCD can trip for a number of reasons and it is easy to be misled over apparent causes which are in fact unrelated. In particular N-E faults anywhere on any circuit can result in very misleading conclusions over the cause, resulting in time and money being wasted on wild goose chasing. Beyond eliminating loads plugged in or otherwise in circuit there is a limit to what you can do without proper test equipment and the knowledge to use it.
Employ an experieced elrctrician to carry out insulation resistance tests etc. A good electrician should be able to pinpoint the cause quickly and go from there.

As OLDBOY says, you need an electrician with the ability to fault find, just thought I'd reiterate his point as he's totally correct.
