Which earth leakage clamp meter and RCD tester to buy?

[88v8]

30mA RCD tripped out twice now, about ten days apart.
One RCD runs everything.

So I can start chasing it, I believe I need an RCD tester, and an earth leakage clamp meter.

Any recommendations please? Don't want to buy some cheapos that are too inaccurate to do any good.

They also need to come with good instructions as I can see from past threads that this is not necessarily straightforward !

Thankyou.

Re the tester, you won't go wrong sticking to the major makes - Fluke, Megger, Martindale...
