My RCD won't reset after testing

[Peter Ermera]

my RCD's wont reset after testing.

I have 6 RCD in my fuse box all in a row (and only 4 MCB - which doesn't seem usual). After pressing the test button, the RCD triggers. The RCD won't however allow itself to be reset.

I have tried resetting with all the MCB turned off as well as all appliances + lights in the house, but still no good.

Any advice appreciated.

Hi - if it won’t reset after a successful test, try moving the switch paddle fully down, then up for the reset. Some types of RCBO trip to a mid position and require a “pull down” before they’ll reset.
