RCD Breaker.x
Design is brilliant. Great value for the money. Functionality is excellent. Surge protection is brilliant because my tumble dryer every so often would trip out the power in my shed but it would effect all power even to my chest freezer. Has been well worth the money.

It has a light so you know when it’s working
This is an excellent RCD Mines in use every day as it protects cable going outside to my pond

Circuit protection and life saver
This has been a life saver, quite literally. Installed an outside socket, sealed the box but water still got I. Somehow and the RCD plug protected the circuit. I couldn’t work out why it had tripped until I took the outside socket apart and found water inside. The socket is going back but this is getting place of honour, back in the plug socket where the outside socket will be plugged in.

I'm still here aren't I?
Used for a hedge trimmer cord. Cut the cord, the breaker worked. Otherwise, I'd be well mad. Worth having for anything you are doing involving something on the end of an extension lead or not.
