Whilst we would like to believe no one would turn on a MCB after hiring a electrician I have now seen it done 2x. Simple device perhaps a bit overpriced but it is very robust.

Easy to use an works well

Simple and effective, this is very easy to fit with a lock or simple cable tie. Either way it does the job well
