Things That Go Bump…

And I’m not talking about spectres and headless horsemen that may roam around your premises at night…although these can seem harmless when compared to a little device called an RCD is non existant in your home.

I really believe that the RCD has been a groundbreaking invention in the electrical industry. Basically speaking an RCD is fitted to a consumer unit (fuse box) and if anything were to malfunction such as a kettle, washing machine or hairdryer then the RCD would activate (within less than a second) and cut the power to the appliance concerned.
