These devices are the most important electrical safety device you can have. If you have an electrical shower you should definitely have one.
This year I have come across three instances in Monkstown, Dun Laoghaire and Cabinteely where people with electric showers did not have one of these devices.
I know of two instances where people have died because these devices were no installed on the shower circuit.
There should also be one of these devices on your electric showers.
If you have any questions, give us a call.
