Two jobs I was at yesterday and neither of them had an RCD (safety switch) protecting the showers. RCD's are a safety switch that will protect lives if installed properly. They should be tested at least every two months to ensure correct operation.
I put one of the showers yesterday onto an RCD and the RCD tripped out indicating a very dangerous situation.
Please protect yourself and family by ensuring your shower and sockets are protected by an RCD. See previous post about testing RCD's. If you have any worries about testing the RCD's or any questions, give us a call on the phone and we will talk you through it.
