I came across an electric shower again today that was not protected by an RCD/RCBO/ELCB. If your shower is not protected by this safety switch you are putting your life and the lives of your loved ones in danger.
If you are not sure, call us and we can advise you over the phone at no charge to you. Photo shows a typical Earth Leakage Circuit Breaker (ELCB). Note Test button on bottom right corner. The Test Button should be pressed once every three months to ensure the ELCB (RCD/RCBO) is operating.
