[QUOTE="SPECIAL LOCATION, post: 557603, member: 250"] Electric showers generally have two heating elements inside the water chamber... (basically like a very small kettle with much higher power elements to heat a smaller amount of water). There is also a dial or some buttons to select either Cold (No elements on), Heat 1/Low (one element one), Heat 2/High (both elements on)... If one of the elements is damaged the live internal conductor of the element could allow electrical current to flow back via the water to earth.. If the shower is wired correctly via a 30ma RCD.. AND the RCD is working correctly it should trip the electrical supply off as soon as the leakage current via the water reaches somewhere between 16miliAmps & 30miliAmps... If the shower is not connected via an RCD and/or the RCD is faulty.. Then the shower could "appear" to be working via the one element whilst also allowing a possibly dangerous fault current via the second faulty element... Without some appropriate test meters it is pretty much impossible for a DIY person to accurately test/verify the circuit cables, RCD operation, Integrity of shower internal wiring/elements etc... Whereas a competent electrician should be able to verify all of the above during a standard 1hour minimum call-out charge.. Which if not living in or around London.. should not be too expensive! So as Andy said... Stop using it until you have had it properly checked over... Electricity can kill a healthy adult in less than a second... Which is why a competent electrician will never design or install any alteration just to make something work... They are always working to ensure ALL work will FAIL-SAFE.. i.e. disconnect the supply fast enough before anyone is injured or killed! Health & Safety Executive tend to enforce very strict rules if someone is killed due to negligent work!! [/QUOTE]
