Important safety notice: Electric showers combine mains electricity and water and are potentially lethal if worked on incorrectly. This guide is educational and assumes appropriate electrical competence. Electrical supplies must be safely isolated, locked off where appropriate and proved dead before work begins. Live working is not instructed. Where the reader is not competent to carry out electrical work safely, a qualified electrician should be used.
