It came to light recently that electrium (own wylex,crabtree,volex,etc,etc,) and MK are supplying cooker switches,shower pull switches,dp switches etc built to a bsen number that's unsuitable for isolation according to the big green book! I spent ages on the phone and emailing trying to get an answer for them to finally admit they advertise/sell isolators unsuitable for isolation so when we put a new shower circuit in we need to take into account the shower manufacturers instructions that ask for a double pole ISOLATOR and we've been fitting an unsuitable SWITCH! only Hager appear to be the correct bsen number!
