Juzzhome 0 Report post Posted July 29, 2017 It is important to instant the water heater as according to the specification of the manufacturer. The circuit has to be a direct line from the DB or Consumer Box, 20A double pole switch should be outside the bathroom and a junction 20A junction box in the bathroom. Install the instant water with a Flexible 2.5mm 50/0.25 cable and make sure it is earthed. For added safety, it is best to choose those model with a built-in RCCB or ELB and of course every house already has RCCB 30mA at the DB Box. This just an added protection in case the 30mA RCCB at the DB Box failed to work. Share this post Link to post Share on other sites
