Hi chaps, I wonder if anyone has come across this before.
Customer has two old wylex fuse boxes with rewireable fuse, one board is for lighting, socket outlets, cooker etc and the other is economy 7 for immersion heater and storage heaters.
Customer wants both boards replacing but the previous electrician has wired the immersion to a 2 way switch so the customer can switch the immersion heater onto the main board to boost the hot water.
There is a neutral coming back to each board so obviously there are going to be issues with RCD tripping as it's currently using a shared neutral.
Are there switches available that will allow the user to power the immersion from the economy 7 board but switch to boost when needed and do it safely?
Thanks in advance!
