I have a customer who has an existing electric shower fed by 10mm t&e, cable is buired in wall(plasterboard) fitted when house was built approx 13 years ago. They now want another electric shower fitted to the ensuite but does not want the house torn apart to run a new cable and doesnt want surface trunking. They asked if I can connect the second shower to the original circuit but load would be to high so can any one suggest an isolator/switch that can be fitted tp allow only one shower to be used at any one time.
Thanks
