Hello, I\\\'m just replacing the conglomeration of old fuseboxes etc in my garage/office with a new Wylex Consumer unit. Which circuits need to be wired into the MCB\\\'s? I have the following circuits:- Lights(6A); Ring Main(32A); One storage heater(16A); Underfloor heating(16A); To shed(16A); To Greenhouse(16A). Also how deep should I chase the wall for the cables for the underfloor heating? Thanks in advance.
