I have recently moved into a house, which is approx 10 years old. I am looking to replace the ceiling mounted bathroom fan, which currently operates from a pull cord in the bathroom. I have purchased a new ceiling mounted fan from B&Q (model number NDX100BC). The current connections into the fan are simply live and neutral and the connections in the pull down cord terminal are live, Neutral and earth. I am looking to extend the cable by approx 1 metre and channel it down the plasterboard to a surface mounted switch located outside the bathroom.
Can I use a simple junction box to connect the existing wires (live, neutral and earth - which are currently wired to the pull down cord terminal) and run a length of identical cable from the junction box to the back of a surface mounted switch?
The bathroom light is also connected to a ceiling pull down cord. Would it be possible to do the same thing and maybe channel both cables down the wall and connect them to a 2-gang switch with one switch operating the bathroom light and the other switch operating the bathroom fan?
It does recommend using a double pole-isolating switch. Any advice would be greatly appreciated.
