Extractor Fan Switch.

I have just stumbled upon this. A fan isolator switch with integral fuse. Has anybody any experiences with these please. Any good?

    Regarding showers, there is always the neon light on the ceiling switch and on the shower casing. But I thought that we were discussing fans.


    In as much that the topic has 17 hours ago drifted to fans from the OP of extractor fan switch, on the subject of switching off for mechanical maintenance, is your proffered use of the neon acceptable?

    It all depends upon the type of mechanical maintenance Bod. What did you have in mind?

    I have been looking at in line duct fans that can be installed in lofts. They run quieter if loft installation is possible. I have installed many Manrose 4 inch (100mm) duct fans. They seem to be well made and reliable.  Recently I have seen adverts for Blauberg in line duct fans. I have bought a Turbo-E-100T for appraisal.  The blades turn very freely and the fan blades are large. I believe that the motors are German made. The cost is less than that of a Manrose fan of equal size. We shall see. Time will tell.  I have no connection with this company except as a customer.

    I have used the vortice 4" in-line fan for many years.  A superb fan.  They also do not require a 3 amp fuse.    I screw it down with a bit of loft insulation between it and the timber to help stop any sound tracking through the timbers.  I have had one in my en-suite for 12 years and is used multiple times a day for quite a long time as my kids stay in there for ever it seems.

    Yes I know Vortice. I have installed Vortice fans many years ago. I have not seen them advertised for some time/

    Just lamp changing and cleaning then......nothing electrical. I suppose that some shower cubical fans do have a lamp.

    Let's not even talk about looping at the switch. Now then, what do we have? Loop in and loop out to the next room; loop to shaver socket; 3C&E to fan; switch drop to light switch; supply to luminaire. That's 6 CPCs, which won't fit in the back-box terminal, and the neutrals so a couple of Wagos. You need a back-box the size of a bucket!


    Just stuff em in Chris.

    Interesting use of lever Wago connectors! I don't think that you are supposed to put 2 wires in one hole.

    I wasn't sure about that too Chris. Especially as the mention was made of using 1.5mm2 at the start of the video. If 1.0mm2 exists already will a Wago reliably hold the two sizes of wire?

    I have just tried it. 2 x 1.0 mm² conductors are held reasonably securely as are 3 x 1.0 mm². This is not surprising given that they may be used with stranded 2.5 mm² conductors (but only fine stranded 4.0 mm² ones). The problem is combining different sizes. With 1 x 1.5 mm² + 1 x 1.0 mm², the smaller conductor is not gripped at all.

    I thought the same, but actually you can use them to terminate the stranded conductors of  twin and earth cable and the like, so is there really any difference?
