Product Information

In this case as 3-core cable is being used this will be the black wire to the permanent live (add some brown tape/sleeve to signify it as live), the grey wire to neutral (add some blue tape or sleeve), the brown to switched live and the earth to the earth (make sure earth sleeve is added first) as in the image below. It must also be possible to isolate the fan by means of a pull cord switch inside the bathroom, or a fan isolation (3-pole) switch outside of the bathroom. We have concentrated on the actual wiring in this section, rather than the other elements of the installation. Some people on this forum (who dont get paid for it, mind) have taken a lot of care to put together guides to help with the more commonly asked questions. Finally once everything is connected up, the last job is to turn the power back on and test the circuit to make sure all is well.

Finally, connect the pull-cord switch that wil be used to turn the fan on and off into the junction box using normal 2-core cabling as with any other light switch. As there are several different ways that a timed extractor fan is wired up, here we will cover the most common method; Taking a power feed from an existing bathroom light. In this guide we take a look at how a timed fan unit or extractor fan with a built in timer is wired up, read on to find out exactly how.Due to the colours of 3-core cable (brown, grey and black), certain conductors will need an appropriate blue or brown sleeve over them, to denote their use within the circuit (see diagrams below). Strip both ends of the cable to suitable lengths (manufacturer should state this in their instructions, if not see our stripping cable project here) and connect the switch end cable to the correct terminals.

If you are unable or don’t want the fan wired off of the lighting circuit and want independent control then an independent switch will need to be installed.Once this has been done your electrician will then issue you with a works certificate to state that all has been done to the required regulations. If it isn’t and there is no official evidence to prove it’s been done by a professional with the required qualifications then in the event of any issues it is likely that your home insurance won’t be valid and if you come to sell your home then this can again cause huge issues.

As we have mentioned above, you can take power from pretty much any location for an extractor fan, both lighting and socket circuits can be used once you have installed the FCU and the 3-pole switch. B. if you are in anyway unsure of how to carry out routine maintenance/cleaning on the fan, you should always seek the advice of a qualified electrician). The tiles are suitable for several types of ventilation, including natural ventilation, soil pipe ventilation and mechanical ventilation. If this is in a ground floor bathroom, you may need to pull up some floor boards to access and wire up. Again, if installing a axial fan through the wall you may need to chase out a section of wall to run the cable to the fan.

When it comes to electrical work in the bathroom, as this is regareded as a “special location” by the regulations, any electrical work can and should only be carried out by a Part P registered electrician so that it is ensured the circuit is installed correctly and to regulations standard, can be fully tested once complete and finally a minor works certificate can then be issued to sign everything off. There are several types of pipework but generally it’s best to use the PVC type as when using the aluminium round duct, the fan can echo through it when running creating quite a bit of noise, whereas the PVC type is generally silent. We can all take cheap shots in life, breezer et al, but your credibility will be judged on how you judge others.

The blase 'read the wiki' or 'god help us you're a moron' approach isn't condusive to encouraging people to post. Does it mean that I have two live feeds going into the light switch, one for the light and one for the fan? Also, for timed unit extractor fans, as there is an extra cable you can use 3 core and earth, however if wiring a standard fan with no timed switch, 2 core and earth is fine. The wiring diagram below shows the wiring setup you need to connect your new timed fan to your existing light circuit ceiling rose so that when the light is turned on, so is the fan. When wired to its own switch, the switch itself will either be located outside of the bathroom, normally above the door or it can be inside as long as it’s in the correct zone and is a pull cord switch.The instructions state that it can be operated by connecting it to a light switch so that the fan will start when the light is switched on.
