wiring a ceiling fan with light and two switches

It is acceptable to use 1.5mm too, anything larger is still safe but unnecessary and will prove more difficult to work with.Ĭable types required for the timer fan above are 2 core (twin) and earth. The Minimum cable size for fans like this is 1.0mm. However, using the method explained below, each stage of the installation can be easily followed and easily checked for errors or problems in the future with minimal risk of confusion. There are other ways to achieve this where the junction box connections are housed within the 3-pole isolation switch, but that is more complicated to explain and increases the chances of someting going wrong. Instead, we are going to install a new switch that will turn teh fan on and off. This wiring diagram shows an easy to follow configuration for a bathroom extractor fan fitted with a timer, that’s not going to be turned on by the existing light switch. A = Switched Live Connection Wiring an Extractor Fan With an Independent Switch (not turned on by the light switch)Īs with the option above for connecting to the existing light switch, before you start any wiring, make sure that the power is off to the circuit you are working on!!.

D = Earth Connection = To all units…This wire should be sleeved in a green/yellow earth sleeve.

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 ligh is turned on, so is the fan.ĭiagram showing wiring method for a timed fan Which ever one you are using, the wiring itself should be the same. The Isolation switch must be on a pull cord inside a bathroom or as in the diagram above, a switch on the outside. Isolation switch for use in bathrooms and special areas for isolating circuits Installing a Timed Fan Extractor It must also be possible to isolate the fan by means of a pull switch inside the bathroom, or a fan isolation (3 pole) switch outside of the bathroom.īefore attempting connecting up a timed fan or any other electrical connection, please ensure all circuits are off at the mains. Wiring an Extractor Fan With a Timed Switch That’s Turned on by an Existing Light SwitchĮxtractor Fans with an integral timer or timed switch need a 3 core and earth supply to allow the unit to run on after a light is switched off.
