Outside light and timer, switch required?

Former Community Member

Hi, I have to install an led outside light and a timer will be installed indoor to control.

The timer will get a feed from a room light switch.

The light wont have a pir just timer controlled.

Would it be normal practice to have a 1 pole or 2 pole (for neutral isolation) after the timer to isolate outside light for any safety purposes, or is this overkill and unnecessary? 

Also timers normally have an override so won't need a separate switch for that purpose either.

 

Any thoughts would be much appreciated. Thank you

    Regs do not insist on another switch, as you can switch off at the fuse board if required, but if it is fed from a circuit supplying some or all of the rest of the building,  then if say water gets in, the whole lot could go off and stay off, which could be awkward. 

     

    There is a lot to be said for the convenience of being able to isolate in such a case, but it is not a requirement.

    I presume the timer can be set to an always off state, but that may or may not be desirable.

    I presume you have already checked that there is a neutral at the existing light switch you intend to tap into - as quite often there are only 2 wires, a steady live and a switched live to the light fitting, neutral only being needed at the light fitting.
