outside light

[Allan j]

Hi All new to this forum but it looks good , my question is i want to install an outside light i don't want the cable to be seen on the outside of the house it is a bungalow. so cable is going up from the ccu i was planning on going down the wall in the inside of the bedroom chasing the wall out and drilling to the outside and then plastering over the chasing in the bedroom is this ok my concern is that it will come down the bedroom wall passed the 150 safe zone it will be RCD protected can anyone advise

Many thanks

Thanks Very much for the welcome

You are not allowed to run outside the safe zone irrespective of RCD protection.

Also any external electrical work is notifiable so would either need to be carried out by a Part P registered contractor or you would have to pay LABC to pass it off ( if you have the competence to do the job yourself )

If you do then the easiest way would be to run the cable from the CU or an adjacent socket to an FCU then go outside. This way you have an outlet that indicates that a cable is run vertically/horizantally from it.

Plus gives you a mean of isolation for the light on its own

I beg to differ. Not ALL outside work is notifiable.

Refer to 'General Guidance' additional note i. On page 9 of Part P of the current Building Regulations:

http://www.planningportal.gov.uk/uploads/br/BR_PDF_ADP_2006.pdf

"The installation of equipment attached to the outside wall of a house (for example security lighting, air conditioning equipment and radon fans) is not notifiable provided that there are no exposed outdoor connections and the work does not involve the installation of a new circuit or the extension of a circuit in a kitchen or special location or associated with a special installation."

If it's an extension of a lighting circuit in a bedroom and the fitting is LV and not ELV and the cable goes directly through the wall to the fitting then the work does not need to be notified. It does of course need to be tested and certified.

chase down the wall to a maintenance isolator (or fused spur) for the light and then drill through the wall behind the isolator that way you are creating an obvious route for the cable ie vertically and or horizontally from an accesory mounted on the wall. then put a 3A fuse in the rcd fsu and a 5A fuse in the maintenance isolator create discrimination (think that is the word I am looking for).

I stand corrected, thanks for that smugley.

I always use the Elecsa Checklist for notifiable work and take outside lighting to be classed as Garden Lighting. Not any more!!!!

That'll be Elecsa trying to make a bit more money! ( or me being stupid! )
