Installing Loft Light

[cwvxr]

I want to install a loft light. I was up at the weekend scoping the job out.

I currently have a junction box in the loft that the previous occupant had installed. This appears to tap into the existing circuit (landing light). This JB then has a feed to a switched FCU which controls the outside floodlight (on a sensor).

This is what I propose to do:-

Tap into this JB and take a new feed (1mm T&E) to a new pendant rose. Then from the pendant rose to the new switch. ‘I’m thinking of doing it this way as then I have a switched live to my new light rather than taking a feed to the switch and connecting the neutrals together at the switch then to the pendant.

Would this be a correct method of doing this?

Could I use a pull cord switch?

You need to ensure that it is the lighting circuit that the jb is on. If there is an FCU from it to feed the outside light then it may be a "socket" circuit and the mcb will not protect the 1mm twin and earth.

Its not notifiable so why would anyone bring it up?

Yeh cheers, will do

If I decide to go with the switch rather than pull cord, can i just choc the earth wire as its a plastic switch box?

 

[wingcoax]

Either that or get a plastic box with a terminal

I am going to do a BAS (RIP).

Building Regulations Part P applies to ALL electrical work in domestic premises.
The issue is that, for this works, you are notrequired to notify the work to the Local Authority.

wait... why RIP? has something nasty happened to BAS?

say it isn't so.. who will we argue with about the interpretation of Part P and specific regs now?

And mentioning it in a thread where the person has no obligation under part p to notify serves what purpose other than to serve your do gooder mentalitys. Most of the peoples post counts on this forum seem to be from spamming part p regardless of whats being discussed.

 

[ColJack]

you still have to comply with part P regardless of whether you have to notify the LABC.. it's not just a list of what you have to or don't have to notify..

in it's basic form it states...

P1 Reasonable provision shall be made in the design and installation of electrical installations in order to protect persons operating, maintaining or altering the installations from fire or injury.

Where does it state you need to post about it in every thread i must have missed that. Half the information on this site would be a damn site easier to find if people stopped throwing part p around for every other damn thread

I'm not sure if he's still around. He had a difference of opinion with BIG MODERATOR over some asterisks. He's been horribly quiet since then.

But every DIYer who dabbles with electrics needs to be aware of it, and they clearly arent. I'm a DIY'er who dabbles with my electrics when and how i feel fit. If i start a topic and someone yells part p at me I wont be taking offence.
