It 100% is as the earth goes to a terminal on a brass lamp holder and its all interconnected via the head metal work to the body. I've tested it already.

The SWA terminates at a outdoor socket then from that goes to a weatherproof FCU then comes out in rubber flex (in conduit) as its a cast iron lamp post that was originally gas powered so there were no provisions for electrical cables

Hi We have an old converted cast iron lamp post in our garden that has a copper head on and a 230v bulb... this is all connected via an SWA cable from the house protected by a 30ma RCBO. Is this OK to be connected to the house earth supply (PME) or should it have a Earth rod ? thanks

Hi is there an acceptable and safe way to joint either 2x twin and earth cables it a twin and earth cable to a flex all would be inside plastic 50x50 trunking.. Thanks

Hi, in my new garage I have some 50x50 plastic trunking all around the perimeter inside at roof level and I plan to drop 20mm conduit down to each switch / socket... silly question but what is the best way to make sure a drilled hole in the trunking will line up with the conduit once it's...

Thanks for your reply.

The twin and earth would be under the upstairs floor for 1m before it reaches the outside wall. We live in a cottage and the routes are impossible to fit a 6mm armoured cable. I would not be able to bend it round corners etc

thanks for everyone's replies... so what is the best thing to do then if like in my case there is no physical way to get the armoured cable all the way to the consumer unit? I can only get it to within 1m then it would have to be T+E

Thanks for your reply, is the 50mm rule still the same if this is under floor boards like all other cables? I have lighting cables etc that run under the floor that are not protected via RCD

I have a new garage and had previously run cable to it ready for it to be connected later. I ran a 6mm T+E cable from the consumer unit (cant get armoured all the way to it) it then terminates in a wiska box on the wall outside and continues in 6mm 3 core armoured. I had planned to have no RCD...

No longer need post...

even solid core cables such as twin and earth?

im talking normal joints though.. not armoured resin type

Thanks for all your replies, some interesting points here. How do you joint say a 10mm cable to a 6mm cable? surely you cant crimp a 6mm cable in to a 10mm uninsulated crimp joint?

Thats my point... i dont see how your supposed to do it if you REALLY needed to and keep in safe and to regs.

This is only for info as its something ive wanted to know for a while. if you have a 10mm cable and you want to joint it (for example maintenance free) how would you do this? most connectors only go up to 6mm.. and to make it more fun, how would you join a 10mm to a 6mm if you ever needed...

Hi, We have a new house and the consumer unit was replaced recently along with some other small jobs. I have a few questions about the work done only because I have heard different things from people about what's right and wrong: 1. We have a 15 way metal RCBO consumer unit and the electrician...

Thanks for your replies, would a Helvar L36 A-T work? I have one of these. I just don't want the lamp to explode or something daft!

Hi I have a 36w PLS 2 pin bulb like the one here: https://www.allpondsolutions.co.uk/36w-pls-uv-bulb-lamp/ I need a replacement ballast for it that I can place in a DIY enclosure, I would prefer electronic but don't really mind either way. I have been searching a while but don't really know...

Hi at my dad's house he has an outdoor lantern type light on the wall next to the front door that is currently wired in twin and earth tacked all along the outside wall. I want to hide the cable and drilling through to inside seems best. If I drill through the back of the fitting in to the...
