My mistake, of course it must be a triple pole switch already installed, as it is a timer fan that is currently there.

Thanks for the reply. The DP wall switch is indeed installed in the bathroom, and was installed when the house was build 10 years ago by the builders, so I guess this was acceptable at the time. The DP switch and Transformer are installed about 1.5m away from the bath and at a height of...

I'm going to change my low voltage bathroom fan that has a timer, for a low voltage fan with pull cord. My bathroom is ventillated very well so I see no need for the timer function(To be honest its a pain). The current fan is powered on from the lighting circuit (comes on with light being...

I will use earth sleevng, I just hadn't put the green lines on top of the yellow ones. I assume its brown tape/sleeving used now since the change over of colours? thanks again for advice given!

I am trying to install 2 recessed mains downlights, using one switch and one junction box. I am using 1.5mm t&e cable, and 20A junction boxes. Are either of the following setups acceptable? Using ceiling roses or parallel connections to the light fittings will be pretty...

The 32MCB will not be on the RCD side of the house CU, only a 63 RCD at the shed CU. So my current setup is not acceptable? I still need a TT arrangement at my shed, or will I get away with leaving my setup as-is? Also my other point, does my shed RCD not require a working earth so I can...

From the advice gathered from this site, my final set up for my timber shed electrics is as follows. I will only be running low drain devices, but on the occasions of using mitre saws, heaters etc, these will only be used exclusively. PME house supply 32mcb in house CU -> 4mm t&e ->...

As in the picture, it states "Connect to common earth on customers installation only after insuring satisfactory cross bonding of services. Use 16mm2 earth cable" Below is a picture of the boxes immediately to the left of the first picture. thanks.

How to tell which type of supply my house has? It was installed 9 years ago(as house was newly built). I have looked at the "For reference" thread, but as the incoming supply to my house goes directly into a sealed box, how can I ell if it is TN-C-S or just TN-S? :? Many thanks for any...

Though the same can be said for a galvanised junction box, as I assume this would need the choc bloc as well. Would this then need fixing to the floor of the box as with the plastic j.box? I already have a long strip of 30A choc bloc, so thats not a problem. Or are these a better...

A simple and obvious suggestion, but one I certainly wouldn't have thought of! thanks for taking the time to give your advice.

First off, these are not my pictures, these are from the thread I linked to!!!! It is the reason I asked my original question! For the love of God?.......And this meaning........? That's the reason I asked that particular question. No-one appeared to be questioning benjiman's method of...

Just as shown on page 3 of this thread, //www.diynot.com/forums/viewtopic.php?t=27081. I am aware this is not too pretty, but it's the principle of the banjo connection to the earth block I'm interested in. Though on second thoughts, just using a bolt and nut as a clamp through the...

Hi, I was wondering why a galvanised metal junction box is preferred according to the advice on this board. Has the metal j. box any advantages over an IP55 plastic waterproof junction box, or could this just be used just the same? Also when in the junction box, could the banjo fitting...

Does Part P regulations apply the same in Scotland, as it does in the rest of the UK? I thought this only applied to England/Wales, and what if the job was finished last year :| ? I always make a point of searching through the forum before asking questions. Maybe I failed to see it, but I...

For the final connections I intend to get a sparky to finish the job, but I hope to do as much as I can to minimise costs. Could I use 4mm 3 core SWA as an equivalent to twin and earth, with me using the 3rd core as earth using the appropriate sleeving. Should this method be used in tandem...

With you quite rightly asking how I would test it, how would I test that earthing the shed consumer unit to the main consumer unit would be enough, or is it accepted that all wiring connected would be earthed properly as long as it is installed correctly to the main board? Again, thanks for...

So a standard straight earth connection from main to shed consumer units(via junction boxes) would suffice? Would you be aware why the use of an earth rod is advised? It was recommended as the shed was 15m away from house. thanks for your help

I would be grateful for some advice on the installation of electricity to my shed. I'm going to put 4mm or 6mm SWA cable underground with junction box either end, as the entire run from main consumer box to shed consumer box is approx. 20m. I'll be using a 30A MCB in the main consumer...
