I've been reading and re reading this.. and the Guidance note 8 post a couple of weeks ago I posted, and the touch voltage post I posted as well. I'm still confused.:( Re the above. I have used you figures, but don't you need Ze as well, to get the fault current, to work out the volt drops...

No need to apologise John. I really appreciate your help.

Thanks for your help with this John. I really do struggle with simple algebra, so following your excellent posts does take me some time. After reading my following post, you will probably want to start banging your head against the computer screen. I completely understand if you want to bail...

Thanks so much for your time and effort on this. I am struggling a bit with Rx . I do feel the mist is clearing, but every-time I think I get a break through, another question arrises.o_O I hope to have some sensible input shortly.

Thank you John, Im going to have a good read through this.

The picture from the book is showing the earth fault loop path. The Zs is 1.29Ω The Ze being 0.69Ω. There is an earth fault on a resistive load (5kW) Which is sending a fault current down the CPC (0.30Ω) and down the means of earthing (0.25Ω) The figures next to the photo are the equations from...

Guidance note 8 - Section 5 Protective equipotential bonding Im getting a bit lost here..... I have attached an image from the book, and my own version of the same image.... This section is about touch voltage and how that changes, if you add Protective equipotential bonding. The basic premise...

As mentioned Varilight V pro. The best domestic dimmers on the market. But you also need good quality dimmable lamps

You need to confirm if it is an extraneous conductive part. (Not part of the electrical installation but can introduce a potential) Is it possible to come into contact with exposed conductive parts (Such things as metal light switches) whilst on the steps?

These fans constantly cause problems, due to the over engineered mechanisms. It always jams up eventually. Fluff and dust can be cleaned out, but eventually you will get fed up and replace them. Sometimes the cover is not quite on right, and that can affect the mechanism.

V-pro do a 300w version which should sort you out. https://www.tlc-direct.co.uk/Products/VLMJP300.html

Its a made up report. The results are to perfect. As for the observations Item 1 - Incorrect. Item 2 - OK. That would need to be replaced Item 3 - Most pendants have live parts accessible without a tool so incorrect. Item 3 - Zs test results all look OK, but one is missing.

Just your standard lamps, that you plug into the sockets. These give good light, and you can't see the light source. So easy on the eye, you get a nice level of ambient light, with no expense, apart from the lamp it self. And if you need more directional light, buy a lamp that suits that need...

I would suggest you try to find an easy going electrician, who would not mind having a free labourer on site. I hope you have quite some holidays to come... The electrician would give you very defined jobs, to the specification you have agreed on, designed by them. He would then come back and...

A good read John. The governments around the world really are in a very difficult situation. Being naturally cautious, I would prefer tight control. But it seems that all we do by lock downs is just postpone the next wave. Made good sense while the vaccine was developed. Completely dropping all...

Just wondering how an insulation resistance tester actually works? I know how to carry out the test, but just wondering how does the meter calculates the values. Thanks

Some silly errors, and some incorrect coding, but nothing scary in the test results Buy the house, if you love it... Don't worry about this certificate, the person who filled it in didn't. When you move in get a decent Electrician to give it a once over, Im sure you will be making changes, so...

Yes The fitting itself is IP 65 ALLLED is a London based manufacturer, not sure how wide spread their distribution is, even online their presence appears quite small, and a quick look seems the online prices are over the top The trimless bezel is around £7 but online Ive just seen it for...
