It depends. If there's a vulnerable customer on a ventilator and dialysis with a lash up of outdoor ponds and garden lights, then it's very different to a top floor bedsit with two circuits and would most likely be coded differently. You have to assess each property on a case by case basis.

It depends. If it just happened to be a lockable room then of course that would be unsafe. If however it was a room designed for the purpose, and access to the key was restricted to competent persons, then perhaps less so. You or I may want to have (or do have!) a home workshop with limited...

Possibly yes, but it depends on the specific property.

I don't think it would be a good idea in a domestic dwelling, but in a commercial property, I'm not really sure to be honest. We have cabinets where I work which you could climb inside if you really felt that way out which contain unshrouded 3 phase busbars and can be accessed with a single key...

Yes that is the case, but they are different issues and would receive different codes.

Like in a substation? Lots of open live LV connections in a room accessed with a key. (lets not get into an ESQCR vs BS7671 debate!)

I'm assuming you mean RCD rather than DVD! But yes you are quite right. ALL domestic sockets ≤32A must have 30mA RCD protection. It is not possible to use the risk assessment get out for a domestic dwelling.

It's not just the being plunged in to darkness, but also not being able to reset any of the installation until the fault has been tracked and cleared, so no light, heat, cooking, freezer, access to DIYnot etc. if a single circuit, or even half of a dual RCD board is lost then most people will be...

The element in the shower has a fixed resistance so as the voltage to the shower increases so does the power consumed. Each house along your street will have a slightly different supply voltage, so the same shower unit will use a different amount of power (kW) in each house. Unfortunately this...

You do often say this, and I often say that I don't think there is over interpretation. I would be surprised to find anyone carrying out EICRs who didn't code a single up front RCD. C2 for lighting circuits serving a location containing a bath or shower if supplementary bonding is not present...

8.7-9.5kW depending on the exact voltage in your house. How is the cable run all the way from the fuse box to the shower? Is it clipped on the wall surface, plastered into the wall, in trunking, does it at any point pass through any loft insulation or other insulating material?

As you only have a 100mA RCD then straight away your installation will be found to be in an unsatisfactory condition. The height of the CU shouldn’t really be an issue as the inspector can access it to carry out his work. I have never heard of the step back rule mentioned above. It is most...

Great news everyone. Cooke and Lewis have spotted their typographical error and have corrected it, so we can all go back to following manufacturers instructions now. https://www.buddsbarns.co.uk/images/Cooke_and_Lewis_Oven_Manual-compressed.pdf

I live 18 miles from the Emley Moor transmitter and can’t receive a signal from it at all!

Because you can’t?

Hang on are we allowed to ask for proof? Last time I asked you for some proof you refused and called me a bully.

Yes I did and I saw that you failed to provide any example of a manufacturers instructions being incorrect apart from the only example ever seen of this situation, your b&q cooker instructions.

Do you accept that this was incorrect?

You made this up:

Please provide any other example of a manufacturers instructions being incorrect. If it is a frequent occurrence as you say it is, I’m sure this will be a simple task for you.
