Well it quite possibly is feaseable either ring or radial. If you have adequate knowledge to do it safely you could trace the connections in order to establish the equivalent circuit on paper and make decisions accordingly but might be advisable to have an EICR (Periodic) inspection done by...

Well in my opinion, example, electric shower, the "safe zone" should be horizontal or vertical in alignment with the whole of tge width or height of that shower heater case it self. The ordinary person can not be expected to remove the cover to see where the actual conductors enter the back of...

I think that some regard safety devices such as fuses, MCBs and RCDs with high esteem if designed and installed in accordance with BS7671 and OK I am prepared to go along with that so long as we only view such safety as being relatively safe and not as absolutely intrinsically safe. There is...

If I am still around in 10 to 20 years time then I might be persuaded tgat AFDDs are a good idea. I, already, do think that surge protection devices might have their merits

True we always base OPD short circuit and earth fault protection to be with "bolted faults" (negliable impedance) where we know that real world we might well be faced with lightly touching rusty parts of higher impedance and this RCD action might actually be the device that is saving us from...

I dont disagree with you John, i am just quoting the three basic considerations we must cover by one means or another and these are the initial considerations we are taught 1 or 2 or all 3 of them might be covered by the same OPD or indeed by seperate devices or also by the nature of the load...

Is it robust and identifiable and will it remain so throughout its lifetime? (Trees grow!)

So long as 1/ Overload, 2/ Short circuit & 3/ Earth fault are dealt with in an appropriate manner for the cables as installed we might just decide on the most readily available/cheapest Over current protective device.

Well just because lots of people refer to it as PAT Testing does not make it tge correct term to use, does it? TUC Congress, PIN Number. Just two more of the many examples! In the electrical world we have Live, Ring Main and Spur used incorrectly amongst others.

PAT Testing ? Portable Appliance Testing Testing?

Well it could be. However you need to consider that a trip of that RCD for another reason will also trip out the garage (including lighting) and vice versa. How would that cause inconvenience/safety issues? Putting it on its own RCBO from the consumer unit or a standalone switchfuse is an...

I absolutely agree agree with what flameport has said. However twin sockets and single sockets are often same or similar price, in fact single sockets are sometimes more expensive than twin sockets (it is down to manufactures production runs and wholesale discounts). I would normally pretty...

Yes absolutely. A few years back I was doing multiple zone heating and HW for boiler heating systems via hardwiring stats and valves and the plumbing/heating bods were describing to me how each particular system was required to work, sometimes I would devise a little electronic circuit or ready...

Yes. I think why the old coding was dropped is because many had a mindset that the old codes 1 were viewed as immediate attention whereas 2 sooner or later which resulted in just the code 1s being important and the code 2s being left forever in practice, which was totally the wrong attitude. I...

Actually, whilst I was ok with Green for Earth I am more than happy for it to be Green/Yellow. It’s the Ls an N changes I am not too happy about
