Hi All, Alternative methods include, insulation, the use of barriers or placing out of reach. Which do you suggest are used for radiators? Over these last few months a debate has ben taking place in order to find out why you all believe you can get away without earthing, it has now come...

You lot really can't cope with this can you? The EAWR tells you that all conductors other than circuit conductors must be connected to earth, Chapter 41 simply gives you a number of loop impedance values and tells you that if they cannot be met, you then also need to employ 'local'...

Hi All, Sorry it has taken so long to come back, I'm afraid that users of the IET forum are quite difficult to talk to. It would appear that a Mr. OMS, amoungst others, on the IET forum have mixed up the need for supplementary equipotential bonding with the need for "local" supplementary...

Bernard, Our concerns are limited to the consumers' side of the supply head, that is where are liabilities begin and end.

Shed, A 30amp ring main must be protected by a 30amp fuse carrier containing 20amp fuse wire. I didn't say 20amp fuse. Is this a bit too complicated for you?

Go on, explain yourself.

Oh Sheds, Is this an admission that the 17th Edition in reality lacks the terminology to explain itself?

Hi Guys, I don't think we can say that the Regs. have ever been wrong, some of the advice that has been given showed a bias towards changing from fuses to circuit breakers, but I wouldn't want to 'split hairs' over that. The basic advice has always been that small overloads of a long...

Hi All, We have four basic situations: Touching an energised circuit conductor. Touching an un-earthed conductor that has itself come into contact with an energised circuit conductor. Touching an earthed conductor whilst there is earth leakage current passing through the earthing system...

Hi Bernard, You seem to be worrying about 'Indirect contact', or the human body proving a second 'parallel' path to earth. I believe that earlier on in this thread I mentioned that the definition of 'indirect contact' had mistakenly been taken straight from the 15th Edition without being...

Hi All, Let's look at the past and EEBADS without the benefit of the RCD. Now nobody is claiming that EEBADS is fool proof without the invention of the RCD. For example in a circuit protected only by a fuse or circuit breaker, if your client (or you) should come into direct contact with a...

Hi Sheds, I don't wish to sound paranoid but the IET have a history of 'editing' what I have to say in order to make it un-readable, but I will give it some thought.

Whilst on the subject of doing what is reasonably practicable, I would just like to mention an idea that I have had regarding aluminium double glazing. If I am honest I will have to admit that I have been shying away from this topic for a while now, but I think that I may have come up with a...

Hi, Where you have so many conductors you certainly need to be careful! First you must assess what you believe will reasonably foreseeably present any added danger by potentially extending the duration of a shock under fault conditions; and then assess what can reasonably practicably be done...

Hi Bernard, Is it reasonable foreseeable?

Hi All, Using a 'fusing factor' is just common sense. Can you not see for yourselves that using a cable with a 36amp maximum current carrying capacity and 'protecting' it with an over-current protective device that doesn't begin to operate until the load reaches 46amps is potentially...

Hi Westie, Avoid household disruption? You are telling me that you believe it is perfectly safe to touch any energised circuit conductor because at these voltages either the RCD will trip or the current flow will be so small it will not be able to be detected, but when push comes to shove...

Hi Westie, I would be nice if your assumption was correct but unfortunately I know from experience that it isn't! There is a much less painful way to prove the point, get yourself a 'neon screwdriver'. If your assumption was true a neon screwdriver wouldn't be able to work, but we all know...

I'll tell you what Ricey, you summarize EEBADS for me and if I think its' any good I'll put it at the end of my Green book.

Keep your hair on Ricey, I'm still thinking about it.
