With my C&G hat on I would say something like.....(A)Seek permission from owner to isolate installation. Once installation is safely isolated (safe isolation procedure), using a (B)low resistance ohmeter, (C)disconnect bonding conductor from earthing terminal and place one probe on to it. Then using a long lead (wander lead/R2 lead), either null it out first or subtract the resistance of the lead from the end result. Place one end of the lead on to the other end of the bonding conductor at the bonding clamp, and the other end to the other lead of your test instrument. Carry out the test and record the result. (D)After testing ensure to reconnect the bonding conductor to the the earthing terminal and re-energise the installation.

You can also mention the 0.05 Ohm maximum reading for this test-let the examiner know that you know your onions!

 

[Guest123]

Agreed.

Surprised thay didn't ask for that in the Q.

 

[Baal]

That's C & G for you!

The question about instrument used

Without being told what the type of answer city and guilds would be looking for, I would tend to be abrupt and just state exactly what was used

I was then taught that a listed answer was what they liked,eg stating type of instrument, callibrated, with approved leads,set to the scale ,nulled etc
A long winded reply with just about everything that you can think of

Thats why I believe oral exams are much better than written
Someone may know exactly what its all about, but they dont express themselves to suit
An exam where the examiner sits opposite and talks the exam would in my opinion be a far better assessment but unfortunately not acheivable

 

[Baal]

I have to disagree-this exam is supposed to prepare the student to produce comprehensive written reports that could quite feasibly end up as legal evidence in the case of an injury or damage to property.

I also have to disagree with that
Unless the candidate is an already experienced person,the majority who pass the exam have very little idea of completing a comprehensive report,possible even just filling in the forms correctly

My own experience is that the 2391 is a fine exam,even in comparison to other discipline city and guilds exams, and is a brilliant foundation for inspecting and testing,however it does not prepare a candidate for reports or form filling,experience and on the job use of the knowlege is what does so

 

[Baal]

"the majority who pass the exam have very little idea of completing a comprehensive report,possible even just filling in the forms correctly"

Exactly, so how would making the exam oral help in this respect?

The opinion of an oral exam being better, was to reflect my opinion with regards the candidates actual knowlege not being dependant on interpriting city and guilds questions,giving answers that were not comprehensive and at the same time, that candidate actually possessing good knowlege of his subject

As far as form filling go,the reply I gave that the written exam is not sufficient preperation and the form filling was experience dependant,it was in reply to this

[Baal]

I think I know where you're coming from but in these days of litigation, anyone involved in inspection, be it initial verification or periodic, has to be precise with terminology and the written word, even if just for '**** covering' reasons.

Making an exam oral to help those that have trouble with full written would only serve to dilute the qualification.

 

[antimatter]

I'm with Baal on this one,

With a written exam, there is no leeway, you either know it or you don't and C & G are hot on terminology too, so if you knew your beans, you'd pass and if you didn't, you'd fail.

As has already been suggested, EIC, PIR, MW reports could end up in a court of law, so if you passed on an oral test where the examiner "thought" it sounded like you knew what were on about, but weren't precise, you could end up in a lot of ****.

 

[Scotchydog]

Dont forget you could trip over the wandering lead and DIE! - Am C+G will look for that as well

 

[cooper]

Can anyone please help with the following question
what are the implications of of carrying out safe isolation procedure to
a) yourself
b)public
c)customer/clients
d) building systems
Thank you in advance

I have to take Des's side on this one. But Baal i do see where you are coming from to some degree. The 2391 0r 2394 and 2395 as it is now, wont give you the ability to write up a comprehensive report.It will give you the ability to use your common sense as an electrician to point out defects as their severity, and the general overall state of the installation you have tested, and also be able to recommend suitable course of actions to rectify any faults.

I look upon it as being a similar process as for having the car mot'd. you get a report, but not a comprehensive written one.

Expert witness type people compile comprehensive written reports, and undertake a lot of training to do so, i am currently doing the course. You have to remain open minded, and stick to facts not opinions, you must also justify all your findings, and so it goes on and on. EICR's are very much open to opinions.
