2391-10 Written Exam - 01/12/11

[cr0ft]

Just sat this tonight. What does everyone that sat it tonight think of the paper?

 

[pfjt]

I'm not sure how I did q1 and 4 not sure wot I should have put aswell as the live working question. Can u remember q1

 

[cr0ft]

I was unsure about a few of those ones, again more due to it not being very clear what they were asking for.

I think the live working question was something like what considerations must be taken prior to working on or near a live appliance. I put: -

1.) Is the live working really necessary?
2.) Can the equipment/conductor be safely isolated?
3.) Are tools etc insulated to a level suitable for the voltages present.

Can't remember questions 1 to be honest!

Just remember that all 3 of those questions, even if you got them completely wrong are only worth 9 marks. As long as you did ok in section B you are most of the way there already. That's how I see it.

 

[pfjt]

Fair point. And yes the way they ask the questions is like a riddle sometimes

 

[pfjt]

Does any body remember q1 and q4

 

[pfjt]

Q21 when it asked fee the documentation for the completed electrical work did it jus want the elec certificate and schedules and not the periodic aswell

 

[Former Sponsor TM]

On Q21 for new electrical installation work I put an Electrical Installation Certificate accompanied with a Schedule of Test Results and a Schedule of Inspections, for the Inspection I put a Periodic Inspection Report for an Electrical Installation, again accompanied with a Schedule of Test Results and a Schedule of Inspections. It carried 6 marks so hopefully thats a mark for each one....

Q1 I think was the list on page 17 of GN 3?

Q4 was something along the lines of why do we do an initial verification:-
1, Confirm installation/circuit complies with designer's intentions
2, Designed, Installed and Inspected & Tested to comply with BS7671
3, Not damaged so as to impair safety
Just seen it in some notes, not sure where it came from though as nothing in GN3.

Don't you have to add a x1.2 correction factor to the volt drop formula to allow for the rise in temp when the circuit is under load?

Good luck to everyboby, only a couple of months to wait.

Just sat this tonight. What does everyone that sat it tonight think of the paper?

I like others not too bad but questions 1 and 4 were confusing, I answered Q1 then when i got to Q4 thought isnt that the same as Q1. I answered for Q1 to ensure installation meets relevant stds, e.g bs7671, to ensure nothing in the installation is damaged and to ensure all equip is erected correctly.
for Q4 I answered to protect persons, livestock and property. My worry is that Ive got answers wrong way around.

What was the special location that cant be connected to a TN-C-S system??

I put caravan park

 

[exnavysparks]

I put down caravan site for that one i think?

 

[exnavysparks]

what did ppl put down for the supplementary bonding Q i put agricultural location eventually after a lot of scribbling out and correcting lol

 

[pfjt]

I put bathroom for bonding. And mobile units for the tncs

 

[SHOCKNOT]

Dont know, I put both lots of documentation down but making sure that i said for the initial verification you require a EIC, SOI AND SOR, then for the PIR you need PIR, SOI AND SOR, however the SOI is shared between both (it covers both)

 

[SHOCKNOT]

I put caravans, some caravan parks are connected to tncs but you cannot connect caravans to a tncs arrangement so at some point you convert to tt.
