450mm to top of socket, but can keep same as was... so only new builds at 450mm????

Hey up mate.

Been reading through his thread, and found it quite interesting.

Are you just taking the exam? or are you doing the course as well?

There is no need to remember all the 7 sections and 16 appendices, as there is a list of them all on page 3 of the BGB.

I will give you a fairly rough idea of which part of the regs the questions will come from. The questions will usually follow the regs, so Q1 will be in Part 1 Q60 will be in the appx's.

You will get 2,3 or 4 Q's each from parts 1,2 and 3. 14 will come part 4, 15 from Part 5, and about 15 or so from the rest of the regs including the appx's.

The questions in each section are proportional to the size of the section. 4 and 5 are both huge.

Parts 6, 7 and the appx's are very easy to navigate around to find the answers, but 4 and 5 can be a nightmare and these 2 sections are where all the traps lie.

I find that most incorrect answers in the mock tests i use come from parts 4 and 5. Also the most referred to reg in the book is 415.1.1.

The incorrect answers are usually as a result of not reading the questions properly, or getting sent elsewhere to a table, getting the correct table and not reading it properly, and so getting the answer wrong.

Cheers..........Howard

Think of this heights thing as a "band" on the wall, 450mm up from the floor extending to 1200mm up the wall. Sockets and switches lie within not outside this band. So top of switches at 1200mm, bottom of sockets at 450mm. Or so I've always thought for the last few years...........................trying to find you a definitive link I just read Part M online and it says 400mm to 1200mm?????????????? Page 49. Or are they saying then that 400 to the bottom would put the centre of the socket at nominally 450mm?

Here's a link to all the Building Reg downloads:

As Malcolm was alluding to, that's Part M of the buiding regs i=p/u not BS7671.

aye was in the osg at 450 from bottom to top at 1200 , cheers malcolm. yes im doing the classes at 3 hours a week for ten weeks b ut only two weeks left then do a test, i know online and a choice of awnsers, i feel i will pass as you have 2 hours i think. i know what sections certain questions will be in, but ive only started looking at the regs recently so have to get to know what they saying anyway.... and your right sections 4 and 5 are longest, ps you forgot type your question

I found it helpful to put labled tabs at the start of each section so when looking something up in the appendix I was not spending too much time finding the right section. I bought reasonably robust ones from one of the large chains of office equipment suppliers, it might have been Staples. Don't put too many on though as it can take longer to work through them than to flick through the pages.

Q:- What IP rating should the top surface of a barrier or enclosure have?
Q: - What is the value of "Arms Reach"

 

[GLENNSPARK]

Page and part number where defenitions can be found and page and appendix number for ring and radial finals please I=P/U........

 

[i=p/u]

ok, i know it is IPx4 but dont know where to find
and i know its 2.5m and reg 417.3 which i founf using index

definataions is part 2 page 20, ring final circuits is appendix 15 page 362

I would have thought, it was 600mm, the same as zone 2 in a bathroom?

hmm spinlondon, you winding me up??

 

[Sparky Ninja]

When are you doing this exam?

 

[i=p/u]

28th november wilder , you can show me the 20 degree and how affects zs wilder if you wish if you chilling , it ok

It's in the OSG, Appendix 2. It states the corrected values are at an ambient temperature of 10 degrees C and Table 2E can be used to adjust for other ambient temperatures.
In this case, 20 degrees C would require multiplying the selected maximum measured value to be multiplied by a factor of 1.04

 

[i=p/u]

i thought multiply by 1.6 , as 20 degrees isnt in red book i guestimated 1.6 using the sequence..... so does this be done in the real world???? ive seen in some thread that you multiply by 1.2 is that figure normal used for safe side???


so much to consoder i bettter get 20 an hour when im finished this course lol
