I tabbed my regs book for my exam today

[Rather be Fishing]

But one has fallen out. I saw it in my Van this morning just sitting there on the floor. I'm at work all day and then I'll be going tonsit it so I'm not gonna have a chance to go through the regs book to 're assign this bloody tab

If i show you the tab I don't suppose anyone would no what page it's supposed to be stuck to do they.

Go on then show the tab?

I've got a feeling it was for rcd trip times but I could be wrong.

Page 60 onwards refers to the earth fault loop and RCDs for fault protection.

Tabs are a waste of time in my opinion, tabbed mine for the 17th, got bogged down so I used the contents page got on better than with Tabs, all the very best what ever method you decide to use.

When I did 17th you couldn't use your own book or have tabs, that was at NAPIT.
As Pete, I wouldn't have had tabs, the index is better.

The last exam I took I was only allowed a slide rule. ?

 

[westward10]

Never used tabs, couldn't believe when I did the 18th the amount of tabs people had it was like confetti. I can understand a trainee using them but not a seasoned electrician.

And do the questions still run in Regs book order and do they still tell you on the pre-training how many in each section?

Hi,
You have probably wanted that tab to go on page 64 of the regs book, which is the Zs values for RCD's. I know my learners are not too keen on calculations, but if you understand how those values were derived then you would not need the table or the tab. Transposing the formula on the same page from 411.5.3 divide 50 by the operating current in amps for the RCD or the RCD part of an RCBO and you will have the Zs value in that table.
Example1 50/30mA= 50/0.03=1667 ohms
Example2 50/100mA=50/.1 = 500 ohms
God luck with the exam

I personally would only tab things that you can't find in the index or contents pages. Otherwise, as someone said above, your book will have nearly as many tabs as pages.

Thank you @westward10 and @jc_150 for your help there and cheers to everyone else for getting involved. I have to admit you've all been very helpfull I'm on the trainee forum but this forum is much better for a quick answer so cheers guys for being so helpfull towards me.

Ps. Just for entertainment purposes I'll get a pic of my tabbed bs7671, gn3 and osg. I haven't gone crazy but there is a few in each.

So glad it's open book I'm surprised it wasn't back in the day because surely if your out on site and have only recently just acquired your 2391 you not gonna sit there and guess your gonna whip out your books just to confirm or check some thing.

After a year or 2 I expect I'll have memorized every thing to the T but I'll would still have no shame in pulling out my books although I can understand how this may make you look incompetent to a client/collegue but I'd rather be safe then sorry at the end of the day

Don't worry about it, you'll never remember everything in the regs. But you will learn the key points, and have the ability to find the things you need. Especially when something unusual crops up.

I guarantee nobody has memorized the section on access gangways! Well, maybe Westy has ?

Yes, there are so many questions per section, if I recall you get told how many to expect, and the sections are in regs book order.
