    Are these the same

    You should breeze 2382 (or 2383 as I think it will soon be), given that you have been looking up regs for weeks. Ask your college tutor about it as they might just let you do the exam which should be cheap.

    Electrical fault - who pays?

    100kwh/day = about 4kw all day. How big is your underfloor heating (or room with it in)? Mat could be say 200W/m so a 4.25mx4.25m mat (BIG) would use 3.6kw. Without knowing more about the setup its difficult to know if that is your scenario. So in principle it could be just the underfloor...

    17th edition amendments?

    In that case I take it back!

    17th edition amendments?

    Why not have an objective look rather than a knee jerk reaction. So for example you as a good honest spark will RCD protect an extension to a lighting circuit with a chased cable, because that's what the regs say and so you do the right thing to do. The cheap spark doesn't because he doesn't...

    Part P Qualification???

    There is City & Guilds 2393-10 – Certificate in the Building Regulations for Electrical Installations in Dwellings. Which I would say is a part p qualification in the same way that people with 2382 say they are "17th edition qualified" (after all 17th edition isn't a qualification its a revision...

    Test Instruments

    Better to get into the same terminology as early as possible then you don't have to forget and relearn later, you will get to 2391 at some point! Looks like your doing pretty well on most questions these days, keep it up and I'm sure it'll be fine :D

    How do scheme providers look upon PULLING THE MAIN DIST FUSE

    Err if you didn't ask them to remove the fuse you could hardly accuse them of unreasonably withholding permission! If you ask them and then pull it you are opening yourself up as you will have effectively said there was a seal and will therefore look dodgy if/when they turn up. If you didn't...

    Test Instruments

    GN3 says that you use an earth loop impedance meter on PFC range to measure both PFC and PSSC. I don't think you get marks in 2391 for PFC PSCC tester but I could be wrong on that. The answer will be in A or kA

    Determining the cas of the CPC

    Was there any more information in the question? What about for instance the current rating of the fuse? pg 247-248 will give you the time for the fuse to blow which would be required to use the adiabatic equation to get an optimal CSA

    Subject: Mountain Trail in Spain

    Walked along most of this about 15 years ago until it got to the bit with no concrete and just a steel beam with no hand wire (other places they had a cable bolted to the wall you could hold onto which was OK) Truly awesome in a scarey way! took ages to retreat back the way we came. Getting...

    bizarre news stories

    Did anyone see that Lady Gaga (yes her of the genuine raw meat dress fame) had thretened to sue ice cream shop describing the idea of the ice cream as "nausea inducing" and stealing part of her name (obviously nobody has ever used gaga in relation to a baby before)

    on line exams

    As I see it if someone asks for help then its reasonable to give it to them if they appear willing to learn. I have helped people previously and suggested that they provide answers / workings for their best guess at the answer. In general people seem to have gone along with that in their...

    on line exams

    Depends on several things, level of experience, quality of teaching, cost of course. Mine was 400 for 5 days at local college, my background was electronics rather than electrical as I have said in previous posts I think everyone on our course learned stuff and discussed stuff even experienced...

    on line exams

    You can't sit 17th edition online as it has to be at a C&G approved centre. Speak to local college they may let you do exam without course (although I guess it would have to tie in with their course dates) at a reduced cost. Some training providers may also let you do it, contact them direct...

    Regulation 314 Division of Installation

    If you changed a light switch would you pull out all the nice black and red wiring that was put in 10 years ago to replace it with the much more attractive and fashionable 2008 edition blue and brown? No However if you add a new switch then IT and ITS new wiring have to comply with the current...

    Regulation 314 Division of Installation

    Presumably it is RCD protected now and that may be why it became an issue. There is no requirement to make an old install comply to new regs when the CU is installed and so splitting the circuits is not really required, hence the question of new install versus change by telectrix, you shouldn't...

    Regulation 314 Division of Installation

    As sparky3366 observed if the upstairs and downstairs circuits had a borrowed neutral then it is possible that when the board was fitted the installer chosen to join the 2 together. In the borrowed neutral scenario if the 2 circuits been put on separate RCDs then the RCDs would have kept...
