Earthing arrangements query....Most common systems in UK:TN S;TN C S;Regardless of the system in all domestic?
The difference isZe or Zs values.The regs don’t allow use TNCS sys.in detached garage.Supply should be converted into TT.WHY?
IF U use drill in garage-fed from internal socket(RCD protected)through ext.lead - than this is OK. So why I have to create TT system in garage?
What if I have TNCS and want external socket, if is RCD protected–that comply? - Or I am not allowed to have it-Unless its part of TT system?
Imagine TNS system with damaged earth connection.U request upgrade of the earthing arrangements and They connect new earthing conductor into N is it? In all those systems the N is connected to E anyway
What if I will have high Ze value in TNS and connect my Main Earthing conductor to N at the service head–the Ze value should be lower?I think - in almost all cases when new supply is connected in London they provide PME supply regardless that your next door neighbor may have TNS system which is connected into the same underground supply conductor…..
What do you think?

Your garage is outside the "normal equipotential zone" therefor if you are supplying power to is as a separate fixed circuit then to guarantee an effective earth you should supply a means of earthing normally an earth rod(TT)You do not have access to the suppliers neutral terminal to connect your own earth to .If you have a socket that is protected by an rcd then it can be used outside no problem the rcd doesn't even have to be on that socket only it could be the main breaker

Zs is EFLI measured at the accessory.
It's the supply company who do not permit you to export their earth. Nothing to do with wiring regulations. http://www2.theiet.org/Publish/WireRegs/...
Using an extension lead to supply a tool outdoors is not an installation by the very nature of it's temporary duration. Therefore also exempt from BS7671.
BS 7671 permits external sockets where RCD protected. On the house wall is still considered to be 'within the equipotential zone'
And while it's also up to the supplier to determine what earthing system you are give; the advantage of TNCS over TNS is that an earth doesn't have to be 'sweated' onto the lead sheath thus removing its (sweating) associated health and safety risks.
And you are breaking the law if you touch anything (Cut-out) owned by the supplier . It is THEIR property, not yours.
Reply:TT every time, that way you know there is a path to earth. It's not my profession so I am just expressing an opinion, but I always grew up working on the principle the shortest route to earth must be through a direct connection and not anything that goes via me or has any likelihood of doing so.
Top question though because I have never quite understood why PME is the preferred option nor why you would even want to rely on a armour sheath TNS to carry your earth back to the transformer via the neutral, which is live as soon as a phase is connected to it. It all gets to be a complex balancing exercise which is easily resolved by connecting the consumer end directly to earth as well.
I always guessed it was a cost cutting exercise to avoid additional cable runs for earth and saved the hassle of driving rods into gas mains etc. in towns
My system is generator and solar but I still have copper rods firmly driven in at all the connecting points.
I look forward to other answers.

Just make sure that the box marked 'c' drive is checked.
Reply:go-to start....all programs...accesories....system tools then system restore..... if you go-to restore my system to an earlier time and have a look at the bold dates in the calendar these are the dates that you can go back to...if its a problem because of something installed it should be listed on the right as you go through the days....if you restore and everything is successful don't forget to switch off system restore by right clicking my computer and then properties and taking the tick out of the box....then switching it back on again by putting the tick back in the box as you don't want to have the same problem again.... good luck

Why is the grading system A,B,C,D,and F? Where is the E?
In many countries including the United States, grades are given on an A-F system where A is best and F is worst. Some schools have E as the lowest grade, rather than F. The letter E is typically omitted, since an F can be turned into an E by drawing a small line at the bottom of the letter, and because E traditionally stood for Excellent but would be very poor on an A-F system. A few US institutions do use the letter E for "conditional failure," which automatically becomes an F unless the instructor takes specific action in the next semester. In practice, even at institutions whose grading systems have this grade, it is very rarely used. An F grade is failing and results in denial of course credit, while a D is poor, but passing.
Why is the grading system A,B,C,D,and F? Where is the E?
What DonChuy says is true.... That's why.
Reply:Midwestern and northeastern states have tended to favor "E" since World War II while western and southern states still tend to use "F." Ultimately, the grade "F" traces to the days of two-point grading as "Pass" (P) and "Fail" (F). "E" is less common.
About that "E" grade -- some schools have used the E instead of F, but we speculate too many students tried to convince their parents the "E" stood for "excellent." It's much harder to trick parents into believing an "F" stands for "fantastic."
Reply:say wa
Reply:If there was an E it would be for EXCELLENT !!!!
DUH!!!!!
Reply:I guess those who came up with the system must have gotten an F in kindergarten.

Project to implement banking system in visual c++?
You need to be a bit more specific in your question.
Where did the grading system "A, B, C, D, F" come from?
Why is "E" skipped?
Do the letters stand for anything?
Where did the grading system "A, B, C, D, F" come from?
In some places, the letter 'E' is used as the failing grade. 'F' is used interchangeably because it is the first letter in the word 'Fail'.
Reply:It used to be E, but people decided F was better because "fail" starts with F.
Reply:A-awesome
B-boring
C-careless
D-dreadful
F-FAIL!!!
hope this helps.
Reply:When the system started there were all the letters from A-F including E. So after graduation, all the A, B, C, and D kids went on to live productive lives. And the F kids went to live in stupid homes. But then there were these E kids. They weren't smart enought to live productive lives, but they weren't dumb enough to live in the stupid homes, so they died. Thats why there is no E in the grading system.

Why is the grading system A,B,C,D, and F? What happened to E?
Well...actually, it's because when everything used to be hand-written, it was too easy to change and F into an E.
Why is the grading system A,B,C,D, and F? What happened to E?
too many kids were getting excited about recieving an "excellent" on their homework.
Reply:F is for Failure....and sound worse than E
Reply:They use E in Elementary school, it's the equivalent of an A (atleast in Florida)
Reply:I've always wondered that. But then, i figured that they use E for excellent in conduct, so that's why they don't use it in the grading system.
Reply:...for the same reason there are no "B" batterers....

Can we boot the system without active c drive ?
If your operating system is on another drive, then you can change the boot drive in the BIOS to that drive. If you're asking if you can boot into your operating system that is located on your C drive without the C drive being active, then no, you can't.
Can we boot the system without active c drive ?
You can boot the system with a bootable CD-ROM called knoppix
http://www.knoppix.net/
You can also use a BartPE CD which that can contain many useful utilities that can recover you from a system failure.
http://www.nu2.nu/pebuilder/
Reply:yes.. you should have the image of the OS in your HDD.. and then you shoud boot using the FDD
Reply:no u cannot boot ur system without active c drive, by default it is active, u have to make it as a active patition, then it will boot.
Reply:it depends on the operating system that u are using.
if windows 98, yes u can.
in windows xp u can use bootable cd for reparing or reinstalling..
or from pen drives that contain bootable system files
Reply:Yes you can , a system can be booted in anyways you want , but you need to have advanced knowledge of pcs .
The only thing that makes your system boot is windows , and the default installtion of windows occurs in drive c on most pc's
You can change the installation disk for windows and put it on other drive and boot the system
You can also boot the system from your network or from a disk .. try hitting f2 and go into your bios to see the boot options
Reply:.
For that you should use the boot floppy. Using a boot floppy you could access the hard disk and its data.

How do you tell what earthing system (TT, TN-C, TN-S, TN-C-S) a domestic electricity supply has?
Usually by inspection of the service head.
sometimes there's even a label from the supplier.
You can also enquire of your supplier.

you can contact your supplyer and ask, as if you dont know what your looking for its the easy way
Reply:As the others have said, there may be a lable on the incoming supply fuse box.
If there isn't a label then don't guess. It may even be different for your neighbour. You could be horribly wrong Call your electricity suppler.
Reply:The report you were given in the other question you asked says it TNCS if you doubt the inspectors competance then you should ask him to clarify, his name will be on the certificate and he will be happy to explain, I know I would be.
Reply:unless you live in the country its probably TNC-S.

Disadvantages of double entry system of A/C? everywer only merits of Double entry system are mentioned.?
Disadvantages:
Can be difficult to learn.
Requires multiple entries for the same transaction.
More prone to mistakes.
Finding mistakes can take longer.
Compare to single-entry or pegboard accounting systems for reference. Single-entry is faster to learn, but offers less flexibility and generally requires a smaller Chart of Accounts.
Basically, you are looking at a difference between using Quicken and Quickbooks (single-entry vs. double-entry).
Good luck!

Mostly operating system develop in c,why ?
The C programming language is considered to be a low to middle level language; in other words, while you can program using the usual kind of stuff: functions, types, and so-on, C also makes it easier to program using assembly language (also called 'bit twiddling'). OS developers often use C because of this. They can program many facets of an OS much faster with C, but they can still get close to the metal to program the more delicate sequences.
Assembly language and the aspects of C allowing the same function are use for things like disk formatting, code optimization, drivers, and things like that. Other more high leveled languages make this more difficult. An example is the C++ programming language, which while being object oriented and based directly on C, makes it more difficult to program close to the metal.
Mostly operating system develop in c,why ?
One consequence of C's wide acceptance and efficiency is that the compilers, libraries, and interpreters of other higher-level languages are often implemented in C.
C is used as an intermediate language by some higher-level languages. This is implemented in one of two ways, as languages which:
Emit C source code, and one or more other representations: machine code, object code, and/or bytecodes. Examples: some Lisp dialects (Lush), Squeak's C-subset Slang.
Emit C source code only, and no other representation. Examples: Eiffel, Sather; Esterel.
C source code is then input to a C compiler, which then emits finished machine or object code. This is done to gain portability (C compilers exist for nearly all platforms) and to avoid having to develop machine-specific code generators.
Unfortunately, C was designed as a programming language, not as a compiler target language, and is thus less than ideal for use as an intermediate language. This has led to development of C-based intermediate languages such as C
