Phase Rotation??

[Gastel]

Youve got this wrong, I do understand the workings......its the simplifying it down on paper so I can explain it, there is nothing wrong with trying to figure this out so im better prepared surely?? The phase rotation was lectured during the course but theres not much of it in the course books, the interview is for a permit to basically pull the fuse at the service & replace the meter. There is no way I could of blagged it this far without understanding the basics im afraid & your way of if thats what you think.

It seems too common that electricians work for years with single phase and don't have a clue how other half work.

However to fit smart meters I would have thought in the main it would be single phase. With larger supplies the telemetry part seems to be separate to the meter often needing a dedicated phone line and with the bare conductors found inside sub stations I would have thought they would be looking for a good few years experience and High Voltage qualification.

I would not like to fit meters. In the main it means working live. And there is no room for mistakes. Even though they ware protective equipment it is still a dangerous job. Those who understand what ionisation is would not want the job. My son did it for a while, and I still can't believe they sent him out on his own. I so happy when he left. Yes I know the house holder should be there but would they know what to do.

So I suppose the only people they can find to do the job are those who don't understand the dangers, or those really desperate to get a job. So it is not surprising they take on semi-skilled people who don't know the dangers.

So I would think he will get the job.

working live? are you frelling serious? ( got to stop watching farscape re-runs.. )
you pull the fuse in the house.. which is what he's getting the permit for..

if it's comercial you need into the switch to install the CT's so it will be off anyway to open it?

most of the time it will already have the ct's installed and wired so it's just a case of pulling the CT fuses and swapping the meter part..

Christ, I give up. Number 1. I have a Job,i'm merely gaining a qualification to work on the leccy side. 2. We pull the fuse at the service before we start any work, obviously checking polarity first. There is NO working live! 3. I will not be going out myself but shadowing a sparky for a month, Ive been on this course on/off for the past 3 months with Assesments & training thru out, its not answer one question in a short interview & then your out working on your tod on live installations!! Get real people!!

Well in that case you should have no problem explaining phase rotation then!

Go on, give it a crack now. Tell us all what you know about phase rotation....


PS. Even if you do find a snappy little sentence to reel off, there's a chance your interviewer might ask you to go further. What'll you do then, whip out the iPhone and say "give us a minute"?

Since my son was also required to change fuse holders I assumed you would also!

To pull the fuse you need access to main switch to remove load first many times I have found the consumer unit is not assessable which means either you don't change meter or you pull the fuse on load.

Really speaking on domestic changing a meter is quite an easy job. And with proper training I see no real problems as long as you can say no I not doing that one.

However if you need to know about phase rotation your not working on domestic. And with an installation needing three phase supplies you are talking about heavy cables, permits to work, method statements, and a need to prove you have the ability to do the work to the site manager.

There is a huge difference between domestic and industrial.

I would guess you have no need to know about phase rotation and will be domestic and may be one or two small shops and with that there is no real problem.

However I have not said you shouldn't be doing the work. And I have tried to answer your question without getting too technical so why do you want to have a go at me.

We all start somewhere and if one is able to pass the exams then you should have some idea what is safe. Other than the C&G2382 which only tests if you can read a book the other City & Guild exams do show you have knowledge and although you may lack experience you have to start somewhere.

Other than the maths you would not believe how little my degree taught me and I am sure someone doing a level 3 course likely got taught more about electrics in real world.

Eric, i agree with everything you said. Thing is there will be a shed load of gas engineers in my situation as these smart meters are kicking of big time, the utility company's need dual fuel engineers so the cheapest way for these companys to do it is to put gas engineers thru the leccy course so we can do the gas & electric meters together when we visit each house, we are only working on single phase so I dont see the need to know everything regards phase rotation etc but the sheet we got home stated on it certain headed bullet points which we must know about & have brushed up on in time for our interview, so be it.

Come on then mate, tell us! If you're wrong we can correct you before your big interview.

Think the first 4 posts tells all lovehandles,what would be the point now.... why dont you check them out if your unsure

 

[LoveRocket]

Let's see then, your first four posts (as I'm asking you to explain what you know about phase rotation) say:

Hi, can anyone tell me how to explain Phase Rotation.....what it means & how it works??

Cheers Taylor, Ive googled it but I was looking for a simple explanation from an experienced sparky,I have an interview for a permit to work next week & one of the questions is on phase rotation, I'm just looking to memorize a simple answer, any help would be appreciated.

Take a pill holm, its the simplified wording im looking for not the overall understanding, ive already sat 5 exams & 3 practicals to get to this point...i'm a gas engineer who's being put thru an intense course which allows me to work on electric meters, cheers for the concern though

Your patronising knows no bounds.....now run off & play with your lego t1tlaw

Now none of those explain phase rotation.

I don't know why you're getting so arsey about my question, you say you know all you need to about phase rotation, and I'm giving you the chance to test yourself (and be corrected if needed) before a job interview where you will be asked about this very subject. (or when asked will you tell the interviewer to refer to this thread?)




PS. Sorry for the Banal style post.

Ive been thinking lovemuff, your right & I think your always right.....Ive just phoned my boss & told him to forget putting me thru this stupid course, what was I thinking, P45 now in the post......phase rotation is not all its cracked up to be, too much for me i'm afraid.......I just dont get it so why persist, cheers love x

Hmmmm, still no answer.
