Domestic electrical installations that is, that first my LEB electrian uncle Reg taught me at 14 years of age, and continued to do with my ex, studying the regs. and watching / talking to professional electrians to learn modern installation testing.
I have just completed the extension to two ring mains, installing some 7 double sockets, channeling out the runs, with the installation of metal conduit. All tested and working to design, and very satisfied that I can now power all electrical appliances in my bedroom and lounge without the use of dangerous extensions, along with 3-way adaptors!! :D :D 8-) 8-) 8-)
Thank God from being a young girl I was encouraged not to rely on anyone but myself for electrical installation, plumbing, car mechanics, decorating, cooking, interior design, sewing, kniting (although I haven't got the patience now for the latter two!!) and child care!! :D :D :D 8-) 8-) 8-)
I (we, when he was around :'( :'( :'() saved a fortune!! ;) ;)

well done lizzie :y

It is amazing how many I have met on my travels Opti! :D :D ;)

....... & all Part P tested! ;)
-
....... & all Part P tested! ;)
Yes! :y :y
I was lucky. I first tested all the circuits, then the electrians who are testing the electrics in all our flats tested my system in total. Job done at no expense to me! :D :D :D 8-) 8-)

Yes! :y :y

Excellent Lizzie. When I was a young lad my mother taught me how to look after myself :) and to prevent to be taken advantage of. :) I really thank God for her, and if carrying out any job to do it well, as a good tradesman will never be out of a job. :y

I know that well as both my mum and grandmother believed in doing everything they could themselves and always stated "if a job is worth doing it is worth doing well"!
So it was logical for me to learn everything about doing jobs myself in as many fields as possible, and by golly has it paid off given what I have seen so called "professionals" get up to!! :o :o :o ::) ::) ::)
The males in the lives of both of my great grandmother, grandmother, and mother on that side of the family were useless at doing anything! In fact my father couldn't even bang in a nail straight! ::) ::) :D :D :D

Did they give you the certificate to file away somewhere?
I understand that they are supposed to send them to the local council planning dept - but am not sure if that's 100% or not.
Well done.
I had a pal of mine around a week or so back. He is fully qualified and converted the house to use a single phase of the three phase supply as it was using all of them!
Defo not a job to get wrong ............

don't worry Opti - I'm quite sure Lizzie asked a man to check it really :y

Well as said, I did all the testing myself, with my work conforming to the 17th Edition wiring regulations, Part P, but yes as luck would have it to make it all "legal" under modern regs. MALE electrians yesterday did a full testing of all my electrical system as part of the works they are doing for my landlords and it all passed with flying colours :D :D :D ;)
Result, as yes as officially an "amateur" electrician, albeit a trained and educated one, I needed for legal reasons to be covered by the professional testing. A confirmation of the test date has now been put on my consumer box, with no doubt the test certificate going to my landlords.
Proper job!! :D :D :y :y
To anyone not confident, experienced and trained to carry out such work I recommend you do not! Safety must come first :) :)

Agreed BJ......better to be safe than sorry.... ;D ;D ;)

I have a cable that needs checking. :-* :-* :y

Good on ya Lizzie. I can saw out & fit the metal conduit casings, then re plaster but leave the final wiring to a sparky.
If i tried it you'd probably switch the shower on & make 2 slices of toast!!!! ;D :D ::)
-
Nice work Lizzie - What about the completion of the job, have you matered plastering as well. :-* ::)

Yes Skruntie, I can do a limited amount of plastering, but obviously this time it is just a case of filling the channeled out runs and smoothing over. Need to get to B&Q now to get the right plaster, after which I will be puting up the coving ;) ;)

Wished you lived closer to me, I have lighting for each room that needs fitting. ::)

I would do all that as well Phil! :y :y :y
But I must admit my body feels the effect of this kind of work now where as 20-30-40 years ago I could keep pace with anyone, including my ex who could work all hours on business, then work on the house during the night! :-* :-* :-*
But now my mind can still do it, but my body says otherwise! :'( :'( :'( Still my nails are still intact, and I have one bruise where I missed the chisel head with the hammer 3 times and stopped it with my hand!! :o :o :o :'( :'( :'(

i dont know, you might need an extra socket fitting. after all these do take quite a lot of power.

I like that. It's in my photobucket album now and may, at a later date, make another appearance. ;D ;D

I've tried one - total pain in the arse :o

Lizzie, is there anything you're not good at? I mean really, I can't think of a woman who can do as much as you :o :o

Thank you Del, but yes there is sooooooo much I would love to do, but now realise in horror that I won't due to running out of time!!
Everything I can do has been done out of necessity, going back to the times when pennies were in very short supply, right into the days of having a young family and working, with my ex, all the hours God sent! :P :P :P :P
My one big regret though is that I was not intellectually good enough to become a medical doctor, and a paediatrician specifically. I would loved to have spent my working life surrounded by babbies and young children, working on their illnesses, instead of talking about profit and loss :( :( :( :(

A mate of mine just got a quote. From the pole next to his garage to his garage was going to cost £7k excluding groundworks to put in the ducts for the cable, etc. :o
Needless to say, we got an inverter to power his 2 post lift.

On a practical level is there any advantage to be had with a three phase supply to non commercial premises.
Over and above that. can anyone explain (in language easily absorbed by this idiot) what the difference is between the two? (Other than one being single and the other being triple of course)

Essentially, you can transfer more power with less copper in the cable for a given amount of power loss in the cable, which is why most of the transmission network is 3 phase.
In terms of its' advantages to the consumer, you can make a 3 phase induction motor much more efficient than one operating from single phase, both in terms of power consumption and physical size.
Because the power is delivered to the load constantly, rather than with a 100Hz interruption in current flow, vibration in motors and other equipment is reduced and applications where the mains is rectified to DC work much more effectively on 3 phase power.
Think of it as power delivered from a proper V6 engine (a power stroke every 120 degrees) as opposed to a 2 cylinder 4 stroke engine (2CV / Fiat 500?).
For this reason, and because, for large loads, it's important for the supply network that the load is evenly balanced between the 3 phases, the 3 phase mains from the grid is continued into the premises for industrial applications but a home is typically fed only one of the phases.

Yes, with each phase cycle, 1,2, & 3 timed to run outside of each other :y :y But Kevin, shouldn't that be 50 Hz, not 100Hz per second? :-/ :-/
You can apparently save money using this system, but the cost of installation is prohibitive to most domestic customers ;)
-

No. Power is delivered to the load on both the positive and negative half-cycles of the AC supply but drops during the zero crossing of the waveform. :y

Thanks for clarifying that Kevin :y :y

All I know is, I don't mind messing with single phase power.. but the thought of messing with 415V with the potential for something like 300A scares the bejeezus out of me.. ;D
-
I asume you have done it to 17th edition regs lizzie, LOL.
As for female electricians i used to work with a few on british gas they did a dam good job. :'( :'(

To add to Zulu's request for info, my recollection is that its 3 phase supply through the pole/underground network at 440volts or thereby at street/housing estate level. If you take any one pair of the 3 cables and run them into the houses, you then have single phase at 240volts or so.
All other explanations as per Kevin and co are obviously valid. :y

Turning on my old 1ph. Quasi-Arc 'static' welding set (400 amp./90 OCV. transformer) makes a tremendous 50Hz. 'whump' and visibly dips my (& my neighbours) lights on switch-on......
......"She`s at it again, Maureen!" ::)

very impressed , so many bits of paper that have to be passed to do enything nowerdays, :y

Thank's to Kevin and H for expanding on my question about the 3 phase supply. 8-)
I have now grasped the basics of a thing that has puzzled me for a wee while now. :y

Almost. ;)
We have 400V 3 phase in the domestic supply network these days since harmonising voltages with Europe. Between any 2 phases you get 400V AC in such a system. Between any one phase and Neutral you get 400 x Root(3) volts = the nominal 230 volts we use domestically. :y
If the phases are in balance the current through the neutral conductor cancels out, so for much of the network there is no neutral conductor required (look at power lines - the wires are in multiples of 3).
In a domestic setting, the balance is less good on a local level so the transformer in the local substation is wound to provide a neutral connection.
