Wire up off on and emergeny switch on my drill
Twinsquirrel:
Agreed, the "little knowledge" part is something I am guilty of.
--- Quote ---All this is purely accedemic as it is now illegal for anyone without a current IEEE/IEC certificate to modify the wiring in any dwelling or business property. You can however install wiring etc and then have it checked by a current (no pun intended) qualified electrician who will sign it off before it is connected to the supply.

If you are in the UK take note of the above otherwise you will be breaking the law and probably very dead.

I think you are all being a little paranoid here,
There is nothing in UK law to stop you wiring or altering the wiring of your own home and premises apart from in kitchens and bathrooms.
The rules state any competent person may carry out these alterations, they don't state what is regarded as competent though.
Different if you are doing it for financial gain of course.
Same goes for gas, any competent person. Though Corgi would have you believe otherwise.
Besides, they are not recognised now anyway. Got thrown out, some new regulating body has appeared.
On another site we discuss high voltage valve amplifiers, their circuits and how to build them. High as in 250-1,500VDC though I do tend to use higher voltages myself occasionally.
John Hill:
Um, dont think I am paranoid. Although my electrical registration expired in the 60's the basic principles will not have changed and I know how a dangerous situation can arise especially in a workshop which is quite different to the typical domestic situation where things like earthing are quite different and are more akin to the kitchen and bathroom than the rest of the house.
I also understand, though dont know the details, that wiring colours have been going through a period of change in the UK which no doubt leads added complication to anyone who is not thoroughly up to the play.
However, I am not competant in the UK electrical scene and will not give any advice over what I have already done and that is to be very careful and not accept that it works as proof the situation is safe.
BTW Darren I just sold a Collins radio transmitter to someone in the US, it took me all one weekend to make the two crates and get them to the shipping company. It has a 3000Volt HT power supply and stands in a full height cabinet with a glass window in the front so you can see the colour of the PA Anode! Circa 1952.
Darren:
Hi John,
By paranoid I wasn't referring to the safety aspects, more the who can and who can't work on the circuits.
One of the major retail outlets B&Q will sell you almost anything electrical required for the home environment to any member of the public. If Joe public wasn't allowed they wouldn't be able to sell it to you.
I agree, electricity can be very dangerous in the wrong hands, but then so can our machinery. In fact many of our home machines would never be allowed in a work place. That's how come we can get them so cheaply. Different rules apply.
But it's like anything else, if you don't understand what you are doing then you should either educate yourself if so inclined, or leave it to someone better able, pref qualified to do such work.
BTW, the "new" colours are not new, they have always been around. They just changed the colour of twin and earth cabling to match other types.
Neutral is bonded back at the power station in the UK. Very few homes have the old system of an earth rod today. But please, do make sure "ALL" your machines are earthed properly if you do nothing else. Your life "will" depend on it at some point. After that make sure you have some sort of safety trip device, RCB's, MCB's etc.
What ever you do do not run a twin and earth to your workshop for power. Used armored cable.
If in doubt, let a professional do the installation and make sure you get one in to give it the once over. You will need it for your insurance etc.
Nothing in the home wiring is complicated, but you do need to do it right.
If you don't understand the principals, then please don't do it.
But then again, the latest British Gas advert most of you may have seen on the telly recently shows you a sure way to kill yourself and no doubt any linesmen working on any power lines in your area.
Tut, tut.....
Twinsquirrel:
Interesting Darren, My info on wiring was what was told to me by the sparky who came to wire the lights etc in our conservatory, it seems he gave me a bum steer and was just trying to protect his own business/trade. The law changes are explained here http://www.diynot.com/wiki/electrics:part_p:diy_electrical_work_and_the_lawand I have to apologise passing on dodgy info.
Just to avoid confusion my earth stake just augments the existing earth running in the armoured cable.
