The electricians guide to the building regulations will have answers to all those questions :wink: http://www.amazon.co.uk/Electricians-Building-Regulations-Electrical-Dwellings/dp/086341463X regards

That wire will be outside the safe zone. Regards

If the switched live has not been sleeved you may have thought it was a neutral and connected it as such. Every time you swich the light on you will be shorting live to neutral and blowing the fuse. Regards

It would have been wrong for someone to put a junction box in the wall but that doesnt mean it hasnt been done :) As for connecting at the ceiling rose, they dont usually have enough spare terminals to feed an extra light, and I think its considered a no no to put two wires in one terminal at...

Always a good idea to test at 250 first, just to show up any loads. If your tester doesnt have a 250V setting then do a continuity test between conductors to confirm there are no loads present. Regards

They must have got carried away with copy & paste :)

Surely junction boxes would be better than ceiling roses :? A ceiling rose has cable entries from the rear so do you plan to drill holes in the beams? Correct me if im wrong but I thought it was not allowed

Its a watered down version of 2391 and is aimed at candidates with no previous experience. There is no written exam, only a multiple choice according to this webpage: http://www.proactivetechnicaltraining.co.uk/course_2392_10.php regards

1) Calculate the design current (Ib) 2) Select protective device rating (In) 3) Select cable from table after considering correction factors (It) 4) Calculate volt drop 5) Calculate fault loop impedance (Zs) 6) Calculate fault current (Ia) 7) Determine CPC size 8) Assess PFC For...

In theory if you had 4 lamps of equal wattage wired in a ring, there will be no current flow in the cable between the second and third lamp. So no real point in the cable being there unless the MCB for the circuit is too large for a radial. I was told that rings were designed as a cheap...

If you do R1+R2 and flick switches while your at it you then prove polarity at the same time :wink: regards

For anyone whos interested there is an artical about plastic pipes in one of the wiring matters magazines published by the IET. Here is a link to that artical: http://www2.theiet.org/Publish/WireRegs/WiringMatters/Documents/PreIssue14/1999_6_autumn_plastic_pipes_to_bond_or_not_to_bond.pdf...

Yep- guilty as charged! :D I couldnt even be bothered to edit the mistake I made with quoting

Are you expecting the pro to sign an installation certificate for work that you have done? I would be suprised to see that! You can get an installation report done which is something completely different, and may even assess the installation as unsatisfactory at the end of it.

Using insulating tape is classed as site applied insulation, therefor according to guidance note 3 it requires a 1500V flash test (or thereabouts) :D

Here is some info for use as a guide: wiring matters Regards LG

1) Rachet type with adjustable compression (look for a star shaped adjuster on the tool handle) 2) One that crimps the same in both directions unlike some that need the wire to enter from the left side only. Ones that crimp in both directions are easier in arkward spaces regards
