B-A-S - nice, concise, and considered reply :P

From AD P P1 6 April 2006. My emphasis. Third party certification. 1.28 Unregistered installers should NOT themselves arrange for a third part to carry out inspection and testing. The third part - not having supervised the work from the outset - would NOT be in a position to verify that...

> no gas bond, no earthing to lights That worries me most, and the LABC may well S36 the client. - No spark with knowledge of IEE wiring regs would not MEB to gas - No spark would cutoff earth wires in ceiling roses or backboxes? Or do you mean he only did a partial rewire & some lights...

You can not legally notify someone elses work. No client, employer or labc can require you to do so. Full stop. Legally. 1. LABC may choose to accept a Satisfactory PIR. 2. LABC must serve a Section 36 notice within 12 months of works completion for corrective works. This does not...

PROBLEM. That could be what the end result "looks like". However there are *MANY* critical technical details affecting the design. These are related to compliance with BS7671 AND to safety. There are no DIY kits due to those critical technical details. SOLUTION. 1. Introduction...

You want... - IEE Wiring Matters - Autumn 2005 - ELECTRICAL INSTALLATIONS OUTDOORS: A SUPPLY TO A DETACHED OUTBUILDING - By John Ware It gives a good primer on the relevant aspects. I have just been to the IET website and can not find it, perhaps someone has a direct link to the PDF...

If you disconnect one leg of the lighting ring, does the 2-way switching in the hall still work? One way of doing 2-way switching without 3C+E is to use a second wire for the neutral which returns to the CCU. That was common in the 1950s and the person may have duplicated the layout they...

> Do the cut-out tails not need to be IP4X? Cut-out tails exiting cutout do so at the top. - IP4x applies - 1mm ball/rod test Cut-out tails exiting cutout & entering meter do so at bottom - IP2x applies - 12.5mm ball/rod test Not sure if DNO equipment must meet the IP4x test on...

1. Copper can not be buried direct in concrete. - Concrete will attack copper quite aggressively & perforate - Not uncommon with u/f GCH copper pipes run in the screed - wet floor Solutions - Run copper in plastic conduit - Use PVC coated copper pipe, white for water, yellow for gas -...

"2 way cable saving method"... WTF? :-) :-) ARGH. OP... 1. BUY 6243Y 3Core+Earth from www.tlc-direct.co.uk BY THE METRE. 2. Sleeve lighting tails correctly. 3. BUY a proper book - Whitfields Guide For Electricians & Executioners still around? If you are still unsure, draw out what...

I notice from your diagram you show central ceiling roses in bedrooms. Generally one tries to fit ceiling roses by the window, that is to replicate external lighting and to avoid undesireable shadows. If you put a light in the centre and someone walks naked across the window, their naked body...

To OP. You need to buy the IEE OnSiteGuide AND a good Electricians Guide. - Problem is not what you know, but that you do NOT know what you NEED to know. - You must ensure all work complies with BS7671 IEE Wiring Regulations, including best practice, right materials etc. Domestic...

Your Vdrop is a bit high, 8.7V. - That is 40m from the shed to summerhouse - Excludes internal wiring within the summerhouse - Excludes Vdrop on the run to the shed I would use 6mm SWA. Particularly if you plan on any tools in or *running-off* the summerhouse. 17th changed the Vdrop...

1. Vdrop... Do you plan on any power tools in the summer house/shed? - If so I would use 6mm, it is only money :-) BAWAAHAHAHAHA! - Induction motors drop your voltage quite a bit during startup - lights dim 2. 17th... Distribution & final circuits require RCD protection - SWA cable does...

Very strange. Quality control on electrical stuff is pretty poor these days. The cause of failure of old-fuse & new-fuse may be quite unrelated.

> First power up main fuse went!!! > turned out pre built split load board was a duffer. Not sure how a board blows the main fuse. BS1361 63-80-100A fuse takes 800-1200A to blow instantly. During which time you are treated to a a large flash & pop. Could be a bad termination in the...

Without a photo, no-one can comment. DNO = District Network Operator which is who operates the network in your area as opposed to who actually supplies you with electricity. 1. If it is metal, it needs changing by DNO. Typically hessian covered PILC (lead covered) cable, terminated with...
