Stranded can mean new (metric) or old (imperial). Taking old imperial, eg, 14th regs, 1966+. Current ratings Clipped-Direct Rarely used - 1 strand, 0.044-inch dia, 0.0015in^2 / 0.98mm^2 CSA = 12A Thin lighting off 2-way switching to each hall wall bulb - 3 strand, 0.029-inch dia...

There are 3 ways of doing EFLI measurement. 1) Calculation - Ask DNO what service type & Ze (eg, TN-C-S & 0.35ohm) - Measure R1+R2 (or r1+r2 etc as appropriate based on f.c. type) - Zs = Ze + (R1+R2) 2) 20-25A whack via EFLI meter doing High Current EFLI test - This requires a...

1. Yes, BR AD "P" Schedule 1 is the law. Compliance with Schedule 1 may be demonstrated via... i) adherence to BS7671, or ii) adherence any defined standard, or iii) any design which someone is willing to sign off as meeting Schedule 1 In the absence of a defined standard then BS7671 is...

Remedial Electrician (could be a job description there, stick their number below kitchen fitters business card addresses :-) will probably a) fit one or b) ask BCO to quote the reg requiring one in BS7671 BTW, there are cable tracers available to track cable routes. Fluke do one at about...

Re upgrading the 20A CPD. A radial wired in 2.5mm must be protected by 20A CPD (or less). A radial wired in 4.0mm can be protected by 20A or 32A CPD. A ring wired in 2.5mm can be protected by 20A or 32A CPD. It comes down to cable installation re Grouping, Ambient, Insulation & type of...

Do not concern yourself re the shower pull cord. - Provision of such is of direct benefit to you - Fitters defence that it is not required under BS7671 is immaterial to the *evidence* of falsifying a BS7671 EIC!! My point was regarding the fitters defence team :-) Just for the record...

> needed remedial work because it was noted that the shower > didn't have a pull-cord in the bathroom and so couldn't be isolated Actually BS7671 (the law) does not require it. However the incorrect CPD ratings on the EIC immediately suggests the dead & live tests will equally be fake...

Bootlace ferrules can be various shapes. MK chose that shape probably to ensure a wide contact area to minimise heating and perhaps better mechanical retention. More traditional "squeezed-square" bootlace ferrule crimps provide a slightly smaller contact area, but still acceptable none the...

Awwww, scream. - Insulation may not be compatible for the cable sheath. - Cable run thro insulation for 150-500mm needs serious derating. Running 500mm in insulation means a 0.50 derating factor is applied. Any ring cable must have a 20A corrected CCC - which 2.5mm will not have if run...

> with a plug on each end This is called a Suicide Plug for what should be obvious reasons. a) run an decent quality extension lead as required with SOCKET on the end AND verify the socket you plug into at the house has working RCD protection b) have a spark in and do not suggest your...

A not uncommon "Ooops". You say the lighting was red/black & no CPC? o Thus probably done to 13th regs, pre 1966 o Permitted with class-2 devices where no earthed metal simultaneously touchable Your new lights should be on a NEW final circuit. o This NEW final circuit would have a CPC...

A PIR is a comparison to current regulations. 1. BR & Wiring Regs are not retrospective. There is no legal requirement for the points to be rectified, full stop. If the buyer wants it a) they pay b) their offer knocks it off your price subject to your agreement c) you pay. 2. MEB (MET...

I suggest you go to www honestjohn co uk. There are plenty there who know the key faults with turbo diesels. 1. Valve problems on pumps Typically the pump is rebuildable - eg, via Delphi agents. This is particularly true if the engine is shared with Mazda. 2. Oil circulation...

For costing purposes... Cable protection... You need a switchfuse. - Typically 100A combining DP Isolator & HBC fuse - Typically made by MEM unless you want very expensive - Even so they are not cheap The DNOs service-cutout fuse is to protect their cable. They allow it to protect...

> Looks like a switched one to me Indeed it does, right of photo shows the switch outline. Too mesmerised by the red wires going to a BARE METAL screw terminal. It is more usual to get NE reversal - trips out RCD on plugging in appliance, plus the usual fishy PVC smell. I'm **STILL**...

Red wire goes to uninsulated terminal. Looks like an unswitched socket? I trust the CPD was well exercised ? :-))

Or maybe not then... Screwfix now only list the various fisher cable clips (hoops, single hook, double hook, boom) in a kit circa £25 rather than each type individually. Looks like there is not enough uptake so they vanish.
