For a couple of hundred £ you can get a basic thermal camera from FLIR and the like that will clip onto your phone and 'picture a thermal scene' nicely. The thermal part of the blended visible+Thermal image is low resolution so small hot spots may be missed. 'Spot' Temperature accuracy is...

Possibly, although I’ve never seen a professional electrician using scissor crimps as it only takes a couple of poor crimps to expose their failings . I buy good quality genuine crimping tools and as I also do coax/RF work you’re right about all the types and sizes and costs adding up...

Cheapo Ferrules usually lose their shine fairly quickly so I think they use a bit of oil or lacquer to keep them shiny until some mug buys them at '10p /1000 plus £5 postage from China '. They are something I am very picky about sourcing, as unless the material and finish is correct and it...

This is an interesting debate, so here goes. The debate is not about currently taught domestic practice where undoubtedly 'twisting interferes with torqueing, testing and fault finding' and logically it would also now require a crimped ferrule to ensure equally good connection of all...

So why the downvote @Fleeting ?

The fundamental thought for EICR's is "Is this any less safe than when it was ( at the time, correctly/compliantly) installed However this seems to be regarded as a bit quaint by people who see EICRs as a good way to drum up extra work

Lots of current TV's don't actually switch off when in standby, and may spend time updating programme guides etc before sleeping. It might be worth connecting a usb powered light or similar to the outlet and seeing if /when it goes off. My TV also powers up randomly when off to look for...

Paperclip or flattened 1mm conductor    top /bottom to toggle 

Are we in the DIY forum again ?

When you "had power installed to my shed some years ago"   did you get a certificate with test results etc. recorded on it ?  If so that may clarify the cable ratings and reasoning and whether your 'fuse' is actually a fuse (in which case a check-over the entire installation is definitely...

I was not talking about lighting circuits  -  wrapping 8 twisted stranded corroded conductors in sellotape always used to be fine there But for power and a MCB I would be betting that 99.9999999999% of competent electricians would say they they could easily torque it up satisfactorily without...

Yes its 'legitimate but tricky' to have 3 in one terminal and seems more prone to trouble on later testing,  My point was that while there's no absolute 'stop right there' point it gets increasingly dodgy and I personally couldn't look myself in the mirror if installing with 5 !    Even if...

Seriously ??    Clearly 2 are OK as Rings are OK, beyond that one or more conductor may be looser than the others or barely caught at all   - So bad practice 

For a start you would have too many cables in the MCB terminal  

Agree on 528.3 applying but unless it's an un-grounded metal pipe in 'your' tray I don't think, in normal use, that it's a clear breach.    If it was in a conduit you could argue any heating and cooling will throw out your cable calculations and choices, probably less so here, and hopefully your...

If you think you're going to drop and / or overload it to start with have look at the RS-Pro range of mid price but passable ones.  None are all that bad and their specifications are set out clearly and honestly, but the cheap ones are not as accurate (even when new)  as some jobs will require...

If you reduce the design current to 100mA you can make it work with a resistor.       if your battery was 3.6 V some cheap Chinese torches will just stick the led across it with a smaller value resistor as ‘sort of protection’ until the voltage drops  (expect to ruin a few LED and batteries...

Which also proves the second rule that even correct voltages in the right places doesn’t prove it’s right .. 

None of my last 3 cars had always on lighter plugs.   Something to do with people leaving chargers and things plugged in and draining the battery  etc  and yes for anything heavy duty like that a direct connection is best -although some of todays smarter cars use a fuse-link there at the...

Ah. With the pics:  all you can do is put the existing wires in, One in L where there seems to be a screw and L2 (oddly) which also seems to have a screw. Unless you can check at the light fitting it’s hard to say what colour runs there (the L1/2/3 wire) but it shouldn’t matter functionally.  ...
