    Interesting SWA Cable

    You get all sorts of formats of SWA cables that you won't normally see as a domestic or light commercial sparky and usually if you do it's because somebodies uncle or brother in law works in for the supply authority or in a factory and they procured a length at some time. There are shielded...

    Burned wires on resistance faston connection on professional Coffe machine

    Some fast-on terminals have a higher current rating than others, you need to see the datasheet for the particular brand you're using; I've seen 6.3mm female fast-on terminals with a 5Amp rating as well as 10 Amp and I'm guessing this is because they're made of thinner material. Also avoid cheap...

    Regs and importance of following manufacturers instructions

    This does present another issue, should you be keeping a hard copy of the MI's for future reference seeing as proving compliance of that job may depend on them?

    Regs and importance of following manufacturers instructions

    A recent thread on the suitability of a cable supplied preinstalled on a manufactured floodlight/pump had me wondering a few things. Over the years the installation regs have placed more and more emphasis on following manufacturers instructions. I can see this would be fine for higher end...

    Testing ballasts/chokes

    You really need an inductance or LCR meter or a ring tester which are expensive to buy but you can make your own ring tester if you want a project to keep you out of the pub for a few nights.... Link

    Range Rover steering column motors

    According to your diagram both motors are fed with a permanent positive supply directly from fuse number 20. They also have a permanent negative (ground) connection. They then have a CANBUS data connection with the seat memory ECU which will send them instructions on this bi-directional data...

    Smaller automatic wire strippers

    Yes, 1.0mm, 1.5mm and 2.5mm flat twin cables are what I use it on, I haven't tried it on 4mm cables but I doubt it would do that size. They're not exactly cheap but I've always rated Weicon as a brand and I've had several of their tools over the years and I've always been happy with them. I live...

    How to use an extractor fan with a dimmer switch?

    If you have the dimmer on low and the fan doesn't start running then there's a good chance it's going to get hot very quickly. Most domestic fans motors are designed that their own internal impedance during a stall situation is high enough to keep the stall current (LRA) at a safe level and...

    Smaller automatic wire strippers

    Is it for flat or round cables? For flat cables I have a Weicon 7F stripper. It's fairly small and it gets into the back of backboxes very well. It doesn't exactly strip the cable flush with the entry point, it leaves about 8 or 10mm of sheath sticking into the box when it's finished. With me...

    Could you work without a smartphone?

    I have a cellphone that's about 8 years old. The battery doesn't last a full day anymore which suits me fine. I was so excited when I first got it, I thought it would help me manage my time better but it just turned out to be more of a distraction and time waster than anything else. I stopped...

    Quotation Dilemmas

    Are the customers you refer to people you've done work for on previous occasions or new prospective customers? If they're new prospects then how are they getting your business info? It maybe you're advertising is the wrong places or the advertising itself is attracting the wrong type of...

    Pest repellers alternative

    On the odd occasion we get a mouse I just use the traditional type mouse traps with peanut butter as bait but the cheap nasty ones you buy at the supermarket never work very well until you adjust them to a hair trigger by tweaking them with a pair of long nose pliers.

    BS standards webpage

    The UK public libraries should have a copy or several copies available for reference. I remember a thread about this many years ago but I can't find it now. From memory they should have a certain number of copies available but unless you live near a very big library you'll have to place an order...

    Lights suddenly get brighter in house

    I'd start by doing the usual supply impedance tests followed by N-E voltage with the installation under some load. Also visually inspect and tightness check all terminations in the CU and check the premises for any appliances with very high load or nasty ugly start or inrush currents such as big...
