    3 Phase Supply Conversion - Needed or OTT

    WHat you should do is confirm whether your supply is looped, i.e. a cable off the street main goes to one house and on to another, it was quite common on new build developments in one era 60s/70s? . But these days the DNO are supposed to unloop you for free if you are planning on having an EVSE...

    Told I need to have Ze checked, an R1+R2 test, and possibly downrate a 40A fuse to 32A - any way to save money here?

    It looks like everything is RCD protected, so the risk of a high resistance suppliers earth is a lot less than if it wasn't. An RCD can actually be used as fault protection, but this is generally discouraged in TN systems, and definatly not really the done thing when you suspect there is a fault...

    Told I need to have Ze checked, an R1+R2 test, and possibly downrate a 40A fuse to 32A - any way to save money here?

    Are you able to post a picture of your mains intake and consumer unit area, so we can establish what earthing system you have, and what you have in terms of RCD protection If you have an earth provided by the DNO they are obligated to maintain it. If you are getting high loops on sockets as well...

    Downlight Wiring

    Theres nothing wrong with your desired layout, the only issue you are likely to have is that don't think many downlights will accept 3 twins very easily, so chances are you'll need to use some kind of joint box, in which case, you should locate it at that downlight position so its easy to get...

    The Magnetic trip coil in the MCB acting as a choke, possibly? Would have been interesting to see if changing to C curve MCBs made any difference or not

    CU at an angle

    What is the width you have to work with?, some makes do a double stacked unit which is 300mm wide which seems about the same as their 10way single row boards, but dimensions do vary between brands, so would need to know what space you actually have

    Old Consumer Unit…..

    Ah, stop being so pessimistic, it might not be a VOELCB, it could be grey, in a dark grey enclosure/cover which screws into the drive top and bottom with massivly oversize sized poorly created cable entries through which you can see the terminals* and have a small white test button, and the ON...

    Maximum OCPD for SSSO

    Come across this a few times, I'm not aware of anything that says it can't be done, but I've never been been keen on it, given the ease that one can trap a cable in a metalclad fusespur when screwing it back, or on some makes when pulling it forward depending on placement of terminals. Its...

    ARMOURED CABLE QUERY

    I Can see 1 on the core that goes to the first MCB after the incommer, and 2 one one of the ones that goes to neutral. I cant see anything on the others in the picture but chances are you could if you turned it around. However that picture raises more questions; why is the supply to that board...

    ARMOURED CABLE QUERY

    SY cable is widely mis-used, it doesn't actually meet any standard for either the Uk or the EU as a whole, its made to some german only standard, and its generally intended as an EMC screened cable while may have some used on production machinery, doesn't really belong in fixed electrical...

    Garage electrics

    Is this a detached garage? There being a switch for the garage light in the house might ring faint alarm bells, I've come across two instances where a 4core was run to a garage, two of the cores being L&N of a submain to the garage board, and the other two being the strappers of a two way...

    bathroom lighting , wall sconces.

    His corncern was related to the positioning of the fittings and the lack of additional RCD protection, so just how will replacing the fittings help with that, also given this was posted in 2010 and and the chap is no longer a member he, I am unsure how you felt this would be usful.

    Fixing USB lamp - wiring help

    chances are you'll have two separate positives from the lamp, one for each group of LEDs and a common ground. From the supply, you'll have positive and ground. Now if I was designing it, I'd have black as ground from the LEDs, in which case, you'd want to join through the two blacks, put the...

    What kind of MCB is this?

    Just because they have been over-zealous with their sealing, it doens't follow that you have to feel the least bit guilty when chopping the extra ones off!

    Can I Isolate This Setup?

    That was actually possible, and whats more they could tell what channel was being watched. Its possible to pick up leakage of the intermediate frequency from the local oscilator in the TV, and if you do it with a directional attenna you can pin point which house to some degree. Unfortunatly it...

    Wifi extender running on electrical cables

    It makes use of powerline networking in some way or another (possibly by using it as backhaul between nodes?) powerline networking has existed in one way or another for at least twenty years and somehow super imposed data on the mains supply, its not liked by a lot of folk because it generally...
