    fluorescent light problem

    :?: Possibly one live going to the switch and one 'switched live' returning to the light?

    fluorescent light problem

    And if the light is on when the switch is 'off', either turn the switch the other way up or (better) reverse the two browns at the switch.

    halogen lv transformers

    Steve, I can see what you're saying. I've done an exact count now and I have 53 light sources in the kitchen - 13 x 50W ELV, 38 x 20W ELV, 2 x 60W tungsten. That does seem a lot (even for a large, triple aspect room) but I never have all the lights on at the same time. I'm sure, if I...

    halogen lv transformers

    I gave up with trying to dim ELV halogen - couldn't stand the buzzing (from the dimmer/switch, not the fusebox/CU). I have ~50 ELV halogens in my kitchen (large kitchen with dining and 'family' areas), nearly all on individual transformers. Some (along line of worktops) are 50W and the rest...

    PIR wanted

    Thanks for that tip. What constitutes a 'portable appliance'? Anything that is 'plugged in' as opposed to fixed wiring? Ref NICEIC, I may be getting this wrong but I thought I need a report by a NICEIC approved person to satisfy the HIP requirements?

    Neon screwdriver earth?

    If a neon is tested on a known live conductor and illuminates and is then immediately tested on another conductor and does not illuminate, why is it not safe to conclude that the second conductor is not live?

    PIR wanted

    I want to commission a periodic inspection report on my house (South Bucks area). It's a reasonably substantial job - four bedroom detached house on three floors with four reception rooms + kitchen and garage. I don't have a regular electrician who is NICEIC registered so have spoken to one...

    Voltage detector

    Fluke VoltAlert could be OK but pricey at £22 compared to this at £9.99. May have to check them both out and report back. Also this from ebay but possibly too cheap at £3.99.

    Voltage detector

    I understand the limitations. My previous one worked well - e.g. quick and easy confirmation that I have isolated the right circuit. I'm just looking to replicate that function. The tester you linked to will no doubt do the same job and more besides - but it's not got the convenience of a...

    Voltage detector

    Any comments on this device. I thought it was similar to something I bought years ago, like a pen with red barrel and white tip, but this device seem completely useless (unless I'm using it wrongly). It seems to indicate voltage all over the place where I know there are no current carrying...

    Sizing pressure washer connection

    I don't know how these thread sizes work. The chart shows 3/8" BSP dimension F (outside dia of thread) as 12.17mm, which is what I measured on the broken lance (12mm). The internal dia is ~3/8" so perhaps that's where the size comes from. PS Sorry - read the chart wrong. It shows the...

    Sizing pressure washer connection

    Found a lance on Ebay for <£30. New washer is £100+. Anyway, I hate throwing away something that's serviceable. We (society "we") waste too much as it is.

    This is a bit more helpful than any of you lot.

    Sizing pressure washer connection

    Yes - if it was that easy I think I would have worked it out for myself. Unfortunately, the pressure washer is not a currently recognised brand and I can't track down the manufacturer, except it was made in Italy. The washer works OK but there's a crack in the lance. I don't want to have to...

    OK thanks. Can you suggest how I should go about identifying the actual type/size?

    MCB trip nuisance

    No - it's a new (1 year) split load CU. The local branch of TLC told me Wylex don't make type C MCBs and I can't see any in the TLC catalogue but, as Adam's link above, they do exist. Don't understand why TLC say they don't, unless the Screwfix ones aren't compatible. Anyway, would changing...

    Sizing pressure washer connection

    I have to replace the trigger/lance from my pressure washer and want to be sure I get the right size replacement. The fitting on the exisitng trigger/lance is a male brass thread with outside dia ~12mm. Is this a standard BSP size? e.g. 3/8 BSP?

    MCB trip nuisance

    We have a Wylex CU installed in a small retail unit. One of the ways has a 10A type B MCB that switches the window lighting circuit. The load is - 300W toroidal transformer supplying ELV to a track light with 6 x 50W fittings - 6 x small 50W toroidal transformers supplying ceiling...
