    RCD descrimination

    This has been an interesting post to read. I would like to add that generally it is an individual MCB that is most likely to 'pop' and then require resetting. RCD's, RCBO's, RCCB's are less susceptible to tripping in a typical domestic set-up than good ole MCB's, unless you have a dodgy ole...

    lamps blowing on ring cct and lighting cct...

    Thank you all for inputs. Have been round to house now 4 times; V ranged from 247- 252. Around 70 lamps in use in house (3 bed terrace, believe it or not!), 'chandelier' in lounge has 11 ses lamps in it....ridiculous.. Told client it most likely due to a combination of factors: too many lamps...

    Does this seem expensive?

    Well done Steve for highlighting the £1750 install charge.. Alex seems to think that this is OK, but a humble spark should not earn equivalent. Not having a go Alex, just pointing something out.. Alex, you say it is a small kitchen. How small? £3000 for units/appliances alone is quite a high...

    Low voltage lighting and competent electrician

    John, you say you are getting 230V between L&N. So could be dodgy trannys/lamps. How did you check it? What did you check it with? Did you possibly check for 12V after trannys? B.A.S. You remind me of two people I know; one is a regular and pedantic client (who I like a lot), the second is my...

    lamps blowing on ring cct and lighting cct...

    Thanks Sun, Will check for more local sub around tomorrow. A lot of lamps are still designed for the old 220V common throughout mainland Europe before harmonisation I believe, so 250+V spikes will not help em! Just looked on wikipedia, apparently 'standard' mains voltage can often...

    lamps blowing on ring cct and lighting cct...

    Thank you all. PJ, nearest sub I know is approx 100m away, may be one closer though. Didn’t ask time of day though I thought that afterwards I should have done. Blows on switching and during use. From what I could gather they usually knock out the MCB. She was a bit preoccupied with sick...

    lamps blowing on ring cct and lighting cct...

    Sorry forgot to add that if V is ok still. Then am planning to ensure terminals on sockets are sufficiently tight. Any other pointers welcomed. Thanks again.

    lamps blowing on ring cct and lighting cct...

    Hello folks, Been to look at a house today where lamps are blowing 2-3 times per week. Though she may be exaggerating a lil! Lamps in question are both on lighting ccts and on 3A plug tops. Have checked some of the switches and lamp holder terminals of affected fittings and are seemingly...

    Am I allowed

    As you are the paying customer I would feel happy for you to carry out certain works to keep your costs down. Unfortunately they would be limited to securing back boxes to walls and other simliar tasks that would take very little time to do anyway. As I say get a few quotes and bite the...

    electric cooker faulty?

    Get new elements mate, they are usually cheap as chips. The outer casing of the elements may have cracked slightly and moisture has got into the powdered 'filling' around the element. Check for continuity/a short between outer casing of element and the spade connectors for the internals of...

    New Electric Shower - Power but no Hot Water

    I had the very same problem with Triton showers approx 18 months ago. Was doing the job quite cheap so it really peeved me. I took shower back and replaced it with another of same model that did the same. Rang Triton tech help and they knew nothing of a fault on this model. They said that...

    ? rewiring

    Drm, you may have opened a hornets nest here! Some very contentious points raised.... Actually no, they are not contentious! A Chartered Surveyor carried out the report. I have two brother-in-laws that are of the same profession and they would never make such sweeping statements as those...

    transformer spots or not?

    Not 100% on this Dean, but I would say that EXTRA low voltage spots are popular because they had better light renditioning and were/are more aesthetically pleasing. This may well be unture now due to advances in other lighting technologies over last 5 yrs or so. Also, ELV (12V) lamps with...

    Cable Size Question

    Plug top fuses are commonly available in 3,5 & 13A. You can also (easily) get 1,2,7 & 10A though. Not sure about 4/6/8/9/11/etc tho! What power, in watts, does your PA potentially draw? Look on back/side/or the manual of the unit. If you can find the wattage then take your power (eg)...
