  2. Best prepayment meter option?

    I had this problem with a house my cousin owned , two flats , up & down. He would have had to purchase a load of swipe cards , then sell them to the tenants as & when ....he didn't want that . The only cards the tenant can buy at local shops are the ones that work for the major utilities . I ended up with some half decent cash meters which I shall now try to find details of ....watch this space. Edit : I cannot find data on the ones I fitted .....typical You could try :- Universal meters . or Westwood Meters & Timers www.electricmeters.co.uk
  3. Radial circuit

    No just altering an existing radial by shortening the run by 5 mtrs, it is now circa 12mtrs total length. The original circuit was about 17 mtrs and was feeding to 2 x 1500 watt wall mounted fan heaters via a 16amp cartridge fuse which is intended to be used.

  5. HELP REQUIRED WIRING CONTACTOR PLEASE

    No not like that . When you say A/C unit are we talking about an Air conditioning unit ? What is this pump for ? What ever you are switching would be Incoming L & N to L1 & L2 ....outgoing L & N to T1 & T2 ( Pump) You then need to apply a voltage to the coil to make the contactor switch in & out ...that will be , as Andy says , a L & N onto A1 & A2 . Where that comes from I have no idea as we don't know what you are doing .
  6. Danlers do one https://www.danlers.co.uk/outdoor-security-switches/26-products/outdoor/outdoor-security-switches/109-copd-compact-person-detector
  7. On the old 2 gang switch was the 2 way for upstairs light and the 1 way for downstairs light? And are you replacing it with a 1 gang 1way? You may have 2 different circuits on different sides of rcd's and by connecting them together it will trip the rcd
  8. Tryed vlc player and no doesn't play I think it something to do with super player the one off the Dvr dosnt work but someone gave me another link same thing but that worked .
  9. Van Vault

    you could always try the old fashioned way, like look under the van to see whats there
  10. looking for practical experience

    To say that replacing lost certs is a bugger it is the understatement of the year. I can back up your comments wholeheartedly.
  11. You could utilise what you have put together and do some dead tests for a bit of practice. Add some resistors to your ring circuit, put one in series on each conductor on the circuit, power resistors will be better because you could insulation resistance test the circuit and eventually move onto live testing. When you have put the resistors in ( I suggest 1ohm) you will be able to take accurate readings, follow GN3 and complete the 3 step test and see if your results compare with it. You should have 1ohm end to end and 0.50 ohm on steps 2 and 3 at each socket outlet, see if you can work out why.
  12. Memlite Lamp restoration

    Be careful if it's French......it may completely "give in" part way through the restoration
  13. Evening all from Leeds.

    No, things have moved on and changed over the last few years. Get the latest GN3 and download the free GS38. Study them and get your head around basic electrical theories like OHMS law, and insulation resistance theory and you wont go far wrong. Murdoch, most will opt for 2391-52 and this will be what employees ask for, and is also the must have for QS positions. The -50 and -51 will be top ups for those who have either 2394 or 2395 and need to fill the gap.
  14. If you are ripping out the kitchen anyway, then I suspect most issues can be resolved with that work. Cable at nearly 50 years old is going to be nearing the end of its life - testing will ascertain if its any good or not, but as there are no diffinitive guidance on cable life, the test resuts will be open to opinion regardless (in theory anything that passes test is good for 10 years). As stated above, it would be worth resolving any issues like hidden JBs before fitting new flooring. As Pro Dave has said, it may be possible to refurbish rather than full re-wire, but it isn't that much of a cost saving in my opinion. A full rewire could be done in stages, ie start with kitchen, new board and replace feeds to upstairs sockets / lights whilst trashing kitchen. Then extend works from that on a room by room basis - this saves damage to decor in every room and having to live with that until a room is ready to be redone, unless you are lucky enough to be able to afford to renovate whole house in 1 go
  15. Cable size required?

    i wonder if this 10mm is really 6mm...
  16. USB outlets in sockets

    Well a sparks I know has fitted a house out , virtually , with them . If you were testing it would be disconnecting them all and refitting them after L - N tests.
  17. Thousands of people in the electrical sector are faced with a wide range of difficult situations in their lives, which often lead to mental health issues. Some of those affected reach out for help, but others have no one to turn to and often bury their struggles in alcohol or drug abuse. Addictions such as alcohol or drug abuse often not only have a dramatic effect on physical health but also have significant impact on mental health which often leads to problems such as depression, anxiety, and many other issues. Recent statistics released by the NHS showed that in the UK in 2015/16 there were 8,621 hospital admissions with a primary diagnosis of drug-related mental health and behavioural disorders. It was also recorded that each year there were 2,479 registered deaths due to drug misuse. The National Institute on Drug Abuse (NIH) also stated that compared with the general population, people addicted to drugs are twice as likely to suffer from mood and anxiety disorders. To help to reduce these statistics and to give crucial access to support services to those who are affected by mental health problems, the Electrical Industries Charity has created the Employee Assistance Programme which offers all of the vital support needed to help people in the electrical sector to get back on their feet and create a life they deserve. Recently the Charity helped an experienced electrician Rhys Lynch to create a better quality of life for him and his daughter. Rhys first contacted the Electrical Industries Charity in 2012 when his partner left him and his two-year-old daughter. Rhys applied for sole custody of his daughter, leaving his job as an electrician to become a full-time parent. On gaining full custody, the council re-housed Rhys and his daughter into a one-bedroom property, and the Charity provided a £1,000 grant for household items. In 2013, they were moved to a bigger, two-bedroom property, which better met their needs and once again the Charity helped, providing a £1,000 grant for flooring. Despite starting a new life, Rhys’s problems were far from over. Over the years Rhys was faced with numerous financial struggles which sadly resulted in him turning to alcohol and drugs and in 2015, Rhys lost not only his home but also custody of his daughter. With nowhere left to turn Rhys resorted to theft to feed his addiction, and following many incidences, was sent to prison for 14 weeks. After serving his sentence, Rhys suffered a further relapse and nearly lost his life. Since then he has sought counselling and support for underlying issues which dated back many years. The Charity once more offered support to help with his debts, and he was granted a debt relief order (DRO). Since September 2015 Rhys has been free from drugs and alcohol and can now see a brighter future ahead. But the road to recovery is never easy, and for people suffering from mental health issues, ongoing support is vital which is why Rhys contacted the Charity once more in January 2017. The Charity helped with the cost of updating his qualifications through Able Skills and as a result he has now passed his 2394/95 City & Guilds Testing & Inspection course. He has secured a maintenance contract with a local Estate Agent and been offered a contract with a local construction company. Thanks to the support and financial assistance provided by the Electrical Industries Charity, he is once again living with his daughter and is well on his way to building a better life. Rhys’s story highlights that seeking help and having access to support services can remarkably change someone’s quality of life and this is why the Charity always ensures that people in the electrical sector get the support they need when they need it.

  18. Specifiers working on the Irish project required a high performance containment solution that accommodated a large amount of data cabling, was aesthetically pleasing and provided streamlined cable management around difficult corners and protrusions. Innovative PVC-U Twin165 delivered the perfect solution, with a large bend radius control of 50mm suitable for installations up to Cat 7a. The trunking is split to provide 60% of space for power delivery and a generous 40% for data cables, making it perfect for commercial requirements. Electrical contractor Matt Potter of Red Mechanical & Electrical, Newtonabbey, Belfast, said: “The trunking had to be Cat 6a compliant, meeting certain bend radius figures and because of the deep profile of Twin165 we were able to achieve this. The trunking was installed rapidly and we found the Marshall-Tufflex products competitively priced and in stock with our supplier.” Around 500m of white skirting and dado trunking were fitted throughout the 130,000 ft² site, supplied by Wilson Electrical. The durable system has pre-drilled fixing points making it quick and easy to install. Unique, lockable and adjustable internal and external bends mean it is flexible enough to offer adjustments of +/- 10% for intolerances on corners. Core Electrical is the sole distributor of Marshall-Tufflex products in Ireland and Northern Ireland. Marshall-Tufflex manufactures and supplies a comprehensive range of PVC-U perimeter trunking systems to ensure that whatever the building design and specification there will always be the perfect product to suit. As the UK’s leading manufacturer and supplier of cable management systems for the building industry, based here in Britain, we are dedicated to achieving high service levels and reacting quickly to your requirements. Our network of sales engineers is supported by advice from our technical team to ensure that you receive immediate assistance and complete peace of mind.

  20. Question about display panel on SB 2000 HF

    Depends how he checked the panels. If he disconnected the +ve and -Ve at a sunny part of the day, they maybe correct. If it was checked at late afternoon ie getting dark, you would not always see a full voltage even in open condition. If he checked the voltage with the strings still connected and inverter turned on, you wouldn't get the OC voltage becuase the inverter would be trying to convert the eenrgy which drops the voltage and raises the ampage to get power. But the fact the inverter is showing nothing, not even the grid voltage would suggest that the fault lies there. If there was a break in the DC you wouldn't get a voltage at all except in reference to earth, and if there is an earth leak, you get a steady volatge in refrence to earth as the fault allows current flow. It's a bit hard to comment without knowing exactly what they did. The other possibility is failed by-diodes in 3 panels, but that wouldn't stop the inverter working. I have to say fault finding solar is still a relatively new skill, and it isn't always very obvious how to proceed, or what certain things mean. Having had very few faults with systems I've installed, I'm still learning myself, but obvious issues are obvious issues and no display... HOw easy is it to access the panels? If it's aquick shim up a ladder to a flat roof it's easy enough to check the connectors yourself. Another daft question, have you turned AC and DC isolators off and re-booted the inverter? Is there a non-flashing red led on the generation meter indicating the cct is live? Inverters are a bit like computers, sometimes they just need a kick up the arse! Turn off, leave for about 5 mins to discharge the capacitors, then turn on. YOu should then see the boot up sequence on the display. See below. 2nd video is later model but in English
  21. Anyone else had this dilema before ?

    Hager's REC (VC02SW) offering only allows sealing on the supply side,,,
  22. 👍 another way would be to take the 2 wires out of Z5 in the panel and put a wire link in their place shorting out the zone the end result is still the same
  23. This Q & A is one of thousands posted in our Technical Expertise area, and answered by our Voltimum Experts. Question: Hi, I am carrying out an EICR and there is an old rewirable fuseboard present which is full to capacity. It has a fuse which has two ring mains connected to it. Cold you please confirm if this is a C2 or a C3 coded observation? Thanks, John Answer: Assuming no other departures were observed on the circuits during inspection and testing you would need to consider regulation set 314 ‘division of circuits’. Where you can achieve compliance with 314.1 (i), (ii), (iii), (iv), (v) and (vi) our guidance code would be a C3. Where there are rewirable fuses the absence of RCD’s where applicable would need to be considered and comments on the full capacity of the consumer unit could be made.

  24. Pumped storage:

  25. This Q & A is one of thousands posted in our Technical Expertise area, and answered by our Voltimum Experts. Question: In a new installation, I found 16 mm mains tails have been installed at a length of approx 12 meters between the meter cubicle and the consumer unit, they are protected by a 100 amp supply authority cut-out. Is this cable run too long?Should the tails be a minimum of 25mm? Answer: BS 7671 permits the electricity distributors cut-out fuse to be used as a means of overcurrent and fault protection in compliance with 433.3.1 (iii) and 434.3 (iv) providing the electricity distributor agrees. Although most electricity distributors will agree to their cut-out being used the typical maximum length of meter tails is 2 or 3 meters. Generally installed meter tails are 25mm. A smaller diameter such as 16mm would be permitted providing the cut-out fuse is sized in accordance with section 433.1.1 of BS 7671, where the rated current of the protective device does not exceed the current carrying capacity of the meter tails.

  26. Project Bank Accounts, have you heard of them?

    Many moons ago I was in the procurement department of a multinational company, they were notorious for late payment. We desperately needed a 300A LSE (Laurence Scott Electromotors) contactor. I ordered it and waited………… Finally I phoned LSE “we’re sending you nothing until we get paid for the last three orders!” A bit of digging around and I found out LSE bought in the contactors from MCS (Manchester Contactor and Switchgear) so I placed the order with them. Strangely both LSE and MCS went bankrupt.
  27. This Q & A is one of thousands posted in our Technical Expertise area, and answered by our Voltimum Experts. Question: I carried out an EICR for a holiday home in Scotland and was wondering if there was any regs regarding emergency lighting and smoke alarms for this type of property? Previously, the flat was rented out to long-term tenants and they have had a main heat sensor in the kitchen interlinked with the one installed in the hallway. I was thinking that a smoke alarm should be added to the bedroom and db room along with some emergency lighting, just like a hotel. Any thoughts would be appreciated. Thanks Colin Answer: There is no specific regulation relating to this type of property however there is BSD guidance on small premises - the design of any system should be done on the basis of a responsible person carrying out a fire risk assessment.
