Having done retrofits for tubes on a quantity amount, I would say replace rather than retrofit. You get problems like the tube holders breaking due to age and poor fitting with worn copper terminations the pins. Time wise it is about the same to strip out a fitting and replace. Modern led...
I think it means that it should be plugged into an ordinary socket outlet which is rated at 16A and the appliance is protected by the fuse at 13A so a bit of a nothing-burger really.
I think the term is discouraged as it does not fit within BS7671 requirement to use BS standard or harmonised standards as per pg. 100 on site guide. Anyway having seen sy cable used in a few installations, especially outside, I am not convinced of its robustness or suitability especiall...
Well I know I would not sign off on SY cable. As it is not standard (BS) cable it would be hard to justify using it as it would be a departure given we are required to ensure accessories and cabling meet those standards. Descriptions of poor termination and inadequate attention to glanding again...
Din rail is ok and I have used it for RFC in a CU. The only snag the MCB/RCBO cant go onto the live bus bar, it has to have it's own supply from the din rail meter. So it can be a bit of a fiddle and would have go at the end of the MCB/RCBO if you see what I mean. But in its own separate...
Well we know the light is ok as it does switch on and off. So it is the switches. One of the wires has probably come out at one of the switches. If not that then it was always wired wrong. You should have a two way switch at each end and an intermediate switch in the middel. Sometimes called a...
I think manufacturers should certify and test their fans. They should give a certifcate with the fan you buy to show it complies. It seems once again we are being asked to do manufacturers work. /sigh!
What do you mean "...my motherboard had blown..."? Are you saying there was an explosion of capacitors or melted components? Or is that the BIOS was damaged or what exactly? Did the electricains PAT test your extension lead/products? Does anyone else living near you have a smart meter? In my...
The only appliance is heating that might go up at night but as you say heating is not electric. Maybe radiator pump? What temperature is your thermostat set to at night? Pics please
If you are thinking of a new circuit for the cooker etc., each new circuit will have to be upgraded to modern regs. So a new box is pretty well inevitable. I find that nowadays as the manufacturers who make the devices we are increasingly forced to fit by regs, also make the items we are...
As to safe to use, well I have never accepted the idea of water and electricity being used together. Never mind voluntarily standing underneath it, never really sits right with me. Personally I would want an RCD on my shower for safety reasons. If you are upgrading the shower you may find that...
Regulations are not law. Items that were installed that long ago are subject to the rules/regs extant when they were installed. As to modern standards it would no doubt raise eyebrows. Breaking it down a bit; 8.5 kw equates to 37 A so you are potentially running over the fuse capacity. However...
Is it the plastic part that you slide or the metal part the plastic part moves off of the contact? I should think I could rustle up some for a merlin gerin board as I replaced one not long ago and left the box for spare parts. Maybe you could get them on ebay.
The value recorded on the test sheet is 1.37 as this is the maximum permitted value for a 32a MCB RCBO. However when testing the "rule of thumb" is to use an 80% value i.e. 1.06. When calculating the cable size the tabulated value will need adjusting or rating down (usually) to take into account...
Usually they promise the earth and deliver very little. The forum is replete with stories of being ripped off. Industry entry requirements have been strictly upgraded and now you need a level 3 with portfolio and AM2. You cannot be entered into a competent person scheme without meeting these...
