    Calibration - What actually goes on?

    Stupid thread time. We hear a lot about getting meters calibrated and checked regularly but not a lot of detail about what is actually done. Is it just testing against preset levels? If a level is off (beyond tolerance), how exactly is it corrected? Would love a point to point on exactly what...

    The apollo advanced mx pro panel is showing an error that a smoke detector is faulty but it seems to be blinking properly.

    The detector is working properly. We have checked it physically. But the pannel is showing fault in that detector. Please give me a solution

    Do electricians actually need to have the 17th Edition?

    Hi All, Just recently I have had my interest in electrical work re-awakened because I have a grandson halfway through his apprenticeship and I asked me for help. The electrical technology was OK as very little of that has changed, but BS 7671 was new to me and so I got stuck into it. I...

    Mains Frequency huge Variation

    Hi, on my mains I seem to be getting huge variations from the normal 50hz for several minutes at a time.

    Low watt led gu10/mr16

    Excuse the ignorance (and laziness), but what's the lowest watt (equivalent) you can actually pick up? Want to put a perimeter of downlights in to use instead of lamps so obviously want reasonably dim lights without actually fitting a dimmer.

    Testing two CU's in one house

    Quite a simple Q really - how would you go about testing an installation where you change the main CU but don't change the 'sub main' powering an extension. Also, I am changing the board to a 17th ed board - does the sub main 'automatically' need upgrading? At the moment it is fed via a 45A MCB...
