English: Distribution board in Stockholm apartment block. Let's have a look some lacks:
  • 1) Executive diagram is missing. Where from should I know, which circuit breaker protects it? Maybe 250A or even 800A, but it's said nowhere.
  • 2) Probably one RCD (Jordfelsbrytare) protects all the groups (again nowhere said). If it is so - some small leak to the ground (yellow-green wire) and all apartment will stay in full darkness.
  • 3) All groups are protected by C10 circuit breakers:
    • 3.1) if you turn on some small load, while your washing machine working in this line - circuit breaker will trip without any reason;
    • 3.2) as there other fuse boxes are missing, "C" is not suitable characteristic to circuit breakers for using in the living area;
    • 3.3) chandeliers and other light fixtures could have more thin cable, than 1.00mm² of copper, so 10A circuit breaker might be too big to protect those weak knots.
  • 4) Electricity meter is somewhere outside of distribution board, so energy company can cheat their consumers easily.
  • Remind - to do this works officially in Sweden, you should have lot of useless papers (or work in someone's company, which has heap of those papers). Even academic degree is required to strip the wire and clamp it in terminal. Marasmus under the higher category.
  • My rate to this work: done by qualified laymans, which followed minimal requirements only to be correct.
  • Correct way:
    • B13 to outlets (each group)
    • B4 to lighting (each group)
    • C1 or C0.5 to modem and TV amplifier (each group)
but access there is sealed, so lacks couldn't be corrected at all.
