    Since there is a small OT regarding switchgears in the topic, I will add three pennies from myself.
    I believe that the times when chap. 2x 18 modules are a thing of the past.


    I would just like to add that the rule that the switchgear can be 2/3 full, and a third of its capacity should be left as a reserve for future expansion has been in force for a long time.

    E, probably not - my last photo "catch" while checking the installation:

    And that's not my fault anymore.
    But I see that the fitter had problems since filling the switchgear ...

    You should also remember about devices that get hot during operation (contactors, overcurrent breakers, etc.). This causes an increase in air temperature in the switchgear and, in extreme cases, may lead to a fire.
    Therefore, not more than 30% of such devices should be placed in the switchgear and spacing between them should be used.

    Both are Moeller's, interestingly I waited for the first one from the right for over a week - it was going all the way from the Czech Republic :)

    Do the regulations really say about securing each socket in the bathroom separately? About the differential for the other circuits ??

    From what I remember, the standards say about RCDs in the bathroom and kitchen.

    I am curious how it is in other European countries? Are they all banging differences for each circuit or only Poles?


    The regulation says that each receiver above 2 KW must be protected with a separate circuit, but the RCD can protect several circuits ... the point is to select the appropriate parameters of the arrester. We, i.e. Poles, function in the SI system, as well as most Europeans, although our standards differ, they seem to be more restrictive :D

    Select the circuits which switching off may cause problems, I have such a circuit for powering computers in the house and control in the boiler room and give them separate protection, so that, for example, a washing machine failure does not turn off your computer or heating at home.

    In other circuits, do not overdo the division into differentials.

    You do for yourself and - as long as you find an electrician to sign it - you can not put any RCD :evil: - but it should each circuit individually or all together. There is no recipe that will ensure your health and life.

Topic summary

The discussion revolves around the optimal number of residual current devices (RCDs) required for a single-family house to ensure safety and convenience. Participants suggest that while having more RCDs can enhance safety, a minimum of three to six differentials is often recommended, depending on the number of circuits and appliances. Key considerations include protecting circuits for lighting, sockets, kitchen appliances, and safety devices like alarms. The necessity of RCDs for circuits in bathrooms and kitchens is emphasized, as well as the importance of not overloading a single RCD with multiple circuits to avoid nuisance tripping. The conversation also touches on the legal standards and best practices for electrical installations in residential settings.
