Three-phase to Single-phase CPL

Hello everyone,

My question is very simple: currently, my setup is three-phase. My powerline adapters are working without any issues. I'm considering switching to single-phase (to save on subscription fees and I don't think three-phase is necessary as I don't have any heavy electrical equipment). Will my powerline adapters still work?

Thank you for your replies.

    Hi,
    certainly, yes.
    It's the opposite that would be problematic.

    Hello,

    Brupala, whom I greet, has responded to you regarding the CPLs.

    I strongly advise you to seek the advice of a professional electrician before switching to single phase. This is not a trivial operation. The main risk is that you may have overloaded lines, particularly the neutrals. The risk is quite significant if your installation was designed for three-phase.
    It's easy to understand: in a three-phase cable, you have 3 phase wires and one neutral wire. If you combine the 3 phases, the return will go through the only neutral wire, which will become overloaded. This is an excellent way to cause a fire.
    So be careful, and consult a professional.

      Hello Pierre,
      this is not the subject of this forum, but anyway changing the electrical distribution board is not within the purview of an individual, and you are right, the power supply to the board must be adapted to the rating of the connection circuit breaker, which will necessarily be changed to switch to single-phase.

        Certainly, it is off-topic, but it is a risky operation. Therefore, a warning is necessary.

        The real problem is not the circuit breaker, but the installation itself. Only an electrician can determine if the existing cables will be overloaded and if they can withstand it.

        The circuit breaker,
        it will necessarily be changed to the same power (or maybe less) in single-phase.
        It's managed by Enedis, like the Linky.
        And the Linky, if it needs to cut off at 30 A, it will cut off at 30 A; many have been caught off guard by Linky devices that cut off before the connection circuit breaker because they were at the limit; it's much more precise, the thing.

    Hello to you,

    hello to Pierr10 and to Brupala.

    I confirm Brupala's response,

    and in support of Pierr10,

    the switch from three-phase to single-phase also depends on the installation you have at home (electric heating, charger for electric cars, large number of rooms, fully electric at home), indeed, in these situations, three-phase allows for the distribution of power,

    if the choice is entirely up to you, ask yourself the right questions; if this idea comes from an electrician or from Enedis services themselves (after a survey), then go for it.

    Edit: Sorry Brupala, I had to respond... the professional side coming back a bit...
