    Hello. I would like to ask how it is with the replacement of fuses in front of the meter. The brother was forced to increase the energy transmission, which is associated with replacing the fuses in front of the meter with larger ones. From what I remember, what is in front of the meter belonged to the ZE, especially since there is a seal and they should replace it, unless something has changed. Maybe I would replace it, but there is no power switch before protection, there is a box outside with 3 BMs. I will only add that according to the contract, the limit is the current terminals at the output from the main protections in the connector, towards the installation of consumers; whatever it means

    I guess this last verse is correct. what is in front of the meter belongs to the supplier and only he can change something there. You should apply to him for an increase in power and he will decide on the application.

    This means that the connector on the outside is owned by the energy supplier, while the rest (except the meter) belongs to the owner of the facility, including the pre-meter protection.
    The replacement of this protection should be performed in accordance with the technical conditions issued by the supplier and it should be done by an appropriately qualified person.

    Not true. Look up.

    In that case, I understand that you have to do it on your own. Notify ZE that you are breaking the seal and replace the fuses. I am just wondering if the electrician will do it under voltage or pull out the BM that are in the box that already belongs to the ZE because there is no other power switch.

    And I wonder if you sometimes try to joke and do it yourself.
    I advise against.

    And what about WTP from ZE are they?
    What is the current connection capacity and what is it to be ultimately?
    What is the current pre-metering (type and value) and what should it be?
    Is the receiving installation adapted to increase the power?

    Don't worry about the BM, the electrician will do the job, or the emergency services will be called to de-energize.

    Ladies, now the live networks are tightening - such tools are available for PPN.
    And you are worried about Esa in exchange.

    He is not afraid for the health of the electrician. Well, unless you are researching how to do it yourself and save a few zlotys. You have to report the unsealing, although in Tauron they are quite loose about it. Unless I came across such a man.

    This must be agreed with the Operator Siecy Dystrybucyjna and the company selling energy. For this purpose, it is necessary to apply for Connection Conditions in connection with the increase in power. The next step is to sign a new contract.

    Without it, energy consumption is inconsistent with the contract and a penalty should be taken into account.
    Electronic meters register when the power is exceeded.

    If the author correctly named Power fuse rather, he is talking about fuse links, knife cartridges.
    Personally, I think that it is easier to replace the insert in the base than "Esa" ;)

    Jake brother wants to connect devices?
    Maybe it is enough to use a soft starter or an inverter?

    It is difficult to advise anything when Autro describes his (brother's) problem so poorly.

    The user cannot take as much from the net as he wants.
    If your neighbor has downloaded as much as he or she likes, you will be in trouble with the voltage value. The distributor keeps an eye on the tension.
    Therefore, it seals the fuses.
    The distributor will be happy to sell energy - provided that the network is efficient.

    Sorry that I did not reply for a long time, but work. The case looks like this:
    My brother set up electric heating in the church. Of course, the appropriate contract with the operator is signed and the conditions correspond to the increase. There were 32A type C fuses on the pre-meter protection, to be 40A. I thought it was up to the operator.
    I thought that there was a power cut-off switch before securing the meter, then I would replace myself at work, I do such things and other electrics, although I am not an electrician by profession. Unfortunately, I did not have the opportunity to replace the BM (Power fuses) and I am not very keen on this, especially since I do not have the appropriate tools (handle)

    As you can see, this is an electrician's job, not a random person.
    As for disconnectors - they are of the RBK type, for example, and you do not need an "iron" for them.

    Work should be performed by an authorized electrician.

    It is also worth asking if the power source would agree to provide a short-circuit protection and a power limiter, eg ETMIAT http://www.jeanmueller.pl/pliki/raniczniki_mocy_etimatt_osp10.pdf.

    Apart from replacing the protections, the switchgear (installation) should be adapted to the new loads (eg cables, strips ("combs"), etc.).

    Finally, the effectiveness of the protection against electric shock should be confirmed with measurements.

    An electrician shouldn't have a problem with that.

    Well, that's what is to be replaced from 32A to 40A

    Probably yes, I am not an electrician, but I have SEP qualifications I have been on the course I passed the exam I needed to do some work just replacing fuses, light bulbs, repairing lighting lamps, etc. But there are just some things I don't do that I'm not an electrician and I can't.

    Inaccuracy either overcurrent circuit breaker or power limiter, you write once differently ....

    I had a case that the operator, after signing a new contract, replaced the circuit breaker with a larger one.

    The power limiter (also called a tariff switch) is not the same device as an installation switch (over-current), eg C32A, commonly known as "SKa". These apparatuses have different tasks and characteristics.

    The ETIMAT T power limiter is designed for installation in a switchgear
    installation as a T pre-meter protection (Fig. 1), which allows for limiting
    contracted capacity consumed by the customer. The purpose of this security is
    selective switching off in relation to overcurrent protection of the consumer Z4.
    The rated current of the ETIMAT T power limiter is selected according to the connected / contracted capacity
    recipient. ETIMATT power limiters in terms of their currents
    rated ones replace selective circuit breakers.

    The ETIMAT T power limiter is devoid of overcurrent circuit breaker
    short-circuit element and has only an overload (thermal) element. Switch
    sealed (blocked access to its current terminals) is installed
    in the switchboard so that its driving lever is accessible to the recipient who
    in the event of an automatic tripping as a result of exceeding the connected load
    or for other reasons, he can attach it himself without calling the plant team
    energy.

    This is a bit of a stretch, because what comes out of it that your brother is a horrifying electric priest.

    Or he is not, and he warms the church by his connection.

    In addition, 40A for heating the church is laughter in the room one 15kW heater for ........ a priest, and where are the faithful?

    The minimum is a 100kW gas heater half an hour before the start.



    In general, it is the faithful who will pay for illegal conscription.
    Seriously, you first report to the supplier that you want to increase power. And you are waiting for the answer.

    The church has a separate connection. It is an old little church there are small radiators mounted, I don't know how much watt they have. I think it must be all right, since there was a guest from the operator and he ordered to replace only these fuses

    This is how you don't read a topic from the beginning.
    The contract for increasing the capacity is signed with the operator.
    Everything is legal. Amen.

    And here I would be most afraid to touch anything without permission and proper full documentation. Perhaps it is still subject to the conservator of monuments? (that's how it is with me and the assembly of anything is a mass of paper, we also installed radiators 2kW 6 pcs)

    All documentation and permits are provided, also by the conservator of monuments. This heating is already working. It was just about increasing the transmission because sometimes the fuses were broken.
    The subject was to answer whose responsibility it is to replace fuses in the pre-meter protection. I would like to thank everyone for realizing that this is the responsibility of the recipient
    I consider the topic to be resolved

    Radiant heaters use energy for the day, a dynamic storage furnace uses less energy. It's worth recalculating. "

Topic summary

The discussion revolves around the process of replacing fuses in front of an energy meter to accommodate increased energy transmission. Participants clarify that the fuses in front of the meter are typically the responsibility of the energy supplier (ZE), and any changes must be coordinated with them. The need for a qualified electrician to perform the replacement is emphasized, as well as the importance of notifying the supplier before breaking any seals. The conversation also touches on the necessity of ensuring that the electrical installation can handle the increased load and that proper documentation and contracts with the energy supplier are in place. The author confirms that the church's heating system is operational and that the responsibility for fuse replacement lies with the energy recipient.
