    The "bathroom" standard prohibits connecting devices through plugs in zone I (sockets only in zone III). However, it is possible to power electrical devices permanently in zone I, so an electrician with a little more knowledge (thinking) will remove the cable with a plug and connect the bathtub in accordance with the art and technical knowledge - a separate circuit with a protective conductor and a permanently connected residual current circuit breaker.
    Here is an interesting description of the manufacturer:
    Quote:
    An electrical device, such as a whirlpool tub, can only be connected to the electrical system by an electrician with a current qualification certificate for electrical power installations and electric drive devices with additional authorizations for control and measurement works. For his own safety, the user should ensure that the connection of the whirlpool to the electrical system complies with the following rules:

    - The whirlpool must be connected only to the TN-S network (with a residual current device with a breaking current of up to 30 mA)
    - The electric circuit to which the hot tub is connected cannot supply other electrical devices and should be protected depending on the maximum power consumed.
    - The hot tub can be connected to the installation only through the IP X5 junction box (the distance between the contacts of all poles is not less than 3 mm)
    - Local equipotential bonding of the metal structure of the bath (rack) with the PE protective conductor of the electrical system (earthed) should be made. This connection can only be made with a conductor with a cross-section of min. 4 mm2 Cu (the screw terminal is on the frame near the water pump).
    - The electrical connection point of the whirlpool tub must be measured with the tripping time of the residual current device. A report on the above-mentioned measurement is required as an attachment to the Electrical Connection Certificate.
    It is necessary to equip the fixed installation with means to ensure that the device is disconnected at all poles of the power source, where the distance between the contacts of all poles is not less than 3 mm (if the main power switch option is not used).


    Of course, such a product has the CE mark and is approved for sale (some with a plug) - as safe, but I think that you should consider connecting such a device (stationary) to a socket located in 1 zone. Who installed them there? Maybe it is high time to clarify this point.

    According to the standards and regulations, it is not allowed to install a socket near the bathtub, unless you want to add splendor to the bath with electric shocks :)

    The bathtub should not have a socket, only a sealed box with decent glands to seal the cable entry into the box.

    Write, buddy, something more, what power of the bath [engine], what power network, or you have a differential switch at home, because it may turn out that your bath will need separate protection. There was already a bit on the forum about bathtubs.

    If we do not "knock" him out of his head, he will hurt himself and others even more. Better be aware of the danger - which is high.

    But if the author of a list of posts in which many people more experienced than him expressly express the opinion that he should not try to connect the bathtub himself, maybe the light bulb in his head will "light up" and he will think that maybe there is something in it that the guests are right.

    I would like to recall the first post:

    These issues are regulated by the PN-HD 60364-7-701: 2007 standard. Electrical installations in buildings - Part 7-701: Requirements for special installations or locations - Rooms equipped with a bath or shower.
    It's just that my colleagues who wrote earlier are right. It is the manufacturer and his recommendations, even more stringent power and safety requirements, that take precedence. The standard cannot cover all cases, and the hot tub introduces such cases. Therefore, the electrician who installs the bathtub, has to carefully identify and analyze the issue of earthing, main and local equipotential bonding and other protections.
    This is one of the most difficult things that Kol has mentioned. Bronek22

    I have never connected a hot tub, so I am dark in it for the moment, but I will remind you of the most famous bathtub in Poland, Waserman's bathtub :D it was also badly connected.

    Or maybe Norbert1977 is simply a specialist in another field and on this forum he only asked how it should be connected so that the electrician would not hurt him.
    And here is a bucket of water for the head of the questioning person. Not nice colleagues ....

    If the author has no idea and just wanted to find out, he should clearly write it in the first post ... It is no wonder that his colleagues reacted harshly. Electricity is not a toy, it can hurt you, especially if you have a 230V socket under the bathtub.

    Besides, after the amount of information contained in the first post, you can expect a self-connection attempt.

    It results from our habit of being "experts in everything", because the installations are transformed by tilers, carpenters, bricklayers and other types of professionals who sometimes do not have a clue about the operation of the installation. After all, the current is phase and zero, two wires that need to be pinned with colors, and it will work. When do people start to realize the dangers of this approach to installation, only after someone in the family dies of an electric shock?

    Hello,

    Generally, I have SEP qualifications - although I do not really deal with it, but in school with this specialization I have done and what I can do. However, I have not dealt with this for years when it comes to professional approach to the subject.

    Returning to the main thread: I solved the connection issue like this:
    I just unscrewed the waterproof cover and uninstalled the cord and plug. in its place, I installed a completely new cable (but with the same cross-section of 2.5 ``) by letting it into the wall and in a safe zone, 2 meters away from a closed housing (such as for various lumber, mop, etc.), I connected it to the power cord. Using a can of an appropriate class for this. The power cord will be independently run directly to the switchgear and there connected to the residual current circuit breaker and to the earthing strip.
    One thing I haven't realized is that I don't have equipotential bonding. Generally, I would also have it checked by an electrician who works in it on a daily basis, but knowing from the autopsy, there are many people who practice this profession somewhere "gaining" qualifications and not fully familiar with the subject.

    I am asking for suggestions only if it is enough to connect the power cord to the PE (grounding) strip, which will be connected to the hoop in the future, or if it is still necessary to connect a separate wire to the local equipotential bonding (I will add that I do not have such connections at the moment - home in progress) construction).

    Thank you in advance for your response...
    Please be understanding

    Then write specifically what I did wrong! Your speech did not bring anything to the topic at all. Completely resembles the statement of politicians: "about everything and nothing" is a pity ... because it is supposedly a forum for the exchange of information and not "pouring washing out" on others. I see buddy that you have a lot of points there. Did you get it by apprehending others or did you give any specific advice?

    I am asking other users for specific information. Bronek's friend too - if he has something specific to say ... something that would show that he really knows it and wants to share his knowledge .. unless he just writes to write ..

    Greetings

    I did not write anything like that, and I gave the distance to mount the box ..

    So I don't understand what's the problem?

    Besides, my question concerns: Can Jeszce be connected to the local equalizing connections in the connection I have realized?

    It's necessary to?

    It cannot be done over the internet. A site visit is needed.
    Besides, you have written too little about it. The entirety counts, including distances, RCDs etc. that is, knowledge of the whole issue.
    And from your post it appears that this is a cliché, and you can do whatever you want.

    Buddy, you have a grudge. What is a cooperage outside, because I don't know what's going on. And I think that you yourself are not very familiar with the installation of the object.
    Because there is GSU in the building, other elements, and some hoop outside, what is it and what is it for?
    And finally, the question - what kind of building are you writing about - a single-family house, an apartment on a staircase in a multi-family building. Where is that tub?
    Bronek



    It is a single-family house. As I mentioned it is under construction so there is no GSU / GSW yet. A hoop will be connected to the main earthing box (but this is in the future, so far there is only an internal installation)

    Yes, it's true I don't know 100% - if I did, my post / question wouldn't be here.

    Added after 8 [minutes]:

    Speaking of hoops, definition:

    Cooperage - a tape made of steel, with a flattened rectangle cross-section. 1-5 mm thick, 20 to 85 mm wide, coiled. In construction, it was used in lightning protection systems (as grounding), formerly also as a reinforcement of the Klein ceiling. Anti-corrosion protection: galvanized steel.

    Earthing of the building structure (e.g. reinforced concrete) = earthing of the reinforcement + connection to the external lightning protection system

    The definition of a hoop from Wikipedia ;)

    Bronek, with all due respect, but I haven't learned much from you. I understand that you do not want to share your knowledge with others ... which is a pity ...

Topic summary

The discussion centers on the proper installation of a hot tub power supply, emphasizing safety standards and regulations. It is highlighted that sockets should not be installed near the bathtub due to the risk of electric shock, and instead, a sealed box with appropriate cable entry should be used. The PN-HD 60364-7-701: 2007 standard is referenced, which outlines requirements for electrical installations in wet areas. Participants strongly advise hiring a qualified electrician for installation, as improper connections can lead to serious hazards. The importance of earthing, equipotential bonding, and the use of residual current devices (RCDs) is also stressed, with a consensus that DIY attempts are dangerous without proper knowledge and adherence to safety protocols.
