Why can not I hang a plastic billboard on a post?
Good afternoon, could you please explain why metal shields are hung on poles, isn’t SHCHU 3/1-E UHL1 IP54 an worthy alternative? If I put it and don’t do grounding at the post, will anyone be at a loss? Or maybe it’s not safe with t.z. electrical safety?

Good afternoon! Firstly, it all depends on the requirements of the energy supplying organization. What types of switchboards are allowed to be used in a particular organization - these are installed. Secondly, the type of flap you have given is not suitable for open installation without additional protection, since it has insufficient IP protection. The degree of protection IP54 does not provide adequate protection against moisture.
Incredible, but true: it seems that long rains have come to be regarded as "jets under slight pressure" and ip55 is necessary. Nonsense, of course. A normal Belarusian shield, but it is better to coordinate with the regulatory authorities. Most tin crafts clearly do not reach their applications by ip, especially after a couple of years.
And the grounding at the pole is connected primarily with the separation of the pen, and then with the body of the shield. Again - check with CO.
