    Hello! The circuit breaker can operate either during short circuit or during overload. It may also be malfunctioning simply. Did the problem appear immediately after connecting or after a while? Is the machine very hot? What power heating cable (W / m)? Describe the problem in more detail.

    Cable 16 watts, 90 meters. Knocks out a 16 amp automatic. Thermal protection trips. Why such a heavy load?

      Is it thermal protection that works? That is, he works and knocks out for some time? Is it connected directly to the machine? If so, hot ends or wire? If suddenly the heating cable is connected directly to the machine, although this is unlikely, it may be that the machine overheats from the cable, and it knocks it out.
      What is the wire laid and how long has it been in operation? If it has been used for a long time, there may be a leak somewhere due to damage to the cable, which is why there is an increased current consumption.
      If the cable has only recently been connected, you may have damaged it during installation.

        Thermal protection trips. It works for 5-10 minutes and knocks out the machine. Connected via a cable, 1 meter long, cross section of approximately 2.5 squares. At the end is a fork. The plug is plugged in. From sockets to machines 16A.
        A cable is laid in a pipe with water so that the water does not freeze in the cold.
        Last years, everything was normal.
        We decided to replace it with a new one and problems began. Now I connected a 25 A automatic machine. It does not knock out, but the plug in the socket is heated and the socket heats up. I'm afraid it may catch fire.
        Can you tell me what resistance the cable should be 90 meters?

          Can you measure the current? Maybe when they immersed in the pipe, damaged the insulation and formed a leak?
