hello I have TWO line for each air with 4mm cable with 20A BIPOLAR INDIVIDUAL THERMAL AND ANOTHER 2.5MM LINE FOR GRAL USE TAKES WITH 16A BIPOLAR THERMAL ALL GO WITH TWO SINGLE PIPE ONE FOR EACH AIR AND THE OTHER FOR YOU TAKE THE GRAL USE BUT IN A SECTION I HAVE TO TAKE IT OUTSIDE, IT GOES EMBUTIDED UNTIL AN OCTAGONAL CASE AND FROM THAT BOX GOES OUTSIDE WITH A PIPE OF APPROX 1.5MTS UNTIL ANOTHER OCTAGONAL CASE AND AFTER GOES A PIPE FOR EACH AIR THE OTHER FOR THE GRAL USE TAKES. PROVIDE THE VOLTAGE OF THE 220V APROX JACKS UNDER THE THERMAL AND REMAINS WITHOUT LIFTED VOLTAGE AND I HAVE VOLTAGE WITH EACH OF THE AIR THERMALS I DO SAME WITH THOSE OF THE GRAL USE. I WANT EVERYTHING MY CONSULTATION THAT GOES OUTSIDE IN THE OCTAGONAL BOX THAT I HAVE THE THREE LINES MAY BE THAT BY SUPPORTING THE COMMON SEARCH ON THE CABLE WITHOUT PELAR THE LAMP IS ONLY NOT ON ALL THE CABLES ONLY THOSE THAT THE PHASE OR NEUTRAL , ALSO SUPPORTS IN THE OCTAGONAL BOX OF CHAPA TO SEE IF THE SAME HAPPENED AND NOTHING HAPPENS ONLY IN THE CABLES OF THE PHASE BUT I MEASURE IN THE TAKES I HAVE NEGATIVE AND POSITIVE WITH THE SAME LOOKING FOR EVERYTHING IN THE SHORT THERMAL THE MIDO WITH THE 0V TENSION OF LIFT VOLTAGE AND I HAVE 220V APPROX VOLTAGE. WHAT CAN BE.

Mast, good afternoon. As for your query, the same thing happens to my colleague Eldona. It is very confusing and very complicated to understand the plot of the pipe on which some of the power lines travel. It would be important to help you, to draw a simple scheme above all, coloring the wires. On the other hand, I interpret that the external pipe is metal? Junction boxes are too. Regardless of looking for a solution regarding the tension you measure in the cables. It is absolutely essential that the outer pipe and its junction boxes are made of NOMENCLED PVC material. If you send your scheme we can definitely find a solution. Greetings
