Is the original power line with 220V line to do with more than 1 years, has found the oxidation of 150 threadsThere is a LED advertising lamp, 12V., probably 100w. Is the original power line with 220V line to do with more than 1 years, found that the thread has been oxidized. What line of change should I use?The transformer is about 40 meters away from the light. Wrong. It's 10W. Excuse me. Now I want to use the telephone line, OK?
Of course if cable... There is no 100W so much? 12 volt 100W has 8A current Oh before using the yarn diameter much? At least 2.5 square MM diameter oh by the way tell you some threads inside the line is not pure oh. In fact, this also did not pay attention to what the head of online? There should solve the problem of welding on the tin... If ordinary copper can also.
Hello, three electrician, I give you a simple answer, with 4 square cable wear plastic pipe, to improve performance, the best time to add a timer timer switch to avoid every person switch, replace a switching power supply of OK, the total cost is more than and 100 cheaper, the effect is good, very practical. Remember to give me 1093923319qq Chinese stars, thank you. You can use the telephone line, but you must control the distribution box with the power supply. Appliances, if there is a problem, you can provide free of all technology, I professional level.
But the best 100W12V used 4 square MM line...10W12V LED..40M to OK with the cost of the lamp telephone line (core premise is bigger, the best 1 square MM, if too small, the line is not recommended to use slightly. Several calculation, almost 1A current. If the wire diameter is too little load is too large. No matter what, light it should be obvious). But I suggest many dark online head there as a durable tin welding point...
