Can I split the cable inside the distribution trough

The only difference between a distribution slot and a wire tube is that one can be opened and the other cannot. Usually, the wire tube cannot be separated because it cannot be opened. Once there is a problem at the branch line, it is very difficult to fix! The wiring slot is different and you can open the lid, which is good for maintenance! Therefore, the line can be divided! What is the current capacity of the actual line? If it were a traditional point, a square line with a copper core wire would have about 5 currents! But it's better not to. If there is a problem in the branch, inspection and maintenance will not be convenient.

Cable negative load flow is an unanswerable question! It is not only related to the cable material, but also to the office environment (empty or threaded pipe, the number of cables in the pipe through the pipe, single-phase or three-phase electricity). In order to ensure load operation, the design scheme of electric power enterprises is 0.5~0.8KW output power (2.5~4A) for 1 square wire copper wire, and 0.8KW design scheme is generally adopted. The pipe groove cannot be divided into pipelines, and the wiring groove can be divided into wiring groove, and the wiring groove cover can be opened and closed. The large load flow of the cable depends on many factors, such as load conditions, main use, laying standards, office environment and so on. In general, the load flow rate of copper wire safety cable is 4-6A per square meter.
