How many meters long can the power cable in the distribution box be
After calculating (using a voltage drop per unit length suitable for 2. 5 mm² copper cables), you get the maximum length of approximately 30 meters. Article 225 contains the installation requirements for outside branch circuits and feeders run on or between buildings, structures, or poles. You can use conductors 10 AWG or larger for overhead spans up to 50 ft. For spans more than 50 ft, use 8 AWG or larger (unless supported by a messenger wire). Most NM-connectors are approved for securing only one or two cables, but there are connectors listed to handle even more. The configuration shown above, where a cluster of wires enters the top of the box through a single opening, is called a chase nipple. It holds about 21 cubic inches.
