Serbia acquires high and low voltage distribution boxes
In line with its regional growth strategy, on July 16, 2025, MVM Zrt. signed a share purchase agreement with the Serbian Maneks Group to increase its stake in Energotehnika Južna Bačka and Elektromontaža Kraljevo from 33. Schneider Electric, the leader in the digital transformation of energy management and automation, has signed a contract to supply medium voltage (MV) equipment and grid management software to upgrade Serbia's electrical distribution network. Record deployment of renewables, accelerating e-mobility diffusion, exponential demand expansion in data centres, hydrogen pilots moving toward industrial scale, and the pressing need to reinforce ageing transmission and distribution infrastructure are converging into one structural reality: Europe. It will also reduce network losses, which will allow huge CO2 emissions reduction and savings.

Primary distribution boxes should not have cross-wiring
Follow key principles: no cross-level wiring, one machine-one switch, ≤30m box spacing, dry/ventilated installation for safe distribution. Correct wiring methods for circuit breakers within distribution boxes are fundamental to ensuring electrical safety and compliance with established codes. Each switch box shall connect to and control only one associated piece of electrical equipment (including sockets). Select a well-ventilated and dry place to avoid poor heat dissipation causing equipment. You need to consider where it will be used, how much power it needs to handle, and how well it's built to last. Supply is TNCS, no measurements at this stage The supply head is in an external meter box, I will be putting an additional box of some sort next to it.
