Home / Short circuit in low-voltage distribution box
Short-circuit protection is one of the most important design requirements for any distribution box. Machines, their control cabinets and other types of electrical equipment must be designed and dimensioned in accordance with their electrical power supply as well as with the physical environmental and operating conditions prevailing on site. LV distribution boards, part of the electrical distribution system, securely distribute low-voltage power to facility circuits. Its design must account for transformer capacity, available fault current, and the true demand of downstream loads.
