Short circuit between live wire and ground wire in the distribution box
In this short circuit, a live wire connects to a grounded part of the box or devices, the ground wire, the outlet, or other components. Between the primary wire and ground wire, I have 5 kΩ - which I know is very very low (should be infinite) but still not enough to create a shortcut. A ground fault occurs when electrical current unintentionally flows from a live wire to the ground (earth). Ground or earth provides a common return path for electric current in an electric circuit. The two most common reasons for a circuit breaker to trip in case of a fault are short circuits and ground faults.

The circuit breaker in the household electrical distribution box burned out
If you suspect your circuit breaker has burned out, turn off the power to the affected circuit and contact a qualified electrician immediately. A burned circuit breaker is a big problem that should be addressed as early as possible before it gets worse. It automatically interrupts the circuit when it detects an abnormal condition, preventing potential hazards such as fires or equipment damage. Common causes include loose connections at the switch, internal wear and tear, excessive electrical loads, over-torqued terminals, and short circuits.

Standards for Electrical Equipment Boxes and Distribution Boxes
The standard DIN EN 60670-1, VDE 0606-1 applies to boxes, enclosures and parts of enclosures for electrical installation equipment with a rated voltage not exceeding 1000 V AC and 1500 V DC intended for domestic and similar fixed electrical installations indoors or outdoors. You must make safety your top priority when working with low voltage distribution boxes. The Group's environmental commitment is centred on 3 guiding lines: taking on board environmental management in the running of its industrial sites, reducing the environmental impact of its products by eco-design, providing environmentally friendly solutions that contribute to energy savings. The IEC Standard for Power Distribution Board Design and Layout serves as the global benchmark for ensuring safety, efficiency, and reliability in electrical systems.
