What are the reasons for electrical equipment overload

1, electrical equipment specifications are too small, the capacity is less than the actual capacity of the load.

2, the conductor cross-sectional area is selected too fine, the safe current-carrying capacity is less than the load current value.

3, a sudden increase in the load, such as motor with mechanical equipment lack of lubricating oil, wear and tear, the transmission mechanism rolled dead.

4, pulling wires, too much access to parallel loads.
