What risk does unbalanced electrical circuits pose?

Unbalanced electrical circuits pose significant risks, particularly in the context of system overload and failure. When a circuit is unbalanced, it means that the electrical load is not distributed evenly across the conductors. This imbalance can lead to excessive current flow through certain wires, causing them to overheat. As a result, the circuit can become overloaded, which might ultimately lead to system failure as protective devices are overwhelmed and unable to manage the uneven load.

Such situations can damage components connected to the circuit, interrupt power supply, and compromise the overall functionality of the electrical system. Properly balanced circuits ensure that the electrical load is distributed evenly, preventing these hazardous situations and promoting better performance and longevity of the system.
