Can a loose wire nut cause a fire? Loose and disconnected wires can become hot enough to start fires or can create serious shock hazards because the breaker doesn't always trip and shut off the power. What causes a power line to catch fire? The most common causes are weather-related events that cause damage to lines and the equipment attached to them.
