- In the Philippines, March is considered as the Fire Prevention Month. This is celebrated to raise public awareness on the different causes, effects, and dangers of fire in every household. One of the main causes of fire in the country is faulty electrical wiring. Faulty electrical wiring occurs when your electrical wires are overloaded, slack, or cut along electrical lines. Electrical wiring in houses and buildings includes a circuit breaker a device that protects a circuit from faulty electrical connection. It operates to detect the fault and cuts off the supply of current in case there is a problem in the circuit connection. Without a circuit breaker, nothing will detect circuit breaks that would melt electrical insulation and in worst cases, cause a fire. Too much added load in the circuit may exceed allowable rated circuit load which can cause the circuit breaker to shut off the circuit. Overloading is a common faulty wiring problem that poses hazard to household and building…27. * (a) Write two loop rule equations and one junction rule equation for the circuit in Figure P19.27.
