- A closed circuit allows current to flow, but an open circuit leaves electrons stranded.
- A switch in the open position disconnects the light bulb from the battery, creating an open circuit.
- Closing the switch completes the conductive path in this flashlight, allowing electrons to flow.
- Avoid using multi-plugs and extension cords.
- Replace all broken & damaged wires of electrical devices and appliances.
- Unplug all the electrical devices & appliances when not in use.
- Must keep a count of the number of devices that are in use in Hot and Cold Weather.

Do MCB need replacing?
Miniature Circuit Breakers (MCBs) are electromechanical devices which are used to protect an electrical circuit from an overcurrent. The lead reasons for an overcurrent could be a short circuit or overload. Unlike a Fuse, MCB does not have to be replaced every time after a fault occurs and it can be reused.
How do I know if my MCB is bad?
How to check a faulty MCB?
How do you know a MCB is faulty?
If any simple load causes the MCB to trip easily, it’s the indication of faulty MCB. There might be numerous reasons behind tripping. But, frequent tripping without any reason or normal load is the indication of faulty switches. You should immediately act and get the MCB replaced.
Can you have a faulty MCB?
The simple answer is that, yes, circuit breakers go bad, so your suspicions may be well-founded. Just like any other essential device in your home (e.g. your water heater, HVAC system, etc.), circuit breakers can quit working properly.
What causes MCB to trip?
The overloading of a circuit is a major reason leading to frequent short-circuit tripping. A circuit breaker trips if it is attempting to draw more power than it is intended to carry.
What causes a MCB to fail?
In most cases, short circuits, spikes, power surges, circuit overloads, and conduit systems with grounded wires are what causes a circuit breaker to go bad. Of course, you should also consider the possibility of the circuit breaker becoming damaged and not working altogether.
