Question

what are the causes of short circuit​

Answer 1

Explanation:

1. Loose Connections

If wire attachments loosen and sag, two wires may encounter each other and create a short circuit. If you notice a hot wire and a neutral wire touching, don’t tighten the wires yourself; you could be severely shocked. Call an electrician to fix the issue for you.

2. Aging & Outdated Wiring

Wires and wire insulation will experience wear and tear over time. The typical lifespan of an electrical system is 30–40 years. If your system is older than this, it may no longer be safe.

If your home was built in the 1970s or earlier, it could still have aluminum wiring. Aluminum wears more quickly and overheats more easily than copper, which puts your home at greater risk for fire. Additionally, older wiring systems weren’t designed to handle the amount of electricity modern homes require.

If your home’s electrical system is getting old, it may be time for an update. Call an electrician you trust to perform an inspection and recommend the best course of action.

3. Faulty Appliance Wiring

Short circuits can occur in appliances by means of a faulty plug, faulty power cord, or a flaw in the appliance itself.

4. Damaged Insulation

Hot and neutral wires are designed with insulation to prevent the two wires from touching and creating a short circuit. Over time, however, this insulation can wear down or become damaged. Be careful that you don’t accidentally puncture electrical wires by placing nail and screw holes in walls. Also watch for evidence of pests chewing through insulation and wiring by checking crawl spaces regularly and repairing any cracks or holes you see throughout your home.

Answer 2

Answer:

reason for short circuit one is overload

Explanation:

• If you plugin too many appliances, and the light suddenly shuts off. What you have created is an Electric circuit overload.

Electric circuits are made of wiring, breaker, and. devices such as light fixture, and they are built to handle a particular amount of electricity.

An electric circuit overload occurs when you draw more electricity from the circuit than what it can safely handle.

• In any Situation in which phase to phase or phase to neutral conductor gets short i.e. comes in contact with each other Short circuit occurs. It may happen due to insulation damage,bad weather conditions,etc.
