Posted by jennycooper on April 4th, 2016

Handling electronics and electrical devices including computer systems during maintenance needs caution. Carelessness could damage your appliances, start a fire or worse still, get yourself or others injured or electrocuted during electrical repairs London. It is for this reason that such tasks be left to a qualified electrical contractor London to keep you safe and to have them running without further complications.

Keen observation of your appliances or research on your electrical gadgets should show you that most electronic systems operate from a DC supply voltage straight from the device’s power supply unit. An AC line voltage of between 240/50 Hz to 120V/Hz in turn powers the supply unit. If you come into contact with such high AC voltage, the voltage establishes a conduction path through your body. The outcome is an AC current flow strong enough to stop the functioning of your heart. It only needs 100mA to trigger a cardiac arrest.

Most electronic device manufacturers install fuses in their products. Such a safety measure, including a circuit breaker does not offer you sufficient protection form electric hazards. Ohm’s research confirms that as resistance decreases, so does current flow increase. He summarizes his findings on this law as V=IR; where V is the potential difference, I is the current flowing through the conductor and R is the amount of resistance of the conductor. The reason why a competent electrical contractor London advice you not to handle electrical gadgets with wet hands is because dry skin leads to a high resistance, while wet skin leads to low resistance which makes you more susceptible to electric shock.

Even then, whether your skin is dry or wet while working with electronics does not guarantee you safety from injury or electric shock. For this reason you should adhere to safety guidelines offer you some handy safety precautions. Before undertaking repair of an appliance, turn off the power supply and unplug the device from this power supply. Ensure that your body and work environment is dry with no traces of pools of water. Additionally, wear insulation gear such as rubber gloves on your hands when carrying out repairs to prevent shock.

If possible, remove all metallic jewellery since metals serve as good conductors of electricity and will expose you to burn injuries in case of exposure to electric current. Such jewellery also conducts electricity and could get you electrically shocked should you touch a live wire while wearing it. Keeping one hand behind your back during electrical repairs London keeps you from forming a loop which conducts electricity in the case of electrocution.

To avoid complications, in the event your computer system needs a new power supply unit, replace the power supply unit with one of a similar power rating. No matter how basic a repair is, novices are advised to keep off as it can be risky and life-threatening.
