Electrical systems installed anywhere have the potential to cause severe burns or electrocution causing death. Fires are devastating for a listener too. Do not try to fix any panel if you are not sure how to. Call a service electrician to help you. DIY fixes only cause more chances of adverse effects. Regular maintenance of the electrical system creates a cautious environment, as well as your pieces of equipment, run smoothly. Maintained HVAC, outdoor lighting, your meter box etc must be checked frequently. Use extensions that do not cause voltage drip at home. And most importantly put covers on the plugholes so that kids do not put their fingers inside them. Hence, keeping electrical safety at home is crucial especially if you have little ones roaming around.
