By regulation & rules, safety switches guarding power points and lighting circuits must be fitted in all new households and in office block where electrical circuits are altered or added. This rule was bring together in 1991, so if house was built before this time, it may not be sheltered by safety switches. Safety switches are also essential for power outlets providing cavalcades or similar space in cavalcade parks. When a person makes direct contact with electrical energy, it is directed away from its main path in the electrical circuit and instead goes through the person’s body to earth. A safety switch can sense the change in the electrical circuit and switches the power off in as little as 0.3 seconds. Circuit breakers and fuses protect against short circuits and cur...
