A surge protector also known as a surge suppressor or surge arrester is a device designed to protect electrical and electronic devices from voltage spikes or surges. While BS 7671 primarily focuses on wiring regulations surge protection is a crucial aspect of electrical safety. Here is detailed information on surge protectors:
Functionality:
A surge protector works by diverting excess voltage away from connected devices. It detects voltage spikes and redirects the excess energy to the ground preventing damage to sensitive electronics.
Installation:
BS 7671 doesn't specifically detail the installation of surge protectors as it primarily addresses wiring regulations. However surge protectors are typically installed at the electrical panel or as individual devices at points of use to protect specific equipment.
Types of Surge Protectors:
Testing and Maintenance:
Surge protectors should be tested regularly to ensure they are functioning correctly. Some models come with indicator lights to signal if protection is active. Regular maintenance involves replacing surge protectors if they have absorbed a significant surge.
Compliance with Standards:
Surge protectors should comply with relevant safety and performance standards such as those provided by organizations like UL (Underwriters Laboratories) or IEC (International Electrotechnical Commission).
Application Considerations:
Consider the specific needs of the electrical system and the types of equipment to be protected when selecting surge protectors. Different devices may require different levels of protection.
Role in Electrical Safety:
Surge protectors play a critical role in preventing damage to electronic devices and equipment caused by voltage surges. While not directly addressed in BS 7671 their use is widely recommended for comprehensive electrical protection.
While surge protectors are not explicitly covered by BS 7671 their importance in protecting electronic equipment from voltage spikes is widely recognized in electrical safety practices.
