Staying Compliant with BS 7671: How Metrel Testers Help Electricians Get It Right First Time
Understanding BS 7671 Compliance
BS 7671, also known as the IET Wiring Regulations, sets the safety standards for electrical installations in the UK. It ensures that installations are designed and tested to prevent electric shock, fire hazards, and system failures. The 18th Edition introduced updates such as:
- Arc Fault Detection Devices (AFDDs) to enhance fire protection
- Surge Protection Requirements to prevent equipment damage
- Changes to RCD Protection to improve safety
- Updated Energy Efficiency Regulations for sustainable electrical design
To comply with BS 7671, electricians must carry out a range of mandatory tests, ensuring that electrical installations meet the latest standards before they are put into service.
