BS 7671 – Fixed Wire Regulations

What Are Fixed Wire Regulations?

These regulations apply to the design, erection and verification of electrical installations. They also account for additions.

Some existing installations that have been installed in accordance with earlier editions may not be compliant with BS 7671:2018 – this doesn’t mean that they are unsafe or require upgrading but the selection of equipment section has been modified meaning certain usage of uncompliant equipment must be recorded on the appropriate certification. This regulation also means metallic pipes entering the building having an insulating section at the point of entry don’t need to be connected to protective bonding.

BS 7671 also points out within domestic premises additional protection by an RCD with rated residual operating current not exceeding 30mA shall be provided for AC final circuits.

AEL offers Fixed Wire testing as part of a unique testing package covering all regulations to ensure you are safe and insured.

 

Glossary

Additions: All installations will have been altered during their lifetime and this can be anything from a final circuit to consumer unit (DB).

Compliant: When you are compliant with proper certification, you are fully insured for your installation and you know it is safe.

Protective Bonding: This is designed to remove any dangerous failures that can cause a shock by providing an earth fault current.

Certification: Many contractors such as ourselves use NICEIC Certification and provide you with your results and recommendations.

RCD: Residual Current Device, quickly breaks an electrical circuit to prevent serious harm from an ongoing shock.
