However, non-contact or gs3 devices can be useful in indicating if something is live, eg when attempting to remove a single cable installed in trunking containing many single cables. When it comes to buying new voltage detectors, you can be sure compliance with GS38 if the unit you are buying gse to BS EN When it comes to proving dead this has always been advised against by Electrical Safety First previously the Electrical Safety Council. This is an important safety issue as using equipment that is not correctly rated for the installation category can and has resulted in serious injury and death.

This section has some in-depth points regarding correct equipment selection. Only devices which make contact with the conductor ie not proximity devices should be used for proving dead.

If your leads g38 during testing it can be easy to swap them for another set from a multimeter or clamp meter.

Examination of equipment The changes here are mainly with the wording, however this section does highlight the need to maintain regular checks of test equipment and that these should be carried out by a competent person. Other changes include the use of proving units, non-contact voltage detectors and installation category ratings.

Such devices should be proved before and after use.

Two key points have been added to the examples of common problems to look for: A footnote has been added to clarify that live working is defined as any testing or fault finding on live systems. If you find you have leads or test equipment that no longer meet these requirements, or have been damaged, it would be advisable to replace them to ensure your ongoing safety.

Updates regarding the causes of accidents This section has been expanded on to include additional issues that have been raised since the previous publication: This fourth edition includes current test equipment and references and links to further guidance have been updated.

The Regulations permit few circumstances where it is acceptable for live working activities to be carried out on electrical equipment or systems, this includes electrical testing and fault finding. As a general rule, GS38 states that any equipment or test leads that conform to BS EN or BS EN will meet the requirements and be compliant, provided you have taken into consideration the installation category.

A brief guide Electricity at work: An important point raised in the causes of accidents is the use of multimeters. Trusted by Professionals Search: General changes The guidance note has been amended to reflect the wide range of people who work on electrical systems, particularly those where electrical testing is not a primary activity such as gas installers and alarm installers.
