A footnote has been added to clarify that live working is defined as any testing or fault finding on live systems. When it comes to proving dead this has always been advised against by Electrical Safety First previously the Electrical Safety Council.
This section has some in-depth points regarding correct bs38 selection. 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.
HSE aims to reduce work-related death, injury and ill health. A newly added paragraph touches on the importance or carrying out risk assessments, putting into place relevant safety measures and the use of appropriate PPE. 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.

Trusted by Professionals Search: If you are ts38 as to what test leads you need to she, speak to our technical team on This includes electrical testing where dead tests are often as effective as live measurements.
This standard, which came into full effect in Ts38nse the standard that all new two pole voltage indicators should comply with. 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.
GS38 Fourth jse Download a free copy. The Electricity at Work Regulations require those in control of all or part of an electrical system to ensure it is safe to use and maintained in a safe condition.
There are several points highlighted here that should be considered closely when it comes to test equipment selection. Provided your existing equipment or leads meet either of the above there should be no need to replace anything until they need it.
Electrical test equipment for use on low voltage electrical systems
This has changed in the fourth edition, emphasising the importance of using test leads and test equipment that is suitable for the category of the installation. Hee should be done preferably on a voltage proving unit some devices have built-in proving units or otherwise on a known live source of similar voltage to the circuit under test providing precautions are taken to prevent danger arising.
However, if those leads are not rated to gx38 same category as your installation, you could be putting yourself at risk. There are particular requirements for the use of non-contact devices in coalmines.
Clarification of the different installation categories BS EN CAT ratings is included in the guidance note as a reference and a visual guide is available to download at the end of this article. A final change regarding test leads relates to the use of fused leads. This has a new paragraph added regarding the use of non-contact detectors, or volt sticks: For loop impedance, RCD or multifunction testers, the fuse will typically be 10A. The fourth edition of GS38 makes two important points regarding the purchase of new equipment and the use of older equipment.
When it comes to buying new voltage detectors, you can be sure compliance with GS38 if the unit you are buying complies to BS EN Electrical test equipment for use on low voltage electrical systems Date of publication: For existing leads and equipment predating these standards, or manufactured to a different standard, GS38 states they must be maintained to prevent danger and should comply with the guidance probes and clips in paragraph 9 download the full guidance note below.
Throughout this section, revisions have been made to include the need for ongoing risk assessments to ensure safety is maintained as well as re-emphasis of the need for selecting the right CAT safety rating for the installation under test. Setting the multimeter to the wrong voltage range will lead to a false reading, but having it set to measure current or resistance can result in excessive current being drawn through the test probes, leads and multimeter.
Precautions before testing This section has been expanded upon to recognise additional test processes covered by the guidance note. Related products Electrical safety and you: This document provides advice and guidance on how to achieve this.
Hse guidance note gs38:
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.
However, non-contact or she 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.
Specific requirements for test leads In line with changes made to the standards that cover the manufacture of test leads, there are some specific requirements that leads should comply with added in the fourth edition: For multimeters, fused leads should have a high-breaking capacity fuse hbc or hrc with a current rating that usually should not exceed mA.
Such devices should be proved before and after use. Updates regarding the causes of hwe This section has been expanded on to include additional issues that have been raised since the previous publication: The document provides advice and guidance on how to work safely and ensure the right equipment is hxe and maintained properly.

Firstly the Guidance Note has been amended to reflect relevant changes to the standard for two pole voltage indicators, BS EN If your leads break during testing it can be easy to swap them for another set from a multimeter or clamp meter.
An important point raised in the causes of accidents is the use of multimeters. A brief guide Electricity at work: Safe working practices Memorandum of guidance on the Electricity at Work Regulation.
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 approach would derate the measuring equipment to the lower rating.

A – switch to normal size A – switch to large size A – switch to larger size.
Whenever there are changes made to legislation and best practice, questions are often raised regarding existing equipment and whether it can still be used. The guidance has not gss38 changed from the previous version. 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.
