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.
This approach would derate the measuring equipment to the lower rating. 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: If you are unsure as to what test leads you need to use, speak to our technical team on This website uses non-intrusive cookies to improve your user experience.
If your leads break during testing it can be easy to swap them for another set from a multimeter or clamp meter. Whenever there are changes made to legislation and best practice, questions are often raised regarding existing equipment and whether it can still be used. Health and Safety Executive.
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. There are several points highlighted here that should be considered closely when it comes to test equipment selection.
A – switch to normal size A – switch to large size Gs388 – switch to larger size. GS38 Fourth edition Download a free copy. You can visit our cookie privacy page for more information. 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 For multimeters, fused leads should have a high-breaking capacity fuse hbc or hrc with a current rating that usually should not exceed mA.
The Regulations permit few circumstances where it is acceptable for live working activities to be carried out on electrical equipment or systems, hsf includes electrical testing and fault finding.
This document provides advice gz38 guidance on how to achieve this.
Electrical test equipment for use on low voltage electrical systems
Such devices should be proved before and after use. However, non-contact or proximity 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. However, if those leads are not rated to the same category as your installation, you could be putting yourself at risk. Risky business Vehicle safety on farms Kidsafe: 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.
Firstly the Guidance Note has been amended to reflect relevant changes to the standard for two pole voltage indicators, BS EN Other changes include the use of proving units, non-contact voltage detectors and installation category ratings. 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.
Skip to content Skip to navigation. 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. Safe working practices Memorandum of guidance on the Electricity at Work Regulation.
The fourth edition of GS38 makes two important points regarding the purchase of new equipment and the use of older equipment.

A brief guide Electricity at work: We look at the key changes in the fourth edition, the full version of which can be downloaded at the end of this article. General changes The guidance note has been amended to reflect the wide range of people who work on electrical systems, particularly hze where electrical testing is not a primary activity such as gas installers and alarm installers.
HSE aims to reduce work-related death, injury and ill health. A final change regarding test leads relates to the use of fused leads. There are sg38 requirements for the use of non-contact devices in coalmines.

This standard, which came into full effect in Mayis the standard that all new two pole voltage indicators should comply with. Electrical test equipment for use on low voltage electrical systems Date of publication: The guidance has not fundamentally changed from the previous version. Related products Electrical safety and you: This has a new paragraph added regarding the use of non-contact detectors, or volt sticks: 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.
This 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.
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.
