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: There are particular requirements for the use of non-contact devices in coalmines.

Updates regarding the causes of accidents This section has been expanded on to include additional issues that have been raised since the previous publication: Electrical test equipment for use on low voltage electrical systems Date of publication: 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.

For loop impedance, RCD or multifunction testers, the fuse will typically be 10A. For multimeters, fused leads should have a high-breaking capacity fuse hbc or hrc with a current rating that usually should not exceed mA.

If your leads break during testing it can be easy to swap them for another set from a multimeter or clamp meter. A final change regarding test leads relates to the use of fused leads.

The document provides advice and guidance on how to work safely and ensure the right equipment is used and maintained properly. 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.

Such devices should be proved before and after use. This standard, which came into full effect in Mayis the standard that all new two hwe voltage indicators should comply with.

This has a new paragraph added regarding the use of non-contact detectors, or volt sticks: Precautions before testing This section has been expanded upon to recognise additional test processes covered by the guidance note. However, non-contact or proximity devices can be useful in indicating g3s8 something is live, eg when attempting to remove a single cable installed in trunking containing many single cables. If you are unsure as to what test leads you need to use, speak to our technical team on A – switch to normal size A – switch to large size A – switch to larger size.

This includes electrical testing where dead tests are often as effective as live measurements. Risky business Vehicle safety on farms Kidsafe: However, if those leads are not rated to the same category as your installation, you could be putting yourself at risk.

These regular references to CAT safety ratings in the fourth edition of GS38 highlight the importance of ensuring that you have the right equipment and test leads for the job. Other changes include the use of proving units, non-contact voltage detectors and installation category ratings. A footnote has been added to clarify that live working is defined as any testing or fault finding on live systems. This document provides advice and guidance on how to achieve this. 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.

Provided your existing equipment or leads meet either of the above there should be no need to replace anything until they need it. Two key points have been added to the examples of common problems to look for: This section has some nse points regarding correct equipment selection. While it has fundamentally remained the same as the previous version, there are some key additions that could affect the way you test, or the equipment you are using.

Whenever there are changes made to legislation and best practice, questions are often raised regarding existing equipment and whether it can still hde used. An important point raised in the causes of accidents is the use of multimeters.

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.
