Disconnect, secure, verify dead, earth and short-circuit, protect against adjacent live parts: what the five safety rules mean on site, with a checklist and the reconnection sequence.
Read more
A wrist-worn proximity alarm senses the electric field of a live conductor and warns the wearer. How it works, its limits, choosing HXW-6W or HXW-6WL, and a daily site routine.
Read more
A proximity alarm is a personal warning device that sounds when you get dangerously close to a live conductor. We explain the differences between wrist, arm and helmet models and how to choose.

Choosing the right voltage detector depends on system voltage, working distance and site conditions. This guide walks you through the selection criteria step by step.

Phase checks are vital when commissioning a new installation or paralleling two supplies. We summarise how low-voltage and medium/high-voltage phase testers work and how to use them.
Read more
From pen-type non-contact detectors to hot stick high-voltage detectors and fixed voltage indicators, each technology meets a different need. We explain which one to choose and when.
Read more
A de-energised line is not safe until it has been earthed. We summarise how to choose the right earthing set and the correct order in which to apply it.
Read more
AC and DC catenary, third-rail and monorail systems each need different voltage testing equipment. We summarise the safe working steps and how to choose equipment for railway electrification maintenance.
Read more
De-energised cables, capacitors and equipment under test can store a dangerous charge. We explain what a discharge stick does, the main types and how to use one correctly.
Read more
A faulty voltage detector can show a live line as dead. We explain why a pre-use check and regular testing are essential.
Read more
From voltage detectors to earthing sets, and from proximity alarms to discharge sticks: the core safety equipment every electrical maintenance team should carry, as a checklist.
