| Abstract |
This leaflet is aimed at owners and operators of electrical switchgear inindustrial and commercial organisations who have little knowledge and expertise available in-house on electrical matters. It summarises the comprehensive advice given in the HSE guide 'Keeping electrical switchgear safe,' which is aimed at organisations employing electrical engineering managers and specialists. The leaflet provides guidance on the managing of three-phase electrical switchgear with voltage ratings from 400-33 000 volts alternating current(ac). It covers selection, use, care and maintenance. The equipment covered includes switchgear using oil, air, sulphur hexafluoride or vacuum as the interrupting medium. The leaflet deals with circuit-breakers, switches,switch fuses and isolators and also covers contactors operating at voltages above 1000 volts alternating current (ac). It does not cover direct current(dc) switchgear, low-voltage switchgear (voltages up to 1000 volts ac) and switchgear used on single-phase alternating current (ac) traction systems. The advice contained in the leaflet will help you to keep your electrical switchgear safe and comply with The Health and Safety at Work etc Act 1974, the Management of Health and Safety at Work Regulations 1999 and the Electricity at Work Regulations 1989. Contents: Introduction; Managing switchgear; Policies and procedures; Inspecting and maintaining switchgear; Selecting, replacement or refurbished switchgear; Measures to limit fires; Further reading; Further information; other sources of advice. This leaflet contains notes on good practice which are not compulsory but which you may find helpful in considering what you need to do. |
