This European standard EN 50628 specifies the safety requirements for the erection of electrical installations.This European standard EN 50628 specifies the safety requirements for the erection of electrical installations.EN 60079-14 standard gives the specific requirements for design, selection and erection of electrical installations in explosive atmospheres.NOTE 1 EN 60079-14 standard can apply to electrical installations in mines where explosive gas atmospheres other than firedamp can be formed and to electrical installations in the surface installation of mines.NOTE 2 For next edition of EN6079-14 installation requirements for mining equipment might be implemented.This standard applies toa)Electrical installation in underground workings of mines.b) Electrical installations and parts of electrical installation above ground, which are directly connected with the underground workings in functional and safety relating matters because of being part of the underground working process. These are in particular" Safety and monitoring devices relating to the power distribution of the underground workings," Telecommunication installation of hoisting and inclined haulage plants," Intrinsically safe electrical installations of above ground installation being part of underground workings," Remote control systems if they have to fulfil increased requirements relating to functional safety," Electrical installation and electrical equipment of ventilation systems and shaft casings above ground being endangered by methane of the underground ventilation," Methane drainage systems.c)Electrical installation in underground workings outside mining if it is demanded of the competent national authorities.National regulations of the mining authority shall remain unaffected.This standard applies to installations at all voltages mentioned in Clause 10.Requirements above both columns are requirements of all underground workings.
