Certification
CE Marking
All electrical products within the European Community should be marked with a CE label or stamp. The marking ensures that the equipment meets the requirements of the low voltage and electromagnetic compatibility directives of the EU in UK law.
'X' Suffix
Some equipment will carry a suffix ‘x’ after the certificate number. This denotes ‘special certification conditions’. These details are given on the certificate and on the installation leaflet. The conditions usually relate to cable entry, operation, lamps and maintenance conditions and must be observed by the user.
