Quality Management System – ISO 9001:2008

The Institute of Electrical Engineers (IEE) British Standard BS 7671 addresses Requirements for Electrical Installations and dictates that all relevant products must comply with applicable British, International or Harmonized Standards according to the intended installation and application of the equipment. The BS 7671 document is commonly referred to as ‘The Wiring Regulations’.
