EUCE.png

This article refers to CE versions of products, with a focus on UK PAT testing regulations

This article is intended as a guide for a suitably skilled electrician to perform regular electrical inspection and testing on portable ETC equipment.

Any advice and values given here should be confirmed with a suitably skilled, trained and experienced electrician.

 

Source 4 luminaire (Incandescent)
  • Visual inspection
    • Ensure the plug is region appropriate (UK would be BS EN 60309-2 or BS 1363 or BS 546)
    • Ensure the plug terminals are secure
    • Ensure the cable assembly is free from damage
