  1. Brandon Portable Appliance Testing & R.C.D. Training The benefits, frequency and procedure for electrical safety testing

  2. Hello / Emergency procedure Distractions Resources – Portable appliance tester, desk space, pens, class1 & class 2 power tools Why are we here? Risk assessment Why PAT test? Class 1 & Class 2 Visual inspection Which test for which appliance? Load testing Record Keeping Questions & Answers Fault simulating Practical – Lets get testing R.C.D. testing Welcome & Order of Play

  3. Lets Get Started • Distractions – phones off, radio’s, loud people and machinery at a distance • Resources – We will need: • A space / desk area for writing • Portable Appliance Tester • Class 1 & class 2 power tools • Lunch / break arrangements / times agreed • Risk Assessment – completed together

  4. Why are we here? • All electrical equipment that we hire out could be potentially fatal • This course is aimed to help you understand why all electrical equipment should be P.A.T. tested • How different equipment should be PAT tested • The safety of yourself and our customers

  5. Risk Assessment complete as a group

  6. Why P.A.T. test? • P.A.T. testing is a legal requirement as all equipment in the work place must be suitable and safe. • All equipment should be tested at least every 12 months • In the hire industry it is every 9 months, after every hire or repair • 9 month shelf life • 3 months hire life • Electrical test tickets

  7. Class 1 & Class 2 equipment • Class 1 – Earthed appliance • Class 2 – Double insulated • Differences and how to tell • Data plates / Class symbols • Wired to machines with an earth point • Manufactures specification

  8. Visual inspection • Plug • Body – General damage, British standard • 240v 13 amp – BS1363A – Hire • BS1363 – Domestic • 110v, 240v & 415v 16,32 & 64 amp – BS4343 • Or CE mark ( European standard)

  9. Visual inspection • Plug Pins • Pin insulation, missing / broken, burnt / pitted, pin configuration, bent, loose • Fuse • 500watts or 2.2amps – Machine higher rated than this, requires 13amp fuse, below this requires 3amp fuse. May come across 5amp fuses • No foil, solder,nails etc.

  10. Visual inspection • Wiring • How to wire a plug, general condition, copper exposed • Cable clamp • Length of access wire • Bare wires

  11. Visual inspection • Cable • General damage – cuts, splits, burns, twisting, concrete, mud NO electrical tape • New cable – Size, length, core, colour, type ( arctic / rubber ) • Arctic is plastic, ideal for cold conditions. Rubber is heat tested to 650v. • Black – Power tools • Yellow – 110v Extensions, Splitter boxes, Lights

  12. Visual inspection • Cable • Blue 240v – Extensions, Splitter boxes, Lights, Transformers and R.C.D.s • White 240v – Domestic white goods • Orange 240v – Gardening equipment • Wiring code tape – also a legal requirement

  13. Visual inspection • Machine casing • General damage – Housing, Cable guard, Trigger etc • Missing or incorrect parts – Nuts, bolts, screws, rubber sleeves, levers, handles • Safety labels / data plates

  14. Any Questions So Far?

  15. Which test for which appliance? • TEST ‘A’ • Class 1 machine, Non motor machine, Cable less than 5 meters e.g. – Wallpaper stripper • Earth test – No more than 0.1 Ohms • Insulation test – More than 2 mega Ohms • Flash test – 1250 volts

  16. Which test for which appliance? • TEST ‘B’ • Class 1 machine, Non motor machine, Cable more than 5 meters • e.g. – Extension lead • Earth test – No more than 0.5 Ohms • Insulation test – More than 2 mega Ohms • Flash test – 1250 volts

  17. Which test for which appliance? • TEST ‘C’ • Class 1 machine, Motorised machine, Cable less than 5 meters • e.g. – Floor sander • Earth test – No more than 0.5 Ohms • Insulation test – More than 2 mega Ohms • Flash test – 500 volts

  18. Which test for which appliance? • TEST ‘D’ • All Class 2 machines • e.g. – Breaker • No earth test • Insulation test – More than 7mega Ohms • Flash test – 3000 volts

  19. Which test for which appliance? • LOAD TEST • Tests the running condition of machines • Pass below / fail above data plate rating • 10% lenience either way • Watts – Amps – KVA • 1 KVA = 1000 watts • Watts divide Volts = Amps e.g. 2400w divide 240v = 10 amps • Volts x Amps = Watts e.g. 2amps x 110v = 220w • W • V A

  20. Record Keeping • Filling in test logs • Keep our test logs for Seven years • New test log each day • Each tester has own test log • File in date order

  21. Fault simulating • Simulate a fault each day before any testing commences • Log the result of this each day on the electrical test log sheets • Demonstrate fault simulator

  22. Lets get testing • Demonstrate the various tests on that particular model of tester • Practical session each candidate test a class 1 and class 2 piece of equipment • Start with visual checks • Finish with working out load rating and load testing

  23. RCD testing • Don’t forget RCD’s require PAT testing – which test? • Table of testing • Six tests should be done every time • Log results on electrical test log sheets • Don’t just tick boxes

  24. Review • 10 questions • No pass / fail • Thanks for your time • Brandon people feedback
