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

Welcome & Order of Play 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

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

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

Risk Assessment complete as a group

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

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

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)

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.

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

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

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

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

Any Questions So Far?

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

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

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

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

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

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

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

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

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
