E.g. it may not be safe to perform a leakage current test which powers up the appliance, such as a grinder, if it can not be secured to a bench; an insulation resistance test may be a safe option. At periodic intervals, the portable appliances are tested to measure that the degree of protection to ensure that it is adequate. At these intervals, a formal visual inspection is carried out and then followed by electrical testing.
These appliances should always be maintained properly and remain in good working order. Fokearn Engineering Ltd services the complete Republic of Ireland, We perform comprehensive electrical safety tests on plug top and fixed wired appliances. We are Safe Electric Registered and our technicians are City & Guilds qualified, we offer a quality PAT Testing services you can trust. As well as the visual inspection, electrical test equipment is used to check the safety of the appliance and the results are documented to minimise future risk factors. The Electricity at Work Regulations 1989 makes it your responsibility to make sure all your electrical equipment is safe to use.

PAT testing is the inspection and testing of the safety of electrical appliances. This is done by a visual inspection that includes looking for frayed cables, damaged insulation, broken plug tops, general damage, and exposed live parts. The Electricity at Work Regulations 1989 require that any electrical equipment that has the potential to cause injury is maintained in a safe condition. However, the Regulations do not specify what needs to be done, by whom or how frequently (ie they don't make inspection or testing of electrical appliances a legal requirement, nor do they make it a legal requirement to undertake this annually). I am looking for the requirements in the United States of America for the in service inspection and testing of portable appliances. In particular the testing required for electrical equipment used on construction sites, such as drills angle grinders and similar.
After successfully passing the MCQ exam you will be eligible to order your certificate of achievement as proof of your new skill. The certificate of achievement is an official credential that confirms that you successfully finished a course with Lead Academy. Certificate can be obtained in PDF version at a cost of £12, and there is an additional fee to obtain a printed copy certificate which is £35.
How frequently should portable appliances be tested?
Many organisations look for employees with CPD requirements, which means, that by doing this course, you would be a potential candidate in your respective field. Because PAT Testing is a regular task, often yearly, it is important to find the right contractor. A good contractor will schedule the testing well in advance and will carry out the work quickly and efficiently as well as providing a quality after-sale service. A calibration certificate should be issued to prove the PAT unit has been electrically tested. Specific microwave leakage testing was recommended for microwave ovens in the United Kingdom up until version 3 of the IET Code of Practice. A current, equal to the rated tripping current, shall be "suddenly" applied between active and protective earth and the operating time measured with maximum trip time 40 ms for Type I and 300 ms for Type II.
Many appliances can be deemed unsafe by simply looking for visual defects like damaged cables and broken casings. Every year thousands of incidents and fatal injuries are reported caused by faulty electrical appliances. These are the simple-to-use and comparatively much cheaper portable appliance testers for most businesses who will test in-house to carry out the testing and suitable for a wide range of businesses. The earth lead is connected to metal parts on both Class I and Class II appliances. For "Class I" during the earth test to prove continuity between earth pin and metal parts on the appliance. For "Class II" during the insulation test to prove the insulation between active-neutral and the metal parts of the appliance.
User checks
They suggest initial intervals for combined inspection and testing that range from three months to one year, and in many cases, longer periods for re-testing . It is strongly recommended that equipment suppliers formally inspect and test the equipment before each hire, in order to ensure it is safe to use. The person hiring the equipment should also take appropriate steps to ensure it remains safe to use throughout the hire period. There is no legal requirement to label equipment that has been inspected or tested, nor is there a requirement to keep records of these activities.
Using 5 times rated tripping current, with trip times reduced accordingly, to simulate high current exposure. In the UK there is no legal instrument that requires a sub-contractor to ensure that all tools and equipment are PAT inspected before bringing onto a site of work. Neither is there any legal instrument which obliges the site owner to ensure third-party equipment is PAT inspected either by themselves or the equipment owner. The correct term for the whole process is "In-service Inspection & Testing of Electrical Equipment" (as defined by IET/IEE and City and Guilds). Only the vacuum cleaner was thought to present a high risk, so the manager decided to get this tested after twelve months and review this after 24 months. The manager kept a note of the checks in her diary to remind herself to re-inspect the equipment.
Formal visual inspections
Most are equipped with an earth continuity test, insulation resistance test and the ability to check the wiring of detachable mains cords. Many do not however include tests which involve applying mains power to the appliance under test, for example, a protective conductor current or touch current tests. The main kind for businesses are simple PASS/FAIL testers that are easy to use, and are aimed at in-house PAT testing with minimal interpretation of results. Advanced PAT testers can give much more information and testing features but are mainly aimed at more highly skilled users. The frequency of portable appliance testing is determined by several factors.
Class III – These are appliances that are supplied at a low voltage called Separated Extra Low Voltage which must be less than 50 V. These appliances are supplied with a transformer supply that is also marked as an SELV PSU. Best Practice is to test the RCD under 1/2, 1X and 5X rated tripping current, each at both the 0 degree and 180 degree phases. (the TEST button referred to here is the test button on the RCD tester not the TEST button on the RCD itself. If the RCD is live, pressing the RCD's own test button should always trip the RCD). The order of the pins of a three pin flat pin plug, to their connections, shall be Earth (radial pin – green/yellow wire), Neutral and then Active , in a clockwise direction, when viewed from the front of the plug looking at the pins. An open-plan office will take less time to test than a building with several offices across multiple floors.
Damaged cords mean the wires inside the cord are exposed, increasing the risk of electric shock and fire. Old and malfunctioning electrical equipment not only takes longer to work, but can be dangerous too. Broadly speaking, anything that is plugged into a power source needs to be tested as part of the PAT testing procedure. Although QLS courses are not subject to Ofqual regulation, they must adhere to an extremely high level that is set and regulated independently across the globe. A course that has been approved by the Quality Licence Scheme simply indicates that it has been examined and evaluated in terms of quality and fulfils the predetermined quality standards. CPD certificates are accepted by thousands of professional bodies and government regulators here in the UK and around the world.
If you're not sure, forward them a copy of your last PAT testing report or asset list if you have one. If you have carried out a risk assessment, this will help you determine how long to leave between tests. If there are any remedial works that need doing when PAT testing, for example, a fuse needs changing or a plug needs replacing, our engineers will carry this work out as part of the procedure. 'Portable appliance testing' is not entirely accurate, as PAT testing also applies to fixed appliances that can't be moved. We've put together a comprehensive guide to PAT testing that will answer your questions. This article will help you understand the meaning of PAT testing, what the PAT testing procedure involves and answer your frequently asked questions about what needs to be tested.
