It is used with the current turned off to determine whether a particular electrical component is carrying electricity and to pinpoint the cause of a problem. On the face of the multitester, a dial or digital setting allows you to set the tool to the type of test you wish to conduct. This test shows the resistance offered by the earthing rods with the connection leads. They also will show: These testers display more information than just pass or fail, including: These readings require interpretation by an electrician or someone with electrical understanding. Some appliances only need a reduced test, called a PAT insulation test. Earth Continuity Test. The test immediately preceding the insulation test should be the earth bond test. Private houses are not covered by this legislation, although occupiers' liability requires householders not to deliberately expose occupants or visitors to unreasonable risks. Example: 64 strand wire with all but one strand connected. The formal term for the process is "in-service inspection & testing of electrical equipment". The three main tests used are the open circuit test, closed circuit test and resistance test. These are crucial safety tools that keep electricians out of harm's way and tell them if there is trouble on a circuit or in a device. Thinking about the type of equipment in use, and how it was used, the HSE looked back at the results from its annual testing of portable appliances across its estate over the last five years. Therefore, it is not a legal requirement to have a PAT inspection sticker or certificate, the obligation is that equipment must be safe. Portable appliance testing (PAT, PAT inspection or redundantly as PAT testing) is the name of a process in the United Kingdom, the Republic of Ireland, New Zealand and Australia by which electrical appliances are routinely checked for safety. Some units can also test Residual-current devices, following the recommendation in the current IEE Code of Practice to test any RCD fitted on an extension lead or multiway adapter. There are two specific extra checks mandated[dubious – discuss] for microwave ovens in the United Kingdom. The first step in any repair or troubleshooting job is to disconnect the appliance from the power source. At the basic level, PAT test instruments carry out basic safety checks. Using a PAT tester under the following conditions; 12V maximum, test current range 100mA to 200mA - commonly known as "earth continuity test" or "screen test", 12V maximum, test current 10A - commonly known as "routine test". Since the testers are designed to test for a wide range of resistance on sophisticated electronic parts, it has multiplier ohm settings, indicated by markings such as X1, X10, XK1, etc., controlled by a dial or buttons. In the UK, there is no requirement to have a formal qualification for persons carrying out PAT Testing. This is best performed by the product manufacturer (if they offer a calibration service) or a laboratory accredited by. Here’s the lid switch for this model: WP8318084 Lid Switch. It may be that a Class I appliance that has all 'unearthed' metalwork could be constructed to Class II standards, and only has the earth connection for functional, rather than protective, purposes. Resistors present a resistance, or impedance, to the electrical circuit and reduce the amount of current that is allowed to flow. The Earth Continuity Test is also known as the Earth Bond Test: This test is carried out only on class 1 appliances. (2-Pack) Appliance Oven Light Bulb,HighTemperature 300 Degree Resistant Incandescent Bulbs - High Temp - 120v 40 watt Clear - 415 Lumens - Medium BrassE26/E27 Base - A15 4.6 out of 5 stars 1,192 $7.99 The purpose of the test is to ensure that the earth terminal has a low resistance connection to the conductive metal casing of the appliance by electrical bonding. PAT testing can be conducted manually, using a collection of standard test gear, including a high-voltage insulation tester and a low resistance ohm meter for earth continuity. PAT150 full functionality PAT tester adds to the offering Portable RCD (PRCDs) testing at 10 mA and 30 mA, separate tests for continuity, insulation, mains powered leakage testing and SELV measurements using the quick test (QT) button, and can be used for testing fixed appliances Battery powered with rechargeable options In Australia and New Zealand, the common name for PAT is simply 'Test and Tag'. e.g. If they do, remove your microwave’s cabinet, locate your door switch, and remove it in order to test it for continuity. Ensuring business continuity and disaster recovery is leading the digital landscape of organizations worldwide as cyber-attacks increase in frequency and sophistication, while ‘work from anywhere’ grows in popularity. Using the results of the previous tests, the HSE decided that further portable appliance tests are not needed within the foreseeable future or at all for certain types of portable equipment. [citation needed] The inspection of the appliances can largely be carried out in-house in many organisations. I replaced the lid switch and it worked perfect! (Note: Only a test voltage flows into the appliance via its mains lead and returns via the test lead.) The 'unearthed' metal is not required to be earthed. Health and safety regulations require that electrical appliances are safe and maintained to prevent harm to workers. [citation needed] In some cases testing was conducted on a three-month (high-risk) and six-month (low-risk) cycle from the early 1960s onwards. In New Zealand it is not a legal requirement to attend a training course however persons undertaking Portable Appliance Testing must be deemed Competent by a Responsible person (being the owner of the premise.
