MJ PAT Testing provides testing that is carried out under the IEE’s Code of Practice for In-Service Inspection and Testing.
This testing includes all electrical equipment as detailed in the IEE Code of Practice - this includes fixed equipment (i.e. permanently connected to the supply via a fuse spur), such as hand dryers, towel rails, storage heaters and fans.
MJ PAT Testing uses all the latest testing equipment to give extremely accurate results linked to powerful computer software. All test reporting, results, registers and certificates are emailed directly to the client.
Another benefit of using MJ PAT Testing is that we use test equipment with downloadable software, therefore, we can record all the results on-site digitally, and then download and store all the results securely on a server. This also provides easily retrievable historical data of testing and identify appliances that are ageing and may need attention due to deterioration, as well as supplying copies of data should you need it.
Testing not only applies to electrical equipment with plugs on, but for fixed equipment/appliances (i.e. permanently connected to the supply via a fused spur), such as hand dryers, cookers, panel heaters.
The procedure for testing carried out is briefly explained below
- Appliance will be checked to determine which class it is and tests required.
- The Flex will be inspected for damage to ensure it is free from cuts, fraying or stress.
- The plug will be inspected to confirm it conforms the relevant British Standard, and then for damage. Non moulded plugs will be opened to ensure that the flexible cable is secure and correctly wired.
- All plugs will have their fuse checked to confirm it is of the correct rating for the appliance, is free from any signs of overheating, is in physically good condition and conforms to relevant British Standards.(The fuse check is omitted for plugs of 110V, 230V-16amp and 415V.
- The Appliance will be inspected to ensure that it is in good working order, including ensuring that it switches on and off properly and that there is no damage that could result in access to live parts.
- The environment in which the appliance is being used will also be considered, to determine it is not detrimental to the safety of the user when used.
This involves the Formal Visual Inspection as previously mentioned, followed by the appliance being subject to a series of electrical tests to determine that it is safe to use.
The tests carried out will determined by which class it belongs in and the type of appliance, but whether it is a Class I or Class II, they must provide at least 2 levels of protection.
A few of the tests carried out and why are indicated below:
- Earth continuity Test(for Class I appliances) - This test is to ensure the earth terminal has a low resistance connection to the conductive metal casing of the appliance by electrical bonding.
- Insulation Test - This test involves applying a known test voltage and the resistance measured.
- Protective Conductor Test - This is an alternative test to the insulation test and is used when an insulation test could damage the appliance - and is used primarily for IT and sensitive equipment
- Polarity Test - carried out on extension cables and supply leads, to determine they are correctly wired.
- Functional Test - This test would determine if the appliance functions correctly and its VA rating.
Why Should I have My Equipment Tested?
The simple answer is to provide equipment that is safe to use by the operators in the environment for which they were intended to be used.
This includes any 110V, 230V and 400V electrical equipment used in a designated place of work, or equipment provided for use by the public, whether it has a plug on or not, should be tested to ensure it is safe to use.
The designated place of work does include people who work from home, who use equipment supplied by their employers.
Such equipment may include, but is not limited to: printers, laptop power supplies, mobile phone chargers, in the home office, to main office and factory equipment such as a table lamp, a welding machine, a hand dryer, kettle, heat gun, hair dryer, site lighting, laminator, pillar drills, tyre balancer, arcades and children’s rides.
