Full Pat Testing
This step involves the PAT test itself over the electrical appliances, using PAT testing equipment.
A highly qualified person can only conduct this step with sufficient training because PAT testing equipment will most likely be used.
During this step, the electrical appliances undergo a PAT test to ensure that their performance stays adequate within the safety parameters.
Different types of PAT testing can be conducted to ensure compliance with PAT testing regulations.
Earth continuity test
A PAT test is recommended for appliances that fall under classification 1. This PAT test ensures that the built-in safety measures on the test equipment work in case of a fault.
This ensures that all safety checks are in place should a fire or spark start. The test also checks whether the current still flows to the circuit. This check is intended to CLASS I applications only.
Substitute Leakage Check
This test measures if the connection travelling from the main appliance down to the cable and outlet is good.
The test is a good measure for identifying whether an appliance receives the minimum nominal voltage to function.
Insulation Test
This test helps in measuring insulation resistance against an electric current. It’s an effective measure of determining if the insulation can resist the current.
This helps prevent any electric shocks and sparks.
Visual and Electrical Safety Check
A visual inspection of the portable appliances needs to be conducted. Most safety defects can be spotted when you undertake visual inspections.
It’s a good way to comply with work equipment regulations and safety without undergoing full-blown PAT testing.
A simple visual inspection helps spot an electrical safety defect, such as burn marks and exposed wiring. Appliances that need to be checked include the following:
*Extension cords
*Hand-held equipment – drills, hair dryers, steam irons, etc.
*IT equipment – fax machines, photocopiers, telephones, etc.
*Multiway adaptors
*Portable appliances
In all cases, the electrical appliances must be turned off, even though it is just a visual inspection.
Another aspect of visual inspection is looking at the conditions where the electrical appliance operates.
Knowing where to put certain types of appliances is part and part and parcel of PAT testing. A few tips to keep your appliance running properly involve the following:
*There are enough ventilation or cooling systems to prevent equipment from overheating
*The equipment must be close to a power supply and avoid overloading extension cords
*There should be no exposed wires or cables that workers can trip on.
Domestic and Industrial Equipment Testing
Conduct Pat Test in home appliance that helps with household chores, including cooking, cleaning, and food preservation. It is also known as a domestic appliance, an electric appliance, or a household appliance. and also industrial equipment that machinery, devices, or containers used to handle, process, or store materials for commercial purposes.
