Electrical Test and Inspections - Lammart Ltd
NICEIC Periodic Inspections
A full test on the supply of your home/business to BS7671 IEE Wiring Regulations including fuse board, earthing arrangements, wiring, fixtures and fittings (i.e. lights, sockets, switches). Installation methods, loose connections etc.
The following tests are carried out:
- Continuity of earth conductors
- Continuity of ring final conductors
- Polarity
- Installation resistance- to check for any arking or moisture between phase earth
- Earth loop impedance- to verify path of earth
- RCD test to check tripping times and mA settings
The test involves testing circuit at the consumer unit and various points around the property and includes a visual inspection as well as an instrumental test.
The testers used are:
- Voltage tester to measure volts
- Continuity tester to measure ohms
- Insulation resistance to measure Mohms
- Earth loop impendence tester to measure ohms
- RCD tester to measure mS
Also the supplies characteristics are tested to ensure a good earth and path of fault current is present. These tests are called Ze and PSC (Prospective Short Circuit)
The NICEIC inspector who carries out this test enrols to the NICEIC and his work is checked yearly by NICEIC to ensure he works to the BS7671 IEE Regulations
IEE Periodic Inspection
IEE Test to British Standard as above NICEIC test, however, not carried out by an NICEIC engineer. The test is carried out by qualified engineers trained to the 2391 City and Guides IEE 16th Edition and 2391 City and Guides Test and Inspection.
Homebuyers
This check is very useful when buying a house to check if it requires any updating or rewiring prior to purchase. A visual inspection to verify whether the property has current earthing arrangements present and cables are PVC (not rubber/lead), that the consumer units have RCD protection for ground floor sockets (to provide facility for outside use) and has correct overload protection for circuits (i.e. lights 6A not 40A)
PAT (portable Appliance Test)
To check any portable appliances that have 13amp plugs on for insurance purposes and personal safety issues.
This test is required when leaving appliances in rented properties and when appliances are taken into hall of residence or for checking appliances after a flood or fire damage.
Electrical Installation Certificates
This certificate is required by the supply service provider when a property needs reconnection after any period of time. It checks supply and earth conductivity to ensure the supply is safe to connect to.
Emergency lighting
Verification of cell operation on emergency lights required by BS7671, and function test.
Fire Alarm Test
Functions tests on panic buttons, smoke and fire detectors. |
