ECIICESE03 Inspect, test and commission electrical installations

​This standard is about the inspecting, testing and commissioning of electrical installations 

1. ​work safely at all times, complying with health, safety, environmental and other relevant legislation, regulations, guidelines and local rules or procedures
2. ensure that the work environment, material, tools and equipment are suitably prepared for the work activities to be undertaken
3. obtain and interpret the required information and specifications using drawings and other relevant sources
4. plan and agree the schedule for inspecting and testing procedures to minimise plant disruption
5. identify the correct means of electrical isolation or mechanical isolation of any service/supply/plant/equipment in the work area that poses a hazard to safety and carry out isolation and lock-off
6. prove-dead any isolated supplies
7. conduct an initial verification of the installation and complete a schedule of inspections as described within regulations
8. record results on the correct forms

9. prepare to undertake testing activities:

   • visually inspect test equipment for damage
   • ensure you have the correct test equipment in accordance with GS38
   • check the calibration is correct
   • take environmental considerations into account

10. conduct testing in accordance with as described within regulations

    • Dead tests
    • Live tests

11. record test results on the correct form and check against specifications

12. prepare for commissioning
13. commission the installation and check correct operation
14. ensure all commissioning data has been captured and checked against specifications
15. check that the inspection, testing and commissioning is complete and to the required specification
16. follow the required handover procedures
17. ensure the work area is reinstated
18. deal promptly and effectively with problems within your control and report those that have been and cannot be solved

1. ​relevant legislative, regulatory and local requirements or procedures and safe working practices including your responsibilities with regards to reporting lines and procedures
2. preparation and reinstatement requirements in respect of the work area, material, and equipment, and the possible consequences of incorrect actions in these areas
3. relevant engineering drawings, related specifications, quality standards and manufacturers information
4. the difference between inspecting, testing and commissioning
5. safe isolation, lock-off and prove-dead procedures for reasons of safe working
6. techniques for initial verification in accordance with BS7671

7. techniques for testing an electrical installation to include:

   • identification of test parameters
   • selection of appropriate calibrated testing equipment
   • setting up of equipment to predetermined parameters
   • sequence of dead tests
   • sequence of live tests

8. techniques for safely commissioning an electrical installation

9. how to review the data obtained, what types of anomalies may be found and what action to take
10. the documentation used to report inspection, test and commissioning results, their analysis and the importance of correctly recording the results

11. what action(s) should be taken in relation to:

    • the outcome of the analysis
    • relevant procedures and reporting lines

12. your responsibilities for ensuring care and security of tools and equipment used

13. your responsibilities with regard to reporting lines and procedures in your working environment

A Work environment could include:

• engineering construction sites
• controlled operations
• offshore installations
• maintenance sites
• nuclear sites

• repair sites

   A Work environment may be in open or restricted spaces: 

• at height

• confined spaces
• control rooms
• controlled operational and offshore installations
• designated work areas
• potentially explosive atmospheres
• existing plants and structures
• fabrication workshops
• in plant rooms
• inside structures, systems and plant
• on access structures
• on open structures
• onshore and offshore installations
• shafts
• shipyards

• tunnels

   Work area is reinstated could include:

• returning the work area to a safe condition

• removing barriers
• sweeping up
• correctly and ethically disposing of waste materials
• storing re-usable materials, consumables and equipment in accordance with appropriate procedures

• completing all necessary documentation

   Electrical isolation could include:

• getting appropriate authorisation including Permit to Work

• identifying the correct isolations and disconnections required
• correct sequence of isolations and disconnections
• proving-dead of the electrical supply and implications of GS38
• safety methods for maintaining isolations and disconnections

*
*

Mechanical isolation could include:

• getting appropriate authorisation including Permit to Work
• identifying the correct isolations and disconnections required
• correct sequence of isolations and disconnections
• closing a valve or fitting blanks for a service or supply
• checking the mechanical item cannot be moved or move itself
• safety methods for maintaining isolations and disconnections

Cabling systems:

A cabling system is a complete system of cabling and associated hardware, which provides a comprehensive system infrastructure which serves a wide range of uses, such as process control and data or power transmission

Cable containment:

Cable containment systems are used to organise and store cables within a system installation and can include conduit, trunking, ladder, tray and basket systems

Cable segregation:

Power supply and instrument/control cables should be run to prevent electro-magnetic interference

Enclosures:

An electrical enclosure is a cabinet for electrical or electronic equipment and provides protection to equipment users and also protects the contents from the environment

Engineering drawings and related specifications:

An engineering drawing is a type of technical drawing that is used to convey information about an item for construction, maintenance or fault-finding purposes
