Periodic Inspections / RCD Testing
Periodic Inspections (PIR) / RCD Testing
“Electrical installations can deteriorate with age and use. It is recommended that electrical installations are inspected and tested periodically as appropriate to their use and environment to verify compliance with the National Rules for Electrical Installations – ET101.”
What is a periodic inspection?
A Periodic Inspection is the testing of the electrical installation in a building from the main incoming power to each final circuit that could include lighting, power and machinery. A Periodic Inspection is an inspection of the condition of an existing electrical installation, to identify any faults or defects that may pose a Health and Safety risk.
The inspection will identify:
- Overloading of circuits
- Fire hazards or potential risk of electric shock
- Areas in need of earthing or earth bonding
Tests will be completed on all circuits over a 5 year period. All results will be logged and recorded on a Periodic Inspection Report which will be submitted to the client on completions. The Periodic Inspection Report will list any remedial works that have been highlighted and any recommendations.
The Registered Electrical Contractor shall use the numbering system (1-4 below) to indicate to the person(s) responsible for the electrical installation the recommended action to be taken:
- Requires urgent attention.
- Requires improvement.
- Requires some attention.
- Does not comply with the current National Rules for Electrical Installations
Where a PIR identifies serious defects in an electrical installation, a Notice of Potential Hazard should also be issued to the person responsible for the electrical installation.
The frequency of periodic inspection and testing shall be determined by the type of installation, its use, the frequency of maintenance and the external influences to which it is subjected.
What is RCD Verification or RCD Testing?
An RCD, or Residual Current Device, is a life-saving device which is designed to prevent you from getting a fatal electric shock if you touch something live, such as a bare wire. It can also provide some protection against electrical fires.
RCD testing and verification should be completed when carrying out a Periodic Inspection on a premises.
