Electrical Testing – Safety of Your Installation
Electrical testing is a specialist inspection of the condition of electrical installations in residential, commercial, and industrial buildings. The aim is to ensure user safety and compliance with regulations. The process includes a series of tests carried out by a certified electrician, ending with an official report. This document confirms that the installation is safe, or highlights faults requiring repair.
What Is Electrical Testing?
It is a technical inspection that checks the condition, safety, and compliance of wiring. The electrician tests continuity, insulation resistance, and protective measures. Results are recorded in a formal report. Regular testing prevents fires, shocks, and breakdowns.
Types of Electrical Testing
- Periodic – every 5 years (or more often), to assess existing installations.
- Initial (Acceptance) – when commissioning new or upgraded systems.
- Special – after renovations, faults, accidents, or before property purchase.
Periodic Inspections
The aim is to detect deterioration. Tests include:
- Visual inspection
- Insulation resistance measurement
- Continuity of PE conductors and earthing
- Earth fault loop impedance
- RCD testing
- Earth resistance measurement
Recommended frequency:
- Residential buildings – every 5 years
- Public/industrial facilities – every 1 year
Initial Testing
Performed before use, checking compliance with design and standards. Covers the same tests as periodic inspections, with additional documentation review. The acceptance report is required for building sign-off and utility connection.
Other Situations Requiring Tests
- After system upgrades
