Why must electrical work be tested after completion?

The necessity to test electrical work after completion primarily stems from the need to verify that the installation is safe and functions as intended. This is crucial to ensure the safety of both individuals and property. Testing helps identify any issues that could lead to electrical faults, failures, or hazards, such as short circuits or overloads, which could pose risks of fire or electrocution.

Moreover, testing confirms that the installed systems meet the demanded specifications and are performing correctly. When an installation is properly tested, it provides assurance to the installer, the client, and any regulatory bodies that the work complies with the required standards and codes, contributing to overall safety and functionality.

While aesthetic design and cost-effectiveness are important facets of electrical installations, they do not directly impact safety and operational functionality. Additionally, while reporting compliance is a factor, it is not the sole purpose of testing and does not aptly encompass the critical safety aspects. Therefore, the objective of testing aligns closely with ensuring the installation's adherence to safety standards and operational effectiveness.
