Electrical Installation Level 2 Practice Test

The main idea being tested is making sure the installation looks safe and ready before any electrical testing by checking visible, physical aspects. In a new installation, a proper visual inspection covers damage to cables or equipment, fixings being secure, routing that avoids undue stress or sharp bends, terminations that look correct, clear labeling, insulation that appears intact, and presence of test labels showing that checks or tests have been performed. These checks are about what you can see and confirm without energising anything, which helps prevent hazards and ensures the installation is ready for subsequent electrical testing.

The other options belong to different stages. Measuring insulation resistance with a megger is an electrical test that requires equipment and a powered setup, not a visual check. Describing load calculations is a design or planning task, not a physical inspection. Testing the continuity of live circuits under load is a live functional test, not a visual inspection, and would be done only after the system is energised and properly prepared for testing.
