The Visual Inspection - The Most Important Part of PAT Testing

The visual inspection is the single most important part of any PAT test. Studies show that visual inspection alone catches approximately 90 percent of electrical faults.

What Does a Visual Inspection Check?

• The plug: Cracked casing, bent pins, loose connections, correct fuse rating
• The cable: Cuts, fraying, kinks, damage from being trapped or crushed
• The cable entry: Where the cable enters the appliance must be secure
• The casing: Cracks, damage, missing screws, signs of overheating
• Signs of misuse: Taped-up cables, burn marks, unusual modifications

Can I Do Visual Inspections Myself?

Yes. The IET Code of Practice recommends users carry out informal visual checks before each use, and formal visual inspections between PAT tests.

Visual Inspection vs Electronic Testing

Visual inspection catches the obvious faults. Electronic testing catches the hidden ones. Both are necessary for a complete PAT test.
