UL 1278 Figure 8.1 PA130A Probe for Uninsulated Live Parts

UL 1278 Figure 8.1 Uninsulated Live Parts Probe is a specialized safety tool designed exclusively for testing portable electric tools such as drills and grinders. It features a conductive brass probe tip to detect uninsulated live components, essential for verifying if hazardous energized parts remain inaccessible to users. Equipped with an insulating nylon handle to protect testers from electric shock, it applies a precise 10N thrust to simulate accidental contact. Compliant with UL 1278 requirements, it is durable, dimensionally stable, and vital for manufacturers to ensure tool safety and meet U.S. market compliance. Specifications:

• Probe Type: UL 1278 Fig 8.1 Uninsulated Live Parts Probe (for portable electric tools)
• Probe Tip Material: Brass (highly conductive, corrosion-resistant)
• Handle Material: Nylon (insulating, heat-resistant, non-slip)
• Key Dimensions:
  • Probe Tip Diameter: 4.8 mm ± 0.1 mm
  • Effective Probe Length: 63.5 mm ± 0.2 mm
  • Handle Length: 115 mm ± 0.5 mm
  • Total Length: 178.5 mm ± 0.5 mm
• Applied Thrust: 10N ± 0.5N (simulates accidental contact)
• Core Function: Detects accessibility of uninsulated live parts in portable electric tools per UL 1278/60745 standards.

Test Procedures:

• Inspect the probe for any damage.
• Power on the tool and reach normal operating mode.
• Align the brass probe tip with tool openings.
• Apply steady 10N thrust toward potential live parts.
• Check contact with energized components.
• Record safety compliance results.

Applications include safety testing of handheld electric drills and impact drills, and compliance checks for angle grinders and sanders.
