Test Pin according to UL 2200 Figure 8.4

The Test Pin according to UL 2200 Figure 8.4 is a precision safety tool built for stationary engine generator assemblies—such as commercial backup generators and industrial stationary generators. Its slim 3mm conductive metal probe navigates tight gaps (e.g., terminal slots, chassis seams) to check for accessible hazardous live parts, while a 25mm insulating baffle plate prevents over-insertion. Paired with a compact 10mm-diameter insulated handle for precise control, it features a cable-free design (compatible with optional low-voltage test supplies). Applying a controlled 20N thrust to mimic accidental tool contact, it strictly complies with UL 2200, making it essential for manufacturers to prevent electric shock and meet generator safety regulations.

NOTE: Please note SMT-S2962 is without cable. If you want to test with Low-voltage supply with LISUN model SMT-529CV, you may choose SMT-1213C with cables. 

Standards:

Specifications:
Tool Type: Test Pin (UL 2200 Figure 8.4; for hazardous live part testing in stationary engine generator assemblies)
Probe Material: Conductive metal (resistance ≤ 0.1Ω; corrosion-resistant; rigid, no deformation under 20N force)
Handle/Baffle Material: Insulated plastic (handle resistance ≥ 100MΩ; heat-resistant up to 110°C; baffle for over-insertion protection)
Key Dimensions:
– Probe Diameter: 3mm ± 0.05mm
– Probe Length: 15mm ± 0.1mm
– Baffle Plate Diameter: 25mm ± 0.2mm
– Baffle Plate Thickness: 4mm ± 0.05mm
– Handle Diameter: 10mm ± 0.3mm
– Handle Length: 20mm ± 0.2mm
Applied Thrust: 20N ± 2N (simulates accidental small tool contact; aligns with UL 2200 test requirements)
Cable Configuration: Cable-free design (compatible with optional low-voltage test supplies for extended functionality)
Core Function: Detects accessible hazardous live parts in generators via 3mm probe; blocks over-insertion with baffle; ensures UL/IEC compliance

Test Procedures:
1. Inspect the test pin for bent tips, cracked insulation, or loose baffles; confirm conductivity with a test tool.
2. Power on the stationary generator under test (EUT) and set it to normal operating mode.
3. Hold the insulated handle, align the 3mm probe with EUT gaps (terminal slots, chassis seams).
4. Apply steady 20N thrust to advance the probe—stop if the 25mm baffle touches the EUT.
5. Check the connected live-part detector for signals (indicating contact with hazardous parts).
6. Record results: Pass if no contact; Fail if the probe reaches dangerous components.

Applications:
1. Testing terminal slot gaps in commercial backup generators (per UL 2200:2023 Figure 8.4) to block access to live wiring.
2. Verifying chassis seams in industrial stationary generators (compliant with IEC 61032:2017 Figure 9) to prevent contact with internal circuits.
3. Safety checks for generator control box slots (per UL 60335-1:2023) to avoid hazardous part access during operation.
4. Quality control for generator stator terminal covers during manufacturing, ensuring UL 2200 compliance.
5. Post-production testing of portable stationary generator power output gaps to meet global generator safety standards.
