UL 2200 Figure 8.3 PA140B Probe for Film-coated Wire in Generators

This UL 2200 Figure 8.3 PA140B Probe is a specialized safety tool designed to test the insulation integrity of film-coated wires in generators—including portable, standby, and industrial models. It features a highly conductive brass probe tip to detect tiny cracks, pinholes, or wear in wire coatings (which could lead to electric leakage or short circuits) without damaging intact insulation. Paired with an insulating nylon handle for tester safety, it applies light, controlled pressure to mimic real-world generator operating stress. 

Specifications:
Probe Type: UL 2200 Figure 8.3 PA140B Probe (for film-coated wire insulation testing in generators)
Handle Material: Nylon (fully insulating, heat-resistant up to 110°C; non-slip grip for precise operation in generator housings)
Key Dimensions:
– Total Length: 101.60mm (4 inch)
– Head Diameter: 12.7mm (1/2 inch)
– Former Head Radius: 6.35mm (1/4 inch)
– Tail Diameter: 19.05mm (3/4 inch)

Test Procedures:
1. Inspect the probe (no bent tip, cracked handle, or poor conductivity) and connect it to a wire leakage detection instrument.
2. Power off the generator, open its casing, and access internal film-coated wires—ensure wires are cool and dry.
3. Hold the insulating handle and align the brass probe tip with the wire’s film coating.
4. Glide the probe lightly along the wire’s entire length, focusing on high-vibration areas (e.g., near motor connections).
5. Monitor the detection instrument for signals (indicating coating damage and electric leakage).
6. Record defective wire sections and confirm if the generator meets safety requirements (pass/fail).

Applications:
1. Safety testing of film-coated wires in portable gasoline generators (per UL 2200:2023 Figure 8.3) for outdoor use.
2. Verification of industrial generator motor windings (film-coated wires) for U.S. manufacturing facilities.
3. Quality control for emergency backup generator internal wiring during production.
4. Post-production audits of small portable inverter generators to ensure film-coated wire insulation integrity per UL 2200.
