Klein Digital Clamp Meter Electrical Maintenance and GFCI Tester Set

Klein Tools CL120 Clamp Meter Electrical Test Kit (CL120KIT)

Diagnose, balance, and commission roof de-icing and heat trace circuits with confidence using the Klein Tools CL120 Clamp Meter Electrical Test Kit. Designed specifically for electricians and heat cable installers, this all-in-one diagnostic kit pairs the CL120 400A Auto-Ranging Digital Clamp Meter with the RT210 GFCI Receptacle Tester and the 69409 10x Line Splitter, giving you everything needed to verify cold-lead current draw, validate panel branch loads, and troubleshoot dedicated outdoor ground-fault protection circuits.

Self-regulating heat cables experience high initial inrush current upon cold startup. With the included 10x line splitter and auto-ranging clamp jaw, you can safely measure operating amperage directly from cord-and-plug connections without cutting or modifying power leads. Complete with a rugged carrying case and test leads, this kit ensures your heat trace systems are operating within safe branch capacity and properly protected against ground faults before freezing weather hits.

Highlights for Heat Cable & De-Icing Installations

• Accurate Heat Cable Amperage Verification: Measure AC current up to 400A through the clamp jaws to monitor steady-state power draw, verify branch circuit loading, and track high-inrush startup surges on self-regulating heat trace runs.

• Safe In-Line Current Testing (69409 Line Splitter): Test plug-in 120V de-icing controllers and pre-assembled heating cables up to 15A without stripping jackets or separating conductors. Built-in 10x multiplier window enables precise current readings on low-draw cable runs.

• Code-Mandated GFCI Diagnostics (RT210): Instantly test and confirm 30mA equipment protection or standard GFCI breaker/receptacle tripping function, identifying common wiring issues like open neutral, reverse polarity, and missing ground paths.

• Full Circuit Multi-Meter Functions: Measures AC/DC voltage up to 600V, continuity, and resistance via heavy-duty test leads to confirm clean supply voltage at the power connection kit before energizing.

• High-Visibility Backlit Display: Backlit reverse-contrast LCD screen ensures effortless viewing in dark mechanical rooms, dim crawlspaces, and overcast rooftop conditions.

• Jobsite-Grade Safety & Reliability: Built with double insulation and rated CAT III 600V, Class 2 for safe diagnostics around outdoor junction boxes and distribution panels.
