Test Leads BLOW 1738# measurement cables 10 A CAT III 1000 V gray

Measurement test leads BLOW 1738# are designed for electrical measurements with handheld multimeters and similar instruments. These gray test leads support continuous currents up to 10 A and provide insulation rated for up to 1000 V with an overvoltage category of CAT III, making them suitable for many installation and equipment testing tasks. The leads are intended to offer reliable contact and safe handling during troubleshooting, diagnostics and field verification of electrical circuits.

Advantages

These measurement cables combine a compact construction with insulation and current rating appropriate for most commercial and industrial measurement tasks. The CAT III insulation rating and 1000 V limit provide protection for testing within building installations and fixed equipment. The 10 A current capacity allows for measurements where higher currents are present without requiring specialized heavy-duty leads. The neutral gray color helps maintain a professional appearance and makes the leads easy to identify in a toolkit.

Suitable for

• Voltage and continuity checks on building installations and distribution panels
• Current measurements up to 10 A with compatible meters
• Troubleshooting and diagnostics of fixed electrical equipment
• Field testing and verification of circuits within CAT III environments

Key specifications

• Current rating: 10 A continuous
• Insulation voltage rating: 1000 V
• Overvoltage category: CAT III
• Color: gray
• Intended use: multimeter and electrical measurement leads

How to use

Connect the test leads to the appropriate input terminals of a compatible multimeter or measurement instrument, observing correct polarity and meter input selection for the measurement type. Inspect the leads visually before use to ensure the insulation and connectors are intact. Use the leads to probe circuits while observing safe working practices: de-energize circuits when possible, use the correct meter settings for voltage, current or resistance, and keep fingers behind the protective barriers on the probes. After use, store the leads coiled without sharp bends to preserve insulation integrity.

Usage recommendations

For safe operation, use these leads within their specified 10 A and 1000 V ratings and within CAT III environments. Do not exceed the rated current or apply voltages beyond the insulation limit. Replace the leads if any damage to insulation or connectors is visible. When performing high-energy or category IV work, select leads with a higher overvoltage category and follow applicable safety standards and procedures.
