B&K Precision Test Leads 18 AWG 60 V 40 in Black Red

Test Leads for Low-Voltage Measurement

These hook-clip test leads connect a digital multimeter to a circuit using banana plugs on one end and alligator clips on the other. The 18 AWG silicone-insulated wires are rated for 33 V DC and 70 V AC at up to 5 A. Red and black colour coding simplifies polarity identification during bench or field work. The 40 in length suits typical bench distances.

Bench Integration and Clearance

The banana plugs fit standard multimeter input jacks, while the alligator clips grip component leads or test points without soldering. Silicone insulation remains flexible at low temperatures, reducing cable stiffness that can pull on small components. The 40 in reach keeps the meter clear of hot or moving parts in automotive or prototype setups. No external power or adapters are required for basic voltage and continuity checks.

Thermal and Electrical Limits

The leads operate from 0 to 176 °F, so they withstand engine-bay heat and bench soldering environments. Silicone insulation resists melting and cracking better than PVC at the upper end of this range. Rated for 33 V DC and 70 V AC, they are not suited for mains-voltage or high-energy circuits. Current capacity is limited to 5 A, matching typical low-power supply and signal measurements.
