Snap-on TESI5LC Torque Wrench, N·m Light Signal Torqometer, 1/4″ Drive, 5 N·m, with Calibration Certificate

Description

Loose terminal screws cause many hot spots in control panels and switchboards. The Snap-on TESI5LC torque wrench helps panel builders tighten those screws to the maker’s figure. It reads in newton meters, and a lamp flashes when the pull reaches the preset value. A calibration certificate is part of the listing, according to its source name.

Why panel shops use the Snap-on TESI5LC torque wrench

A wiring technician may tighten hundreds of terminals in one cabinet. Hand feel drifts over a long shift, and the drift is hard to see. A light at the target gives the same cue on the first screw and the last. As a result, QA staff spend less time redoing joints at the final check.

Base model figures

These numbers come from Snap-on’s newton meter table for the TESI5L. That table says the C suffix orders the version with a certificate of calibration, which matches the TESI5LC code.

Terminal work for the TESI5LC

• Clamp screws on miniature and molded case breakers.
• Terminal block screws on control and field wiring.
• Contactor, relay and overload terminals in motor starters.
• Ground bar screws and small cable lug screws.

Check each device’s data sheet, because terminal torques differ by size and brand. Then set the TESI5LC to that figure before the shift.

Accuracy grade on a small scale

Lost in HCM lists the TESI5LC under Newton Meter Reading/Standard 2% Accuracy. Snap-on defines that grade from 20% of full scale upward, which is 1 N·m on this dial. So terminals below that point need a torque screwdriver instead. In addition, record the certificate number on your panel test sheet.

Bench care for the Snap-on TESI5LC torque wrench

Panel shops are clean, yet small tools still get dropped from benches. Keep the wrench in its case when you are not using it. Also test the lamp and look at the zero before each cabinet. Never use it to back out a stuck screw. Finally, recalibrate it on the cycle your quality plan sets.

Panel builder questions on the TESI5LC

How do I fit a screwdriver bit?

The base TESI5L has a 1/4-inch square drive. So use a 1/4-inch square bit holder that suits your terminal screws.

Is 5 N·m enough for busbar bolts?

Usually not. Busbar joints often need far more torque, so pair the TESI5LC with a larger wrench for those.

Does it come with a certificate?

Yes. Its source name includes a calibration certificate, and Lost in HCM can explain what that document records.
