Reliance THP103 Appliance Load Tester

The Reliance THP103 is a digital appliance load tester designed for electricians and technicians who need to verify current and power draw on single-phase circuits. It connects via a 26 in cord and displays readings on an LCD screen. The unit meets cULus standards and carries a CAT safety rating of Not Rated.

Slide-Switch Converts Amps to Watts

A built-in slide switch lets the user change instantly between amperage and wattage modes without swapping leads or navigating menus. The digital display shows the selected value with a current accuracy of +/- 5.00 Percent. The 26 in cord keeps the tester close to the outlet during measurements.

Single-Phase Corded Operation Only

This tester is limited to single-phase, corded-electric supplies and cannot measure three-phase or battery-powered systems. The Not Rated CAT classification means it is not certified for high-energy distribution panels or industrial switchgear. Crest factor is fixed at 3, so highly distorted waveforms may exceed the meter's specified accuracy.

Questions about this item

Will the 26 in cord need replacing after heavy use?

The 26 in cord is a fixed part of the appliance load tester and is not designed for user replacement.

What limits accuracy during sustained testing?

Current accuracy is rated at +/- 5.00 percent, and the crest factor of 3 defines the peak-to-RMS handling limit.

Does the LCD display add noticeable heat or power draw during all-day use?

The unit is electric corded with a digital LCD display; power draw and heat from the screen are minimal compared with the load under test.
