How hot is too hot? Many of us run our hands over the breakers anytime we are dealing with a breaker box just to see if any of them are hot. The thermometer will tell you an exact temperature that you can make a judgement on instead of taking a SWAG.
Also great for checking motors that seem to be too hot. If you don't take a measurement, you don't know. After all, a 30 degree C rise above ambient is plenty toasty & you might think it is too hot since you'll barely be able to touch the motor.
Also, try finding the one ballast in an office that is about to go bad & is giving off that distinctive aroma. With the thermometer, you can narrow it down quite quickly.
