One of my most favorite power tools in my shop is my Performax (Jet) 16-32 drum sander. I use it on almost every project. However, for the last 15 years or so that I have owned it, this tool has frequently frustrated me because the motor circuit breaker frequently trips while sanding.
After investigating possible solutions to this problem, I decided to add an AC Ammeter to allow monitoring of the motor current while sanding. I was able to add this accessory without making any permanent modifications to the sander or motor circuit. In addition, the original 15 Ampere circuit breaker still provides circuit protection.
Addition of this meter allows me to monitor the motor current and adjust the conveyor speed control to keep the motor current under the 15 Ampere level, preventing the circuit breaker from tripping. I am amazed at how easy it has become to eliminate that vexing circuit breaker tripping problem! This change has greatly enhanced my enjoyment and appreciation of this wonderful tool.
