Electrical Question from Josh about Buffers That Trip Circuit Breakers

Received from Josh in LA

[ad#block]Question: I have a 120 volt buffer that draws 12 amps and is rated at 1500 rpm and is dc rectified.The brand of it is a Mercury Floor machine burnisher. All of my service receptacles are 20 amp single receptacles (not a duplex) and are on their own 20 amp breaker. My workers still trip the breaker every now and then. Is there any device I could install on the buffers to regulate the amperage that is drawn.

Dave’s Reply:
Thanks for your electrical question.
Hey Josh – I am totally familiar with this scenario. The first thing that comes to mind is installing a speed control switch on the buffers that is rated over the 12 amps that the motors draw. The problem is the initial starting amperage surge. Another possibility would be a Soft-Start device. This is such a common problem with buffers used that I am surprised that the manufacturers do not build in a soft start circuit.
