Have a 1 hp, 12 amp, 125V, single phase 6x48" belt sander with 12" disc sander. Thing must weigh 200 lbs! (same one Grizzly sells but with a different name as its older). Anyway, used it for years then moved and it started popping 20 amp circuit breakers. I replaced all the bearings about 5 years ago and it runs smooth as silk. Sometimes it pops breaker on startup and sometimes it doesn't. (I swapped breakers and same result.) As these caps are cheap, thought I would replace it to see if that is the problem. It only has one cap, the start cap and no run cap. The writing on the start cap says 400mf, 125V and Type 129. My Q is what does "Type 129" mean? And is it logical that a weak start cap could pop a 20 am circuit breaker? The existing one is certainly not burned, it looks new but know it isn't as I have had this sander since 2007. Thanks. Randy
