So I have a friend with a cabinet shop who was having problems with one of their old dust collectors tripping breakers, so I ended up with it. Its an older (1999) Grizzly with a 5hp motor. It probably weighs 200 lbs...
I figure its just a start or run cap going bad so not too bad so far, however I cant find any info on the motor, except the nameplate which worries me a little.
So its 5hp, 220V, 60 hz 3450 RPM but nameplate states 34 amps which seems quite high. I figured that a 5hp should run somewhere around 25 amps, which would be nice, but doesnt seems to be the case.
Trying to figure out circuit sizing and it's a bit disappointing. I guess I'll have to go with 8 awg to cover the 34 amp*1.4 per 430.32. I was hoping that I could use a regular 30 amp twist lock... Oh well, hard wired it will be.
Anyway, that's all fine and dandy, but I have no solid info on replacement start/run capacitors. It looks to have come with a 600MFD (µF, I really dislike the M), and at some point it looks that someone paired up a couple 50 MFD caps in place of the old run cap. So if I get new ones, does it look unreasonable to get a 600 for start and a 100 for run? how big of a difference does it make.
A lot of me just wants to find a similar sized 3hp 3 phase motor and toss a VFD on it, but then I need a frame size and shaft adapter. There is no winning.
I'll probably end up trying to shoehorn a cyclone into my basement with an ~8' ceiling...
