I’ve been running a 20hp Phase Craft converter set up for the last few years and it’s been flawless. I have a 60amp un-fused disconnect between the Phase Craft and the idler motor. I had the boys doing some cleaning/painting around the shop so I turned the power off to everything.
I turned the single phase converter power power back on but forgot to flip the idler disconnect switch. The 20hp idler made the awful noise it was supposed to for 1.5 seconds until the power was turned off.
I usually turn the disconnect off on my little Blanchard grinder but I must’ve forgot. I looked over and seen the white magic smoke rolling out the top of the magnet controller. It still works the way it’s supposed to....for now
I won’t repeat the idler disconnect mistake but I don't want phase loss power going to my machines again. The idler motor FLA is 48 at 240V.
1) Would a solid state overload relay placed before the 3 phase load center protect the idler motor and phase loss?
2) Is the relay install just hooking up the power in/out and the ground?
3) Does it matter which way the idler motor spins? I’ve read some conflicting opinions on that.
Thanks in advance.
