What would be the conditions that would occur if this were the case?
How would you define low voltage?What would be the conditions that would occur if this were the case?
All the smoke will leave the motor and it will need to be replaced.
If the insulation on the motor windings could take the higher voltage, is there at least a chance that the motor's overload protection would shut it down before thermal damage occurred?
If you want to get technical, 480V IS considered "low voltage".What would be the conditions that would occur if this were the case?
That's usually what precedes questions like this in my experience.I know that at least one 230 volt motor connected to 480 that caught fire.
I didn't do it. I just had to repair the wiring going to it. That also caught fire.
That's usually what precedes questions like this in my experience.
I see it the other way more often actually, where they have a 230V supply but they connect the motor for 460V, then can't figure out why it stalls all the time.
- Fire happens,
- Investigation takes place,
- Determination that the wrong voltage was applied (or more often that the wrong connections were used),
- Someone sees the nameplate and says "But it says it is 230 OR 460V, which means it can handle either one. So why did it catch on fire just because we hooked it up wrong?"
