I was just out in the shop…turned on my 3hp Griz dust collection system and I heard a pop, turned around and saw some sparks and smoke coming out of the on/off control panel. Bummer!!

Make sure it’s all clean, and there’s no dust in the switchgear there.I suggest you take it apart and make sure a build up of swarf-wood-dust might have shorted it it has been known. Alistair

look for fricasseed critters! lol.

We have a 3 HP/3Ph exhaust fan in the boss’s big shop up in the rafters.

The switch gear and power box are down below on a big panel.

One day I went in and flipped the power switch and a great cloud of BBQ smelling smoke emerged along with mounds of exciting sparks and strange thumping noises.

It turns out a big chameleon had crawled up in the switch box and a bird flew in to get it. As I flipped the power the bird, chameleon and at least 2 of the contacts made Rond- aye – Vous.

Well, I opened up the switch box…no critters or bugs, nor anything else in there that I could see. It appeared to be pretty well insulated from outside dust, etc. At any rate, the large white wire from the power source (wall outlet) was burned in two where it was connected to the thingy-majig. As is obvious, I’m not mechanically inclined. The impeller was spinning after all power was off, so hopefully there is no issue with a frozen shank or something like that. I’m assuming it would not be a wise idea to simply replace the switch box without having someone check out the motor and other aspects of the unit? I would hate to replace it and it do the same thing again. Any other thoughts? Thanks for the interest.

Hope it’s an easy fix!

Just curious what is the load limit on that circuit ? And current draw of the DC ? Good idea to have it checked out.

Since the white wire is burned and it’s supposed to be neutral, my guess is that is came in contact with one of the hot wires or contacts.

If the white wire is burned off check to see if it was grounded out . A 3hp motor should be on 220 volts so that makes the white wire one leg of the 220 volt system.

The white wire, Hot in this case, might have been trapped between the cover and the box. After a while the insulation gave way and it shorted to ground burning the wire off.
This is a common fault. To fix use a wire nut to join the white ends together.
