Shock with sander Flipped breakers
« on: March 08, 2021, 03:40 PM »
I have a 150 sander. I was sanding today with a non-festool hose, and the dust deputy when I felt a shock. My breakers flipped and I flipped them back. However, now my sander isn't working on any outlet.  Is that it for my sander?  Is there a fuse somewhere in the sander Ian replace or something? I JUST received the dust deputy in the mail today and installed it.  I was sanding for about 45 seconds when is shocked.  Please tell me there's a fix.

Thanks in advance. [sad]

Do you have another Festool cord to try on the sander?

Did you buy an Ultimate Dust Deputy or one of their Static Dissipative units? If it is not one of their units designed to dissipate static and you you used with a non Festool hose (which I am going to assume is NOT anti-static) it is possible that you may have fried something. Are you in a cold dry climate? We’re you using it with a Festool vac and is it working? Is your sander under warranty?

So when you say "shocked", did you get an AC shock (from the mains), or did you get a static shock?

Yes.  It still did not work.

I've never had any issue with static effecting any tools that I've used this non-festool hose with.  I set up the small dust deputy and wanted to try it out. 45 seconds later, shock and done.  I'm in Iowa which is getting warmer, but still pretty dry.  Ridgid shop vac is still working.  I'll have to check about warranty.  It's less than 6 months old.

The Dust Deputy needs a ground itself. A piece of wire and a heavy washer or bolt that touches the ground works. They create a lot of static charge. No idea on your sander other than following the suggestion of trying a different cord. Could be completely unrelated, and the sander just may have shorted at that moment. The breaker blowing is a sign there was a direct short.

So your sander was plugged into a wall outlet, not an extractor then?

Out of curiosity, you might want to check your outlets with a simple plug tester, one that checks polarity, ground, GFCI (not required, but nice to have).   Check that they are wired correct and grounded.

The tool is double insulated, so the ground shouldn't matter, and polarity shouldn't matter 99.9% of the time. But I would be generally curious if either the tool or the vac had no place to dump the charge build up.

You can always look in the Festool EKAT to get a parts diagram for your sander in see if there is a fuse. I don't know what model you have of sander, so situations could vary. If it's brushed, maybe their is just a pile of carbon where a brush used to be, if it's electronic controlled, maybe the magic smoke is gone.  Does the tool smell?
