Question for the experts: Does that method really work?  I do get a buzz sometimes when i touch the back-plate of my computer, maybe a screw in a wall can fix that, but would it be enough if there is a real electrical fault?

I am pretty sure that a screw in the wall, will kill the IMI leakage current, put a wire from the metal part of your computer to the screw in the wall any thin wire will be ok

or to a metal stick rammed in the earth outside

will it be enough for a real electrical fault ?     NO WAY

Got it. Thanks Woolf.   I will try the screw in the wall for now.  I will need to research how to properly ground my appliances.

B.t.w. This IMI leakage current is it in any way bad for the computer?

Electricity is pure witchcraft to me

All computer power supplies have an IMI filter build in

If your electricity supply is 1 hot and 1 neutral the chassis will be at 60 volts for 120 volt supply and 120 volt for a 240 volt supply

that is if  the chassis is not grounded, the current will be a max of 0,15 mA for 240 volt  and half for 120 volt

it will NOT kill you

Americans have never noticed it, as the outlets there are grounded via the 3rd leg on the outlet

With the hot + hot supply  the center point at the IMI capacitors should be at  0 (zero)

but it the equipment has a single pole on/off switch well  you will have 120 volt at the chassis when switch is off, if not grounded

that is if the on/off switch is before the IMI filter

Well explained. Thanks again.

It is EMI not IMI

From Canada here with 110, can the electrician, hook up a 110 outlet in my shed so I can use my Canadian electric tools?

Probably better to get a transformer or Voltage Regulator large enough to run them. And don't let anyone near them or they'll plug them into 220.

Ask Smokey i believe he had his house wired for both 110 and 220.  I think you might have to have the power company install an additional transformer?

Thanks, any suggestions on what make/brand that could run a skil saw/ jigsaw, etc. ?

You probably want one rated at least twice the power of the device.  I would imagine the Skil Saw would require the most power.  Couldn't tell you a brand though.  Ace seems to have quite a few.

I use a Panther.   2000 Watt

Please post an update this thread every time you smoke a powertool by plugging it into the wrong outlet.

I wish you luck. It would be a miserable fail for me.

I fried a brad nailer (gun) by plugging it in the wrong outlet. Also a very good portable battery charger (jump box)/air compressor.

I do own a heavy 220 converter that weighs more than a USA car battery. It handles my saws and other tools with no problem. I can not remember the make of it.

If it's just the 2 tools, You might consider the cost of buying new 220 versions with the cost of an AVR.

I agree to a point. Each to his own.

I took some advice early on from a LinC thread and put red tape around the plug of any device I owned that was 110. Slowly but surely, (through complacency), I am burning up those devices.

If I had to do it again I would have taken what I could get at a garage sale in the US for my tools and purchased new here in the Philippines. Prices are good and you can use 220. In fact, I recently replaced a Dewalt hammer drill through Lazada and to my surprise...it uses 220!
