Electrical (woodworking related) question .... I have a Grizzly tablesaw wired at 220v. I moved into a rental that doesnt have any 220 outlets. Then one I think to myself ... "the dryer has a 220 plug". Here is my question...can I plug my tablesaw into the dryer plug using one of those 220v extension chords?

Sure, as long as the plug/sockets match. Keep the cord as short as possible to avoid a voltage drop.

I'll echo Lew with a resounding yes.

You may have to make a cord with the right plugs/receptacles to match the dryer outlet and table saw plug.

I would use a 10 gauge cord to minimize voltage drop.

 

its a Grizzly G0715P 2HP saw prewired at 220v with a 20A breaker. distance from plug to saw would be about 40 feet. I was thinking of making my own extension using 12 gauge wire but some are saying 10 gauge might be better to cut down on voltage drop. The option to just rewire the saw is an option, I just have to look at the owners manual and see whats involved.

With either 10 or 12 gauge, 40 feet is quite a distance for an extension cord.  I'll let Larry chime in here.  IMHO, I'd feel good with 20' but 40 may push it.

Definitely go with the 10 gauge.

I'm running 50' of 10 gauge (4 wire) cord supplying 220 Volts @ 30 Amps out to my converted 24' camping trailer shop.

It feeds a sub-panel where it is broken down into both 220, & 110 Volt outlets plus lighting.

I run a 110 Volt 15 Amp electric baseboard heater, and everything else off of this cord. I have yet to trip the 30 Amp breaker.

The cord I used was designed for RV use, and has extra heavy insulation.

The outdoor receptacle, & plug are rated for 50 Amp use.

I just checked the specifications for your Grizzly G0715P saw and it states that it requires 16 Amps @ 110 Volts, & 8 Amps @ 220 Volts.

According to your saws manual you could use a minimum 12 AWG gauge size extension cord for lengths up to 50'.

Below is what would be required for 110 Volt conversion.

 

 

Well, there ya go.

I solved the problem the easy way this afternoon  my local HD was having a tool sale so I picked up a cheap 110v table saw, spent half the afternoon putting it together and aligning it. Its junk compared to my Grizzly but it will do the job I need it to and I will not have to modify my pride and joy.

Thanks for the info guys (especially Larry and Rick). I just wasnt comfortable cutting the plug off my existing cord and rewiring it. sorry ...... 

Well, at least you know you can run the Grizzly on an extension cord if you run into something the new saw won't handle.

 

 

Glad to see you're back in business!

A dryer line - - yes.Yah  that's what it is, a 220 line  two hots that are put of phase with each other,  a neutral, and no ground.  The dryer probably has a 30 amp breaker.    Ground and neutral are bonded in the main breaker panel  in sub-panels the two are not bonded. 

 

Depending on the size of your motor (under 4 HP) You can also  just use  two out of phase  20 amp outlets and use two wiring the hots to  220, 30 amp twistlock

I ran a 1 HP Dayton motor for my Crapsman table saw like that for years and years.

 

About ruining your pride and joy:

You don't have to cut the plug to use the dryer.  Get some #10 ( or heavier)  three wire multistrand from the BORG a female inline plug for your saw and a make dryer inline plug and just make up an extension adapter to connect the Grizzly three prong to a dryer outlet.
