My table saw has the option for 220v. And I have 220v 50amp in my shop.

Problem is the plug I bought needs a large size gauge wire.
My table saw takes a small gauge size.

What options do I have?

 

[griz]

Change out the wire from the saw to what you need.

 

[Jim Port]

What size circuit does the saw call for? You may need to install a subpanel or a new circuit .

 

[jbfan]

Follow the instructions on the saw and install the correct receptacle.
No way that table saw needs a 50 amp circuit.

I know it does not need a 50amp circuit. But it is already wired for something else. The saw is not needing a heavy gauge wire. But the plug us not taking a smaller gauge.
I have a RV extension cord I can use and will fit the plug. But then I will need to drill out the box on the saw. I would need a new grommet?

remove the 50a receptacle and add a small panel. Then run a NEMA 6-20 receptacle off of a 20A DP breaker in the new sub-panel for the table saw. Put a NEMA 6-20 plug on your saw cord ensuring it is at least 12AWG cable. Now you don't have to run inside if the saw trips the breaker and you have the ability to add a few other circuits to the garage in the future.

Name/rating plate is the place to start.

That seems like a lot work to wire the saw?? I have 2 locations i will use the saw and they both have 50amp receptacles. Is there a rule of not provideding larger gauge extension cord then that is required.

I can see the point if I was adding a new plug, but I am not.

There are rules for plugging the equipment into the proper receptacles as specified by the manufacturer. I'm pretty the manufacturer of the saw or the motor does not specify a 50 amp receptacle or over current protection.

I don't think he understands that the rules you are talking about are for his and his equipment safety.

So lets try this. If you connect that saw to a 50 amp circuit, the first result of an electrical mishap will probably mean that your saw is smoked, you will never use it again. It could also result in a shock/electrocution hazard. Finally, it could result in burning down the structure where it is located.

You can leave your saw at 120V, or you need to replace the breaker and receptacle on that 50amp 240V circuit with the appropriate ones. Or, you can leave the 50amp as is, and run a new appropriate sized 240V circuit for the saw. It's your choice.

You cannot connect a 20A saw to a 50A circuit,
Without some form of protection such as a 20A breaker
Thats the code !

Huh? I have lots of circuits in my house , garage etc that have 15 amp and 20 amp breakers . I have lots of 2 amp table lamps , 8 amp tools etc plugged into them. The breaker protects the wiring not the device. Maybe the confusion comes from the fact you can't put a 20 amp outlet in a 50 amp circuit. That has nothing to do with saw. So you would need to wire a 50 amp receptacle and fit the saw with the an appropriate plug

saw male cord cap

look on the motor of the saw and find the FLA( full load running amps), size your wire,cord cap, receptacle and breaker to the FLA and your GTG

 

[theedudenator]

I was never under the impression the breaker protects the device. It protects the wiring in the wall?
So it seams I just need to find how to put a new gromment in the exit wire on my saw.

I am rather surprised by the various answers here. Some are obviously not correct. As my question was how to deal with an oversizes extension wire.

this is the best explanation!also very good advice. but again it's your choice. this will also save you a lot of headaches!:vs_worry::vs_worry::vs_worry:

I believe you have been told several times what the proper thing to do is but you keep ignoring it.

Option 1: You could make a "portable" panel based using a 50A dryer cord routed into a small sub panel. Then install a 20A DP breaker in the sub-panel wired to a NEMA 6-20 receptacle and mount that receptacle on the same board as the panel.

Option 2: Change the feeder breaker to DP 20A and install NEMA 6-20 receptacle instead of existing. Wire gauge is overkill but not a code violation.


As many have stated you can't run a 50A circuit to a 15-20A motor load.

welllll! you could do the above, but you want like the results!guarnteed!:vs_no_no_no::vs_no_no_no::vs_no_no_no::vs_no_no_no:

i mean the 20 amp load on a 50 amp breaker, bad things will happen.

I know in both of my options a 20A breaker interrupts the circuit to the saw....
