Wiring for 220V tools.

[jafenske]

I'm am going to buy a Oneida dust collector and a sawstop this weekend. Both are going to be 220V(I'm in the US). I need to do some electrical work this weekend to get power to the right places. I don't have any other 220V tools. Do these tools wire directly to the breakers or will I need outlets. Thanks for the help.

You will need outlets I suspect.  You should contact a local electrician.

You can probably wire the two either way depending on amperage draw, but it would be more convenient to have some electrical sockets installed in the various areas you might want to set the tools up in. Multiple electrical sockets eould allow you to move things around in future if you find the layout you chise doesn't work as well as you hoped. You might want to have each socket wired to an individual circuit as well.

It could be a plug, but better as a hard wired connection into a switch.

If you have 220v then you also have the electrician (sparkie) put in a couple of euro 230v outlets if you fancied some NAINA tools. A couple of US220 outlets also make sense.

It is possible you could install the outlet boxes and pull the wire and then have the sparkie do the rest. It depends on the electrician. If you use the wrong sized wire it results in no savings if it is a do-over.

I have my table saw hard wired to a breaker.  The rest of my 220 tools are plugged into outlets on the wall. This gives me flexibility moving equipment around if needed.

The fact you are asking the question implies you do not know enough to do the job yourself.  I prefer outlets, not wired directly to the breaker.  Just unplug the tool to disconnect the power.  I'm not sure circuit breakers in a panel are meant for switching on and off frequently.  I suspect in the 30-40-50 year life of a circuit panel that most of the breakers are only turned on and off three or four times total in all those decades.  Outlets are designed to have the plug pulled in and out all the time.  Never wear out.  And when I change blades on my table saw, I always unplug it so it has no power.  The breaker person would have to switch the breaker on and off a couple times a day for changing table saw blades.  Can circuit breakers handle this much switching?  Also by putting in a 220 outlet, I could always turn off the breaker if I wanted if I did not want to pull the plug.  And of course switch off the breaker if working on the outlet itself.  220 30 amp breaker you need 8 or 10 gauge wire for medium length runs.  I use 12 gauge wire on all 110 volt runs in the house.  I don't believe in using the minimum size wire required.  Bigger wire is better.

And the big wall switches are for tools that are wired, but one want to turn them on/off.
