This is something all you in the US should have...... I'd say everyone but I don't know how it works in the rest of the world.

Now someone here must know what this is and why it is importain to us woodworkers. Be the first one to give me good correct answer and you get 100 points.

It's a circuit tester. Plug it into any standard 110 volt receptacle and it analyzes the electrical cicuit that it's wired to.

As to its importance.... I'd guess that if the receptacle is wired incorrectly it could be hazardous to certain tools. If the hot and ground wires are backwards, it seems possible that a router could spin backwards.... causing an unpredictable feed. It is also possible that a person could become a part of the circuit by creating a ground for the power.... Most everyone has heard of an electrician nic-named Sparky, neh?

Of course it also could prevent an electrical fire that might burn all of a woodworkers prized possesions.

It is a 110 volt circuit tester. It will also tell you if you have an incomplete ground .

If I combine the above answers and add a few comments I have what I'm looking for so I will award points to both.

OK let's start with AC power, it has the "hot" and "neutral", some older tools were not made to the standards we have today and the "neutral" and case of the tools were common. If you were to have a drop cord or outlet wired wrong or if the tool did not have a polarized plug you could end up with the case being the hot side. This is then a shock hazard..... The third wire or safety ground is there to protect you if the "hot"wire were to come in contact with the tool housing. (a lot of tools are what is called double insulated to keep all these things from happen). I can see this is getting to long so lets move on........

The router will not spin backwards if the wires are backwards....

The tester tells you if the "hot" and "neutral" wires are backwards and it tells you if the ground is missing. I had my saw running off a 12GA drop cord this summer and noticed a small "dent" in the cord...... maybe something fell on it or what ever. I got out my tester and guess what the ground was open... To be safe you need to check the outlets and drop cords.

BTW in case you need to know the black wire is "hot".... this is the wire that you put the switch in........ it may be other colors as well but not white which is the neutral wire and the one (white) that goes to the wider prong on the cord end or outlet.......

This is an "unlisted" message so unless you know about the wiring you might want to get a professional to do the repairs if this tools show something is wrong.
