Well, my BII showed up this week and it looks great, but I can't use it until I install a 220V receptacle. The plug on the grinder looks like a standard 3 prong, with one of the blades turned sideways, it is a 250V/20A plug. This is similar to a table saw I also have. Looked at the wiring the electrician did when the outlet for the table saw was installed, and it looks like he used standard 3 wire Romex (12/2 guage) with both the white and black wires being hot to get the 220V from a double pull breaker. Does this sound correct? Where is the neutral wire for the neutral bus in the breaker box if both the white and black wires are hot? Any wiring gurus out there with any advice? Ken
 
The machine is wired to run on 220 single phase.
When you go to your breaker panel you will find that it is fed by two black wires and one white or in some areas one red one black and one white. A voltmeter will show that from the black to black or from the red to the black there will be 220V and from either of the blacks to the white there is 110V.

An electricial will check the leads on the male plug from the machine and wire the wall plug accordingly to match the colour coding. ie red will plug into red, black to black etc.

This is a job for a qualified person.

Whoa! Wait a minute! This sounds like a plug for 20 amp 120VAC service! Most plugs for home service are for 120VAC 15 amp service. Call Bader and make sure before you do anything. A 220V plug looks differently than what you have described.

I was trying to find a link for you to look at on the internet but relented and pulled down a Grainger's catalog for reference.

This is a picture of a 120VAC plug for 15/20A service.

I hope this works...

I checked both the plug on the grinder and the receptacle I bought for the grinder. These are both marked 250V/20 amp and are designed for the 220. I know most 220V circuits use 2 black wires or a black and red in addition to the white and ground wires, but that is not how the electrician wired the 220V outlet for the table saw. The outlet I got for the Bader also only has 2 screws for attaching wires along with the green screw for the ground. This is the same way the electrician wired the table saw, with the black and white wires attached to these 2 screws. I guess I'll have to check inside the breaker box and see how he wired the breaker on that end.
 
Wire normally comes with one black, one white and a ground. Proper proceedure when using this wire for 220 single phase is to connect both wires to the blacks in the box but you must use black tape to wrap around the white, once around, where it hooks up to the box and the wall plug. the uncoated ground is just that and connects to the green buss bar in the box and the green screw in the wall plug.

Occasionally you will get a plug in with three terminals and a ground, this is a special arrangement where there is a 120V control circuit switching the 220V on and off via a relay. It is not common and the plug prongs are usually arranged in a circular pattern.

I suggest you get an experienced person to check things out before going ahead, 220V packs and awful kick.

Where can I get some of that 220V? I've heard it's the best blade material for sabers. I believe Tom Mayo likes it, but not for heavy sabers--only light sabers.
 
Will,
You fit in with the rest of us smart-elics from Texas! Light saber......geesh!
ROFL!!!

George, expect more of the same when you come down to Austin in August!!! I don't understand it, not everyone appreciates our humor...imagine that!
