In new home in Georgia the requirement is 4 wire 220 plugs instead of the old 3 wire plugs. I want to use a 4 wire dryer cord & place a locking plug on it to plug into my Hummel cord. How would an electrician say to wire that adapter cord? Thanks

Just cut the white wire off your new 4 wire cord, you don't need a neutral, just black and red for power and a green to collect the smoke

On a 4 conductor set up, there are essentially 2 hot leads , one neutral lead and one ground lead.Your hummel cord has 2 hot wires and a neutral but most people consider the green conductor to be a ground.It's actually a neutral.

The above recommended wiring will work but I would recommend making the connection from your green conductor on the hummel cord to the white wire on the 4 way plug and ignore the green wire on the 4 way plug. The reason is that the white wires in many homes are thicker and can do a better job of handling the spent 220 power that your hummel sends along them

One other thing. Every modern electric panel has red and black wires to conduct hot voltage. The white wires inside the panel connect to the neutral bus of the panel which connects to the neutral power line outside your house/ utility poles. The neutral bus in the panel is then grounded to a copper pipe that is buried outside the home somewhere.The ground wire basically does nothing until there is some kind of massive over load in the electrical system.

I don't even know what a Hummel looks like.
the white wire is for 120v loads, when combined with the 240v loads
i wasn not aware a Hummel had clocks, timers or 120v controls
the ground and neutral are seperated after the main service disconnect
the neutral is a current carrying conductor, the ground is not.
but they end up at the same place at the main service disconnect
as a grouned neutral, so the neutral is often called the grounded conductor
not to be confused with the green grounding conductor

P.S. Hummell from Europe?? correct me if i am wrong but they don't have a neutral in Europe?
eveything is 220 volt
dose save them on copper as the wire can be smaller

Correction. The white wire should be capped and taped off. Don't cut a wire and leave any copper exposed unless it is ground. Ever. Cap and tape all loose connections. You could easily ruin a piece of equipment or kill yourself by leaving a bare cable anywhere near other wiring. The end of that uncapped white wire will eventually find a way to pierce another wire in your connections or find its way up into existing connections. You just don't want that to happen.
I am constantly checking and rechecking.

You know how two wires sitting side by side in a dark basement have a way of getting tangled. (we all do) Don't screw with wiring.

Good point. always cap unused wires.
the white wire is still a current path.

Hey yall. Sorry for not getting back quicker. We thought we wired the Hummel (German) the correct way but it acted like it was only running half speed. Like only getting 110/120. So we stopped. Thanks for the response. I appreciate it. Anybody know now where I can find that Stauf trowel w/ the holes at the top of the notches Not on their website. Thanks again. Gene

You can make sub panel that can plug into a stove or a dryer outlet. The panel that provide me 220 volts and 40 amps of service out of a stove and a 30 amp service out of a dryer. The panel is broken down into a 30 amp plug and 2 20 amp receptacles. I rarely have to use any plugs in a home. Thereby eliminating chase the breaker or worse find the burnt fuse in a dark basement. I honestly can't believe some of the stuff I see in a basement.

It is a pretty simple yet sweet little rig that saves a lot of time and hassle.

If you aren't sure of how to make one, hire an electrician to hook on up for you. Cost about 250 to do it yourself and about 350 for an electrician to make one.

You won't regret it.
