[ICOM] PW-1 220 VAC US wiring?

[Kent Hufford]

Thanks.

Tho, my old dryer(one year old upright) had a 3-wire plug and my NEW house
has a 4-wire socket.

So, I followed the instructions in my old dryer's owners manual and changed
the plug on the dryer to 4-wire<g>

My Dryer is FINE.... I fixed that.  

It's the PW-1 I'm trying to hook up.

Thanks,
Kent

Googling "4-wire 240 vac" produced many answers and one of the better from:

http://www.nojolt.com/Understanding_240_volt_circuits.shtml

which says, in part:

"I previously mentioned "straight" 240 volt appliances, but there is another

class of 240 volt equipment; some appliances (such as clothes dryers and
ranges) 
use 240 volt current to power their main function (drying clothes or cooking

food) but use 120 volt current to power accessories such as the clock on
your 
stove or the light inside the oven, or the digital readout on your dryer 
controls. That is why some 240 volt circuits have four wires:

1) A black wire which is often known as the "hot" wire, which carries the 
current in to the fixture.
2) Another "hot" wire which is red, which also carries current in to the 
fixture.
3) A white wire called the neutral which completes the electrical circuit
for 
the 120 volt accessories only.
4) A bare copper wire called the ground, the sole function of which is to 
enhance user safety.

At one time, the code allowed for one insulated wire to function as both
ground 
and neutral in 120 / 240 volt combo circuits, but now all such circuits must
use 
the 4 wire scheme. This is why your new dryer (or electric range) might have
4 
prongs on its plug and your old dryer receptacle only has 3 holes. In which
case 
article 250.140 of the 2005 N.E.C. (National Electric Code) allows for the 
"pigtail" (the cord and plug assembly) to be changed to match the old 3 wire

receptacle as long as certain conditions are met. The National Electric Code

allows that, but your local code might not, so check first, or even better
yet 
make a deal with the appliance dealer to do it for you. "
