The new rec's wired with 10/3wg have 4 contacts and use a "4wire" pigtail to the units. Most dryers and ranges come with a bonding strap from the chasis to the nuetral, you remove the strap on a "4wire" install and connect the equip. ground to the chasis and the nuetral to the normal nuetral lug. You should be able to do the same with older models. Hope this helps.
