NEMA 14-30, 240V 30A, 4-wire, clothes dryers
NEMA 14-50, 240V 50A, 4-wire, electric ranges
NEMA 10-30, 240V 30A, 3-wire, clothes dryers
NEMA 10-50, 240V 50A, 3-wire, electric ranges

In the US, with systems installed before 1996, it is common to find NEMA 
10 3-wire devices which lack a ground (earth) pin. As of the 1996 NEC, new 
installations should be using NEMA 14 4-wire devices. With NEMA 10 
devices, the practice was to bond the metal frame of the appliance to the 
neutral wire. These older installations are still allowed for existing 
circuits only (with some very specific restrictions) per 250.60 "Frames of 
Ranges and Clothes Dryers" (1996 NEC), later renumbered to 250.140 in the 
1999 NEC.
