Dryers are on 30-amp circuits, as are water heaters. Ranges are on 40-amp circuits.

The National Electrical Code calls for 10/3 wire for a dryer. The version now in use calls for "10/3 WG" wire - WG means "with ground" meaning there are four wires in the jacket - a bare one that's your ground, white which is the common wire, red and black which are your hot wires.

You don't NEED to use 8AWG on a 30-amp circuit that's less than 100 feet from the breaker to the outlet, but it's legal and some people do. If you needed 30 feet of wire to hook up the range, 12 feet for the dryer and 8 feet for the water heater, it's cheaper to buy one 50-foot roll of 8/3 than to buy the three wires you need by the foot.
