A four pole (prong) receptacle is required in the building wiring, for any new wiring installed under the last few Code versions.
The appliances usually come set up for the older 3-pole receptacles 'coz there are more old houses than new ones. Although when I bought an electric clothes dryer recently, the saleswoman asked whether I wanted a three-wire or 4-wire cord.

Almost all the new ones have a clock or timer or somethin that runs on 110
so a neutral added to the 240 line is now a standard practice.
But almost all new appliances that use a 4 prong will tell you how to wire it to a 3 wire system.
A variation on this thread (if this constitutes a hijack, then feel free to slap me down):
If you are intending to use a gas dryer & oven/cooktop/range, is it still required to wire as if there would be electric?

NO
Gas dryer = gas line....and 120V outlet (for tumbler motor, timer etc)...you could use the outlet set up for the washer)
Gas stove = Gas line, and 120V outlet (for clock, timer, etc)
Thanks.
4 prong for everything but a welding machine.
A/C compressors are still wired with no neutral. Not sure why they haven't changed, but they are also one of the few things still hard wired. It seems just about everything is switching to plugs, which is probably a good thing.While we are on that subject, does a wall oven have to make the connection behind the oven, or is it ok to go down through the floor an make the connection underneath, as long as it is accessible and there is enough slack to pull the oven out? This is hard wired, not a plug.

That's because AC compressors are 240V-only equipment, so no "neutral" is needed. Same as a water heater, or a cabinet-type table saw. Unlike dryers, which are 120V/240V equipment.
The AC compressors use a 240V grounding connection. The old 3-wire dryer receptacles were 120V/240V non-grounding connections. However, the "neutral" was attached to the frame ground of the appliance.
NOW I get it. Thanks!
my new dryer only needs a 30 amp breaker
on 10/3 wire, 4 prongs...
