So I am moving into the new house this weekend from circa 1992 trailer, which has 3 wire main while new place is 4 wire,( counting ground), so I have been assuming I would need to change the cords on the stove and dryer but I did not look at them beforehand, so I bought new ones at Home Depot yesterday and just now went to move the dryer and was surprised to see it has the same 4 prong cord and outlet as the new one I bought , the dryer and stove are both at least a few years old, both bought used. The stove plug also has 4 prongs, so I don't understand why the old wiring is this way, the dryer outlet has a separate ground wire as well as the two hots and a white. I seem to remember having to change the cord on the dryer when I got it , I knew nothing about the 3 vs 4 wire, but I do not understand why the old trailer would have 4 prong outlets, not that I mind, will make things easier but i don't get it, is it just a matter of the breaker rather than the main service wire?
