We have a 4 pin wall socket
by Very Helpful
We just bought a dryer and realised for the first time that there were two standards for cable connections. We have a 4 pin wall socket and had bought a 3 pin dryer. Since it was second hand, we installed it ourselves and your webpage was very helpful in giving a quick guide on what goes where. We actually noticed that the in our older machine, the ground and neutral were both shorted to the body. I suppose that is ok based on what I've read so far.
