I just bought a new washer and dryer from a big box store. I let them install it simply so I didn't need to be bothered. After they left I checked the back of the dryer and saw the conductors in the cord hanging out and exposed. I thought "typical" and decided to put a clamp in so the conductor didn't pull on the terminals. After I got the cover off, look what I saw. So no cable clamp and the obvious issue. Needless to say they have zero training but just 2 inches to the left of this is the diagram. I am only posting this because it seems everyday, in every area in society people are incompetent, or take shortcuts. I am not going to call the big box store because few will even understand. I just wonder how many dryers these guys wire in peoples home who don't know.
