This was from papers that came with a Dryer I recently installed for someone. Part of this is also on the rear of the machine in the form of a label. Where does it say anything about removing the Neutral to Frame Bond ??

This was from inside the Installation Manual, which most people wouldn't even see after having gotten their instructions from the other sheet and Label on the dryer itself. (couldn't take a picture of that because I didn't have the Camera that day). It does mention removing the Bond, but it could be clearer I think.

Lighthouse, The 4-conductor cords are round not flat like the 3-conductor cords. All of the cord sets come with a strain relief (clamp) but I and many others have found them to be almost useless. Most of the 2-screw cable clamps that are used for NM cable are also approved for flexible cords so that is what I use instead of the clap provided.

I certainly think that those instructions could be made clearer, and that the first lot should mention the fact that when changing from 3-w to 4-w that the strap needs to be removed.

I think that terms such as "neutral grounding wire" will also be very confusing to the average person. [Linked Image]

This is from a Range that is mis-wired in the same fashion as we are discussing with Dryers. Both Dryers and Ranges come from the Factory setup for 3 wire hookup with the Neutral bonded to the Frame somehow. The Manufacturer's instructions (above) are somewhat lacking in detail or clarity. The 'Warning' Lists should mention removal of the bond somehow, but they don't.

This is the same Range (new wire for other reasons) with the bonding strap removed as it should be.

Why does the range or dryer use a neutral? I mean, if you can run 240V ranges and dryers without neutral in the rest of the world: Why not in North America? It would seem the simplest way of solving the problem. Is this perhaps one of those: "But, we've always done it this way?"

C-H,

On the Dryer 240v is used for the Heating Element, but the Motor, Light is 120v. the Ranges have Lights and Clocks that operate at 120v and Heating Elements at 240v.

The light on the dryer? That must be one of those fancy features only found in America [Linked Image] Why is the motor 120V?

Hmm,

Maybe there is no light in a Dryer. I get confused sometimes [Linked Image] Why is the Motor 120v? I don't know. We also have Dryers that operate on 120v and use Gas for Heat. So maybe the same motors are used just for ease of manufacturing.
