My house still does. We hang the sheets out during the warm weather months - gives them a fresh smell.

I've said it before on this Forum, and I'll say it many times again. The fact that something has not yet caused a disaster is not evidence that it is safe.

Soemthing that is inherently unsafe is different from something that has a long history of "safe" operation, but could be made "safer". It is hard to argue with tens or maybe hundreds of millions of installations that were done this way, consider the very low number of problems, and not come to the conclusion that it was a relatively "safe" practice.

A lot of these things are a matter of balancing the added costs of making something safer. One could argue that electricity is inherently dangerous. But the fact is, that it has made our lives much safer. Electric lights are far safer than gas lights, even if now and then someone does get electrocuted. I don't mean to be flip about it, but I suspect that gas or oil lantern lighting has probably killed far more people than electrical wiring in total.

If the added cost of the 4th wire caused some people to forego having an electric range and were to stick with a wood stove to cook on, it is almost certain that far more people would have died from the use of the wood stove than from the very slim additional risk of electrocution that not having the 4th wire poses.

I wonder if anyone even has any figures on whether anyone has ever been killed from this type of installation.

If it can happen it will. It takes just one stroke from a Sawzall or one turn from a spade bit to open a neutral amd create a hazard. By sharing the EGC and neutral, we have an exposed neutral which normally presents no hazard. So why not allow the neutral to be bare in all cases?

The cost of that 4th wire is not overwhelming. Just one life lost from this practice is not acceptable.

Lots of good info on the progress towards increased safety with household electricity. As an HI I feel I have more info to share with clients regarding these topics, thanks for all comments and discussion.

I don?t think that the cost of copper had much to do with it but the fact that we got slabs for free could have.
The first house that I lived in that didn?t have a wood cook stove in it was after I got married.
Hey I am still in school too.
