I certainly would never make such a recommendation. Does InterNACHI also provide supporting justification for the recommendation?
A very conservative estimate of the number of homes in the US with either an electric clothes dryer or an electrical range with a three-wire feed is 57,000,000, but could be as many as a little more than 96,000,000. That’s a lot of three-wire feeds, yet electrical fires or electrocutions attributable to the feeds, whether three-wire or four-wire, are rare.
Instead of recommending the receptacle outlet and its circuit being replaced, a more practical recommendation would be to verify the integrity of the connections. One of the main reasons for switching to a four-wire feed is that if the single grounded-grounding conductor were to become loose, the metal housing of the range or clothes dryer could rise to 120V with respect to ground. The four-wire feed almost completely eliminates that from happening, but so do good three-wire feed connections.
There is no readily available statistical evidence to tell us how many electrocutions were caused by three-wire feeds compared to four-wire feeds. There are approximately 200 fatal electrocutions in homes each year in the US. No major organizations that maintain databases distinguish between three-wire and four-wire feeds. They only get as specific as “Faulty appliances”, which is a very broad category.
The same is true with fires. the difference is that with fires, we know that only around 16%-20% of dryers fires are electrical. That includes gas dryers. It also includes things like motor failures. There are, at most, fewer than 4,000 electrically related clothes drier fires. The number of electrical fires with ranges is much lower, but as with clothes dryers, all ranges are grouped together. That’s fewer than 4,000 out of a minimum of 57,000,000; in other words .00007%. Or one out of every 14,250. That’s a very small number!
Appliances account for only 3% of all residential fires. The requirement for four-wire feeds was, like many other NEC requirements, a solution in search of a problem. In this case, they never found a problem. The development of the NEC is very heavily influenced by electrical equipment manufacturers, including wire and cable manufacturers. Requiring four-wire feeds was a boon to the wire and cable manufacturers industry. They get to sell a lot more wire and cable as a result of the four-wire requirement. As with so many things, follow the money to learn the real story.
