Why is it labeled “12/3”?
The diagram could be more clear. The cable looks like it has 2 blacks in it.
It also shows the neutral somehow not being spliced at the middle switch.
The splices and slivers of yellow sheathing make the graphic more confusing than that circuit naturally is. I think it would be easier to see 12/2 or whatever starting at the right and left side with 12/3 only between the switches. Right now it looks like a single piece of 12/3 end to end (apparently not even cut through in the four way box), with the red conductor disappearing at the ends. The best illustrations of 3 switch circuits I’ve seen have always shown the electrical boxes to give better sense of what comes to a from each switch.
Understanding is good, but since the HI is only looking at function i am not really seeing the advantage to some of these recent posts. They are not going to be pulling switches out to check the wiring.
It would make more sense if the line leg was wired to the far right switch and the load leg was wired to the far left switch. Then it wouldn’t appear that the black conductors of the 12/2 cable assemblies were passing through the 12/3 cable assemblies.
The graphic implies that a 4-way switch can be used as a 3-way switch.
It also makes it look like there are two 12/3 cables between the middle and far right switch.
RB is correct. The same graphic of a switch is used for all three switches. All show 4 terminals.
This image has been updated at the link in the original post. Thanks, everyone.
I am still seeing the same 4 terminal switches.
To spell out exactly what Jim is saying, the three way switches should not show a fourth unconnected terminal. There should only be 3 terminals (and a ground).
Mirning, Jim.
Hope this post finds you well and in good spirits today.
I concur, doing more than SoP can place the inspector between a rock and a hard space, there are many times when a home inspector has the unique opportunity to observe how lighting switches are wired in a junction/gang box.
Just my 2 cents.
Morning, Maggie.
May I make a suggestion? Seeing that so many times new illusions for the association, and we are the largest, appear to have inconsistences’, wouldn’t it be logical to have certain members in on the project or at least proofing prior the illustration being released online?
IE: Robert Meier for electrical.
This does not bode well for the association. Remember, little pictures have big ears in this industry.
Yes, you are correct.
They have reached out to some of us. I have reviewed several graphics and articles however I did not review this one.
Thank you for that feedback. We will be removing those two terminals as soon as we can.
You did, here.
We do a cursory CME review but there are just way too many benefits to having them fully critiqued on this forum.
I don’t understand what that means. InterNACHI has the only ears left. Every other association went under.
I don’t understand what that means.
I was simply saying the HI is only going to report if they work correctly or not. They do not necessarily need to see how they are wired nor can they see much to ascertain any issues.
It’s my fault. Everyone tells me that I don’t understand what they are saying. I still don’t understand what you are saying. What change would you make to the graphic?
