There was a Dayton instruction booklet in the box with my new motor. It was pretty thick and I hoped it had all the wiring diagrams for Dayton motors or something else useful.
Nope, just the regular stuff in 3 languages but there was a chart labeled "minimum wire size".
It is designed to hold starting current (LRA?) under 5%. That is some scary stuff, like a 1/2 HP motor 50 feet from the panel requires #8.
I hope inspectors don't start calling this a 110.3(B) requirement.

Such a wire schedule must have been written by an attorney.
BTW, induction motors always pull the system voltage down more than 5% during start up -- though for a very brief moment of time.
After all, an induction motor -- upon connection -- is a bolted short.

Greg, you read the instruction manual? Must we take your "man" card away?...

In order for a 110.3(B) issue, the mentioned document must be made available to the inspector? Right?
Now, IF you wired it with #12 at 60', would you provide this document to the inspector?
On the other side of the fence, how many inspectors would ask for motor mfg docs, as opposed to looking at the nameplate data??

That's how instruction manuals are these days... nothing but a little bit of useless information repeated over and over in several different languages. I think the record number I've seen is nine (9!).  Of course... the English section is usually laughably flawed, in spite of it all.  Makes you wonder if they'll ever consider amending or dismissing 110.3(B)....  In order for a 110.3(B) issue, the mentioned document must be made available to the inspector? Right?

My last request for mfg info related to equipment being installed in a cabinet shop. Relocated from another town, and 95% is 'aged'. Lack of any readable nameplate data (in english), or sign of any NRTL labeling, I requested that some data is required.
Long story short, wow did they supply data; in english and korean! A manilla file folder for each piece of equipment at least 25+pages in each. Useful?? Time will tell.

Well Gents, it appears that as inspectors we are going to have to cave in a little bit when it comes to Signs in Article 600.33.
I can just see the expression on the installers face when I ask him for the instructions. Then when I tell him it is required he is going to Freak.

George As for coming up with the instructions, The technology has arrived. A young guy would Google it up and show it to you on the phone.
