I am not aware of any.
You can go to www.lonmark.org to see if they have any information.
The only cable information and/or cable sources that Echelon has are found in the 'Junction Box and Wiring Guidelines' engineering bulletin at
The bulletin also contains a list of cables (along with manufacturer/supplier information) that comply with Echelon wire guidelines.
Echelon does not validate whether a cable meets our wire specification. Cable manufacturers submit their cable to be included with the 'Junction Box and Wiring Guidelines' engineering bulletin.
