Scott is correct that the first number is the conductor to ground rating and the second is the conductor to conductor rating. Here is the information on the voltage rating from Lapp Group. http://content.lappgroup.com/fileadmin/DAM/Lapp_USA/Technical_Documentation/Cables/Cable_Voltage_Designations.pdf
There is some more information on Harmonized coding system at this link, but it doesn't cover the "G" insulation. http://content.lappgroup.com/fileadmin/DAM/Lapp_USA/Technical_Documentation/Cables/Cables_HAR_Conforms_CE.pdf Ted Eckert Compliance Engineer Microsoft Corporation [email protected] The opinions expressed are my own and do not necessarily reflect those of my employer. -----Original Message----- From: Aldous, Scott [mailto:[email protected]] Sent: Thursday, October 11, 2012 8:41 AM To: [email protected] Subject: Re: <HAR> cable designation question I did find a reference to this, though not from an "official" source: http://www.muellergroup.net/faq.html#10 Scott Aldous Compliance Engineer AE Solar Energy +1.970.492.2065 Direct +1.970.407.5872 Fax +1.541.312.3832 Main [email protected] 1625 Sharp Point Drive Fort Collins, CO 80525 www.advanced-energy.com/solarenergy -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Aldous, Scott Sent: Thursday, October 11, 2012 9:33 AM To: Peter Tarver; [email protected] Subject: RE: <HAR> cable designation question Hi Peter, Regarding the voltage ratings, according to a handwritten note I made on a printout from Oflex on my cube wall, the first number refers to the conductor to ground voltage rating and the second number refers to the conductor to conductor voltage rating for multiconductor cable. I don't remember where I got this from, but it seems to make sense since there are 2 layers of insulation between conductors.

I recently purchased a copy of HD 361 to decode <HAR> cable designations. An example is: H05GG-F H = harmonized cable 05 = 300/500 V G = ethylene vinyl acetate conductor insulation G = ethylene vinyl acetate jacket F = flexible conductors (Class 5) My interpretation of the two G characters is based on reading catalogs that indicate an inside to outside approach to designating the cable materials. Does the same inside to outside approach also apply to the voltage rating, as I expect that it does? 300 V insulation on the individual conductors and 500 V on the jacket? Regards, Peter L.
