I am looking for a technical specification on the jacket thickness of CSA / ULc rated 12/2 landscape lighting cable. We have two types of 12/2 cable available here in Ontario. One is CSA rated and the jacket is much thicker then the cable that is not CSA rated. The copper inside is the same in both cables. If you have any information on this please help me out.... Also, if you know of a Manufacturer of the CSA rated 12/2 cable I would appreciate their contact information. Thanks and have a great day.
