[QUOTE="RossKean, post: 1347735, member: 19880"] Ken I understand that an electrically conductive grease is MANY times more conductive than a silicone-based dielectric grease. I would, however, argue that the PRIMARY mode of electrical transmission is by direct metal-to-metal contact and that there is little added value in conductive vs dielectric grease if the physical connection is robust between clean conductor surfaces. The value of conductive grease enters when you have inadequate clamping force to punch through oxide/dirt/grease layers on the connectors (loose connectors, oxidation, insufficient surface area contact for current load). I was just posting a couple of relevant items I saw on-line; not trying to bust your chops with respect to an area where you clearly have first-hand expert knowledge. (You obviously took my comments in a way I did not intend!) In my opinion, the primary value of either grease is to inhibit ingress of water/air which will promote oxidation/corrosion. Conductive may give you an edge if the connection is imperfect for one reason or another. By the way, I have tried to get carbon electrically conductive grease around here and it is simply not available in this (small) city. I would have to order the stuff. [/QUOTE]
