The best way is doing a continuity test with a multi-meter. On most meters the sign

is the Greek letter omega,,, set meter to continuity and touch both probes together,

set meter so you get a sound when they are touched together. Now place one probe

on the plug end and one on the service end, this will tell you which hole,, or inner or

outer sleeve is neg. On the outlet plug end 120v the larger of the two is neg.

How do you properly ground an electric fence?

You need to have a grounding rod made of galvanized steel that is driven straight into the ground until only half an inch of bar is remaining above ground. The ground rod should be at least 6 feet in length. Drier land areas normally require a longer grounding rod, or more of them, spaced 10 feet apart. The ground rods themselves should be placed in [an] area[s] that are naturally permanently moist to have any effect. Then you have to run a grounding cable that is attached to the ground rod along the bottom or top of the fence (can be the top wire or bottom wire) all the way to the fence charger. This cable needs to be attached to the ground rod by ground rod clamps That grounding cable should be attached to that fence charger in order for the fence to be properly grounded. Check out the following links on tips and instructions on how to properly ground an electric fence.
