 Joules are a measure of power -- think horsepower

 

1.  Distance assumes multi-wire fence

       Multi-wire means at least one hot wire and one ground wire running entire distance of fence. If you
       are running a single hot wire, proper grounding is much more important, especially in dry conditions.
       It doesn't matter how big an energizer you pick, if the circuit cannot be completed because of lack of
       proper grounding or lack of a return ground wire. Single hot wire = choose a larger energizer.

 

2.  Ratings are for cattle and horses which are fairly sensitive to electric fence

       If you are using this on animals such as sheep or goats, choose at least one energizer larger than
       recommended on the chart.  Choose at least two energizers larger for predator animals such as
       deer, dogs, coyotes, bears, etc.  Call if in doubt - We're happy to help!   1-800-477-7135

 

3.  If you have voltage leaking insulators, choose a larger energizer.

     •Faded insulators generally leak voltage.

     •Insulators which place the hot wire close to a conductive post tend to leak voltage.

     •Aged porcelain insulators can develop hairline cracks and leak voltage.

 

4.  Peace of mind - If in doubt, call us to help you make a decision on the right
     energizer!  1-800-477-7135

     •Are you protecting high value crops?

     •Are you trying to keep predators out?

     •Are you putting up a perimeter fence?

     •Is this a feedlot?

        If you answered yes to any of these, choose a larger energizer!

 

While an M300 might look adequate on the chart with the appropriate vegetation load, if you are controlling sheep and have poor insulators you may really need an M600 or even a M1000.
