The Pulsara connectors ensure a good join between the rope, wire or tape. If conductors are poorly connected, the shock behind the connector can be too small or may have disappeared. This will make the electric fencing much less eff ective. It is important to use a rope joiner, tape connector or wire clamp for every connection to ensure the current continues to pass through. NB: Rust has an insulating eff ect, which will reduce the voltage on the fence. The metal connectors of Pulsara are treated to prevent rusting.
