Weed Burden Protection (Power Drain Limiter)
If your fence's lowest run of wire or polyconductor is likely to contact weeds, brush, or other objects that will drain away the fence's charge, consider using this power drain limiter (product 06-14). It can keep power on the fence's other runs by limiting the amount of charge allowed to flow onto the lowest run. Install one power drain limiter at every point where power is fed into the lowest run.
