LIGHTNING PROTECTION
LIGHTNING PROTECTION KIT
A lightning strike at any point on your 'live' fence wire causes an instantaneous major voltage rise and a flow of current back to the energiser rather than away from it.
This power surge can damage your energiser.

FOR MAXIMUM PROTECTION
Disconnect energiser at power source and switch cut-out switch to OFF position prior to major electrical storms.
Use of a voltage spike protector will minimise risk of damage from a power surge from the mains power supply to the energiser.
Use of a spark gap between the fence and the energiser earth pegs, in a crows foot configuration near the energiser, will protect the energiser from lightning strikes.

LIGHTNING PROTECTION WITH CROWS FOOT EARTHING
Choose a location in either the lead out wire or first section of live fence wire that is as close to the energiser a practicable.
Install a spark gap (lightning diverter) into this location.
Connect the energiser fence supply to one terminal of the lightning diverter.
Connect the fence to the same lightning diverter terminal.
Connect the second terminal of the lightning diverter to the central earth peg of the crows foot earth configuration.
Connect the energiser earth lead to any one of the outer earth pegs of the crows foot earth configuration.

HOW THE PROTECTION KIT WORKS
The choke causes the power surge generated by the lightning strike to literally bounce back.
The surge then takes the shortest path to ground via the Lightning Arrestor.

INSTALLATION
Choose a position in either the lead out wire or first section of live fence wire that is as close to your energiser as practical.
Cut the wire and rejoin with strain insulator inserted.
Attach the choke to the wire using two joint clamps as shown below.
The spacing between the two clamps should be 600mm [2 ft] with the insulator midway between the two.
The lightning arrestor is installed [usually on a fence post] on the fence size of the choke.
NOTE : If fitted on energiser side, energiser is not protected.
Clamp one arrestor lead to the live fence using a joint clamp.
The other lead is wired to a series of interconnected earth stakes.
The number of earth stakes in the lightning protection earth should at least equal the number of stakes in the main energiser earth.
Use 2.5mm [12½g] insulated cable for lightning arrestor leads.
