Multiple (maximum of 2) low voltage 30 ft (9 m) extension cords can be used to achieve a total lead length of 60 ft.
Any more than this could result in a voltage drop off affecting trap performance.
To protect the cord from lawn mowers etc, we recommend placing it underground (2-3 inches) in a slit trench. Do this by inserting a spade into the ground and moving it backwards and forwards to create a shallow slit that the cord can be pushed into. Replace the dirt and stand on to compact.
