Does electric fence put out AC or DC?
A term used to describe electric fence controllers that pulse electricity at regular intervals through a fence, typically at one-second internals. An output capacitor is used to store direct current (DC) electricity between pulses through a fence. Alternating current (AC) can’t be stored using a capacitor.

How long does battery last on electric fence?
We always recommend the use of leisure and deep cycle batteries with electric fencing as, unlike car batteries, they are designed to be repeatedly discharged and then re-charged. This battery should have a life of 200 cycles and can last up to 2-7 years if treated correctly.
Why does my electric fence click?
Clicking is part of normal fence operation when a charger releases energy that travels along the fence. … Almost all radio noise generated by electric fences is caused by a spark or arcing of the electrical current across fence hardware.

If the fence extends over 500m away from the main earth it will be necessary to add an additional earth line to the bottom of the fence and bury a stake at those intervals. Wire is a better conductor than ground so a ground rod every +/- 500meters will greatly increase the effectiveness of the fence.
Do electric fences start fires?
The only conceivable, but still unlikely, scenario where an electric fence could start a fire is when a wire shorts to a grounded metal object, such as a steel post or wire where insulators have broken, in the presence of abundant dry vegetation.

These rods should be about 10 feet apart and should be placed at the start of the fence. Grounding rods can actually interfere with phone service as well as electrical lines that may be located on the property. For this reason, it’s important to place grounding rods as far away as possible from utilities.
What are joules Watts?
Watts are defined as 1 Watt = 1 Joule per second (1W = 1 J/s) which means that 1 kW = 1000 J/s. A Watt is the amount of energy (in Joules) that an electrical device (such as a light) is burning per second that it’s running. So a 60W bulb is burning 60 Joules of energy every second you have it turned on.
