Materials
The first step in building an electrified gate is to select material that conducts electricity well. The exact design of the gate depends upon what type of animal will be confined in the pen. Metal tubing or angle iron works well either as a frame or as the whole thing. If needed, you can also add some sort of wire mesh stretched over the frame to keep the animal occupants from exploring between the metal frame pieces. Don't forget to include an area on the gate that is insulated so you can easily open and close it without getting shocked.
Electronics
Three types of charging systems provide the electrical current from which the fence and gate system gets it's name. The first and most powerful is a 110 volt system you plug in. This is your most reliable choice, according to the website DareProducts. Another option is a 12-volt battery system, though you should keep in mind the battery needs to be checked periodically. A final alternative is a solar-powered system which, though energy efficient, might not always provide enough of a jolt to get an animal's attention.
Grounding
It's the nature of electricity that a grounding system must be installed for the electric fence to work. Without proper grounding -- three 6-feet long ground rods spaced ten feet apart -- animals could touch the fence all they want and never feel even the slightest shock. The big idea here is to make the gate an extension of the entire system, with the primary goal being to provide easy entrance and access for you while carrying the electrified current from one side of the gate to the other.
Considerations
There are various types of electric fence gate design. In addition to the standard one we mentioned, there are also steel tube, bungee, and singe-wire gates, any of which might suit your purposes and craftsmanship skills. Keep in mind that, no matter how many hot wires you decide to run on the gate, you still need a grounding wire to make the system work correctly. As long as the electrical current stays consistent and your building materials are conducive, feel free to experiment with different designs.
