Electric Gate Wiring: The Importance of Proper Installation


Electric Gate Wiring

Electric gates are popular for homeowners and businesses wanting to increase their security and convenience. These gates are effective in keeping unwanted visitors out and provide a sophisticated touch to the overall look of the property. 

However, it is essential to understand that electric gates are complex machines that need proper installation, maintenance, and wiring to function correctly. Therefore, this article will cover some of the basics of electric gate wiring and why it is crucial to ensure proper installation. 

The Definition of Electric Gates

Electric gates are mechanical systems that operate with electricity instead of manual power. They can be divided into two main types: swing gates and sliding gates. 

Swing gates operate by swinging open on hinges like traditional doors. In contrast, sliding gates move along a track installed on the ground or suspended above it. They are operated using various methods, including remote control devices or keypad entry. 

The Importance of Proper Wiring for Electric Gates

Proper wiring is essential to ensure electric gates function smoothly without hitches. Faulty wiring can cause numerous issues, such as power surges, short circuits or even complete malfunctions, which may cause damage to your gate operator system or risk endangering anyone using the gate itself. If left unaddressed, electrical problems with automated gating systems may also lead to safety hazards, including fires or electrocution. 

Furthermore, another reason why proper electrical setup is vital for electric gate systems is that they require specialized parts that demand particular voltage requirements and wire gauge sizes, as well as specific grounding techniques for them to operate at peak efficiency levels while being safe enough for regular use by people entering or leaving your property through them. Overall, electrical problems with automated gating systems could lead to significant downtime if not caught early during routine maintenance practices – which means lost time, revenue, and customer satisfaction for businesses. 

Types of Electric Gates

Electric gates come in different types, catering to various needs and styles. Two of the most common electric gate types are swing and sliding gates. Each has advantages and disadvantages, depending on space availability, security requirements, and aesthetic preferences. 

Swing Gates

Swing gates are the traditional type of gate that swings open and close along a hinge on one side. They come in single-leaf or double-leaf configurations, depending on the opening width they must cover. 

Swing gates can be made of aluminium, iron, wood, or vinyl. They can be customized in different styles for improved curb appeal. Swing gates require ample movement space since they need sufficient clearance to swing open fully without hitting obstacles. 

They are ideal for residential properties with wide driveways or commercial sites where a grand entrance is necessary. However, swinging outwards may cause safety issues if vehicles pass by too close or people stand nearby when opening/closing. 

Sliding Gates

Sliding gates operate by sliding back and forth along a track instead of swinging open like their counterpart. They may consist of one panel or several panels that slide parallel to each other for wider openings. 

Sliding gates are commonly made from aluminium because it is lightweight yet durable enough to withstand harsh environmental conditions. The primary advantage of sliding gates over swing gates is that they require less space since clearance is unnecessary as they slide along the fence line instead of swinging outwards. 

This makes them ideal for residential areas with limited clearance rooms or commercial sites where saving space is necessary while providing maximum security. However, sliding gate systems are more complex than swing gate systems due to their additional mechanical parts, like tracks and rollers, which may require more maintenance. 

Electrical Components of Electric Gates

Motors and Actuators

One of an electric gate’s most essential components is it’s motor or actuator. The motor is responsible for moving the gate, and the actuator is the mechanism that converts the energy from the engine into motion. 

These components come in different sizes and strengths depending on the size and weight of the gate they are powering. Motors can be AC or DC-powered, and actuators can be hydraulic or electromechanical. 

When selecting a motor or actuator for your electric gate, it is essential to consider factors such as speed, torque, power supply requirements, and compatibility with other electrical components such as control boards. Proper maintenance of these components is also crucial to ensure their longevity and optimal performance. 

Control Boards and Circuitry

Control boards are another essential electrical component of electric gates. These boards manage the operation of various elements such as motors, actuators, sensors, safety devices, keypads, intercoms and other accessories that may be connected to them. 

They regulate all electrical functions within an automated system, including timing sequences for open/close cycles. The circuitry involved in these systems varies depending on whether your gate operates as a swing or slide operation with single/dual motors & actuators using them. 

It’sChoosing a control board that accommodates your specific configuration needs is essential. Ensure this component has all required features necessary for proper functioning, including surge protection (for protection against electrical spikes), error codes (for easy troubleshooting) & programmable options (for customizing settings). 

Safety Devices (Photo Eyes/Safety Edges)

Safety devices such as photo eyes and safety edges play a crucial role in ensuring the safe operation of automated electric gate systems. They optimize security parameters at access points surrounding perimeter fencing, whether at residential or commercial sites.

Photo eyes serve as sensors specifically engineered to detect any obstacles in the gate’s path. Upon detecting an obstacle, photo eyes transmit signals to the control board, thereby initiating the gate to either reverse its direction or cease its movement.

Safety edges, on the other hand, incorporate pressure-sensitive switches. These switches trigger the gate to reverse its direction whenever they come into contact with an object.

In the case of a sliding gate, it is customary to install safety edges on both sides.

However, in the case of swing gates, they are generally positioned in close proximity to areas where potential hazards may arise.

These safety devices provide an additional layer of protection, ensuring the safe functioning of automated electric gate systems by actively preventing accidents and potential harm to people or objects in the gate’s vicinity.

When choosing safety devices for your electric gate, it is essential to consider factors such as compatibility with your control board, wiring requirements, and their positioning for optimal protection. Regular maintenance is also crucial to ensure they work correctly when needed most. 

Wiring Basics for Electric Gates

Electric gates require proper wiring to function reliably and safely. The wiring for electric gates connects the power supply, control board, motors, and sensors. 

Before starting any wiring project, it is essential to understand the basics of wiring requirements. This section will cover voltage requirements, wire gauge and type, and grounding considerations. 

Voltage Requirements

Electric gates typically require a 120VAC or 240VAC power supply, depending on the motor’s size and voltage rating. Most residential electric gates use a standard 120VAC power supply. However, the gate requires more power than what is available from your home’s electrical service panel. In that case, it may need a dedicated circuit or subpanel installed. 

Choosing the correct voltage when installing an electric gate is essential to avoid damage to the motor or other components. Exceeding the rated voltage can cause overheating and damage to parts and decrease their expected lifespan. 

Wire Gauge and Type

Selecting the proper wire gauge for your electric gate depends on several factors, such as distance between components, amperage draw of each element, and environmental factors like temperature changes or corrosive conditions. The most common wire gauges used in electric gate installations are 18 AWG up to 12 AWG copper wires, depending on application needs. 

For longer distances between components like motors and control boards, thicker wires like 10 AWG-12 AWG will provide less electricity flow resistance, reducing wires’ potential overheating. Thicker Wires are also helpful in harsh weather conditions as they have improved insulation properties preventing water penetration into wires, possibly leading to corrosion. 


Grounding provides a path of least resistance for electrical energy in case of short circuits in faulty electrical devices such as motors or control boards. To ensure the appropriate grounding of an electric gate installation, it is essential to include a dedicated grounding wire in the wiring.

The regulations outlined in the National Electric Code mandate the use of appropriately sized “equipment grounding conductors” in accordance with the electrical load and specific application requirements.

Grounding is essential because it helps protect people and animals from electric shock by providing a path of least resistance for stray electrical currents. In addition, a properly grounded electric gate system can prevent electrical surge damage to its components and help ensure safe operation for years. 

Wiring Diagrams for Common Electric Gate Setups

Swing Gate with Single Actuator

A swing gate with a single actuator is a simple yet effective electric gate setup. The actuator is responsible for controlling the opening and closing of the gate. In contrast, the control board manages the power supply and direction of the motor. 

The power supply for the electric gate setup is sourced from a dedicated circuit breaker or fuse box, ensuring it is appropriately rated to meet the voltage specifications.

Wires are then installed to connect the power source to both the control board and the actuator motor.

In the case of incorporating external access controls like keypads into this setup, it may be necessary to run additional wiring from those controls to the control board.

Swing Gate with Dual Actuators

To accommodate larger swing gates or those requiring a higher weight capacity than what a single actuator can provide, it is common practice to utilise dual actuators. This setup allows for more evenly distributed weight distribution across two motors rather than one. Wiring for this type of electric gate follows similar principles as a single actuator setup but with twice as many components. 

Apart from connecting both actuators to the control board in parallel, it may also be necessary to run wires between the actuators to enable communication during operation. Furthermore, since dual actuators consume more power compared to single actuators, it is crucial to use an appropriate wire gauge when running power lines.

Sliding Gate with Single Motor

Sliding gates are another popular electric gate setup that utilizes just one motor (instead of two like in dual-actuator swing gates). Wiring for a sliding gate setup is similar to a swing gate with a single actuator. Still, instead of controlling the motor to move the gate in an arc, the control board manages the direction and speed of the engine to slide the gate along a track.

This setup commonly utilizes power and ground wires, as well as two control wires (one for each direction).

Furthermore, if access controls such as remotes or keypads are utilized, you will need to wire them into the control board.

 Sliding gates also require additional wiring for their safety devices (such as photo eyes or safety edges). 

Troubleshooting Common Wiring Issues

Power Supply Issues

One of the most common issues with electric gate wiring is related to the power supply. A proper power supply is essential for any electrical device’s functioning. 

If your gate is not receiving adequate power, it may fail to operate or may move slowly or jerkily. A few things to check when troubleshooting power supply issues include: 

  • Verify that the voltage required by the gate aligns with the voltage output of your power source.
  • Inspect all fuses or circuit breakers to ascertain that none of them are blown or tripped.
  •  Testing electrical outlets with a voltage meter to ensure sufficient voltage. Suppose you cannot identify any issues with these items. In that case, it may be time to call a professional electrician who can use specialized equipment to diagnose problems.

Control Board Malfunctions

Another issue that may arise with electric gates is control board malfunctions. The control board is responsible for processing signals from various sensors and devices and translating them into movements for the gate. 

If the control board fails, there can be no communication between these sensors, which causes malfunctions in the movement of the gate. To troubleshoot a potential control board issue: 

– Check all cable connections from sensors and other input devices leading into the control board – Inspect circuitry on the control board for damage or defects 

– Ensure that there are no loose wires anywhere in your system. In certain situations, it may be necessary to obtain replacement components or even a complete new unit if your control board has sustained irreparable damage. 

Sensor or Safety Device Failures

Electric gates rely on several safety devices like photo eyes and safety edges, preventing accidents while operating.Despite the intended purpose of safeguarding individuals and objects from harm when using an electric gate, it is important to acknowledge that these safety devices can encounter occasional malfunctions. To troubleshoot sensor or safety device failures: 

  • Verify that all sensors, safety edges, and photo eyes are free from any obstructions or blockages.
  • Ensure secure and undamaged wiring connections for these devices.
  • Check that the power supply to these devices is operating correctly. If you cannot identify an issue, it’s best to contact a professional technician who can help isolate the problem and provide the appropriate solution.
