Mini Split Wiring: A Detailed Guide to Connecting Your Mini Split to Your Home
Mini split air conditioning systems offer a convenient and energy-efficient way to stay cool during the hot summer months. At the same time, they are extremely versatile and reliable, allowing homeowners to install them anywhere they’re needed. However, mini splits require some specific wiring connections in order to operate. Knowing how to do this can save money by avoiding costly mistakes. In this article, we’ll explain the basics of Mini Split Wiring and provide some important tips for getting it right.
Step One: Gather the Materials and Tools You’ll Need to Wire Your Mini Split
The first step to mini split wiring is gathering the necessary materials and tools. You’ll need a few items, depending on the type of installation you’re doing:
- PVC conduit
- THHN/THWN wire, either twisted pair or stranded
- Emt, liquidtight, or other suitable conduit
- An appropriate sized circuit breaker
- A voltage tester
- Wire cutters
- Wire strippers
- Electrical tape
- Screwdrivers
Step Two: Turn off the Voltage at the Breaker
Before you start wiring your mini split, the power must be turned off at the breaker. This can be done by switching off the breaker, or simply by turning the voltage tester to the “off” position. If you’re installing an outdoor unit, you’ll also need to disconnect any nearby metal poles or fences that might act as an antenna for incoming electricity.
Step Three: Run the Wire and Secure It in Place
Once the power is turned off, you can begin wiring your mini split. Careful consideration should be taken into account when running the wires. It’s important to choose the path of least resistance, meaning the wire will run along surfaces that are easy to access, are dry, and are not subject to any corrosive elements such as water, sunlight, humidity, etc. Secure the wire with straps, zip ties, or other supports as required.
Step Four: Connect the Wire to the Mini Split
Once the wire has been run and secured, it’s time to connect it to the mini split. If applicable, remove the factory-supplied cord from the indoor unit to make room for the new wire. Separately feed the wire from the circuit breaker through the PVC conduit or other approved wiring specified in step one. Next, connect the wire to the terminals in the indoor unit and seal the connection with electrical tape. Then, connect the wires to the terminals in the outdoor unit and secure with a strap. Finally, connect the negative and positive wires together with the circuit breaker at the breaker box.
Step Five: Test the Connection
Once the wiring is completed, it’s important to test the connection to make sure it’s working properly. Do this by turning the breaker switch back on, then using the voltage tester to test the line voltage entering the unit. If the reading is within acceptable limits, you’re all set. However, if it is outside of the recommended range, you need to inspect the wiring to make sure it’s not damaged and that all connections are secure.
Conclusion
Mini split wiring can be a complex process, but if done correctly, it’s well worth your time and money. If you’re not confident in your abilities, consider hiring a professional to help you with the installation. At the same time, be sure to turn off the voltage at the main breaker, run the proper type of wire and conduit, and secure it firmly in place. Once the wiring is complete, test the connection to make sure it’s working properly before powering up your mini-split.

They can provide expert advice on how to properly wire your mini split and make sure the job is done right.
Mini Split Wiring: Best Practices for Installation
Mini Split Wiring is a critical component when it comes to installing an air conditioner. As an integral part of the system, proper wiring is paramount as it helps ensure reliable performance and energy efficiency. To avoid wiring issues, manufacturers and qualified HVAC technicians recommend the following preventive action.
Consult With a Qualified Technician
Prior to the installation of a mini split, it is important to consult with a qualified technician. The technician should be familiar with air conditioning systems, as well as local wiring and building codes. This will help ensure that the wiring is done correctly and meets all safety standards.
Understand the Manufacturer’s Requirements
Prior to starting the wiring process, it is important to understand the manufacturer’s requirements and recommendations for installation. This includes the necessary connectors, wires, and other components that are needed for installation. If these components are not installed correctly, it may lead to wiring issues down the road.
Choose the Right Wiring
When wiring a mini split, it is important to choose the right wiring. This includes looking at the type of metal and insulation used in the wiring. The right metal and insulation are important as they help ensure that the wiring is durable and safe.
Get Professional Help

Ensure Proper Connections
It is also important to make sure that the connections are made properly. Connections should be tight and secure, as loose connections can lead to shorts and other issues. Additionally, all connections should be clearly labeled for easy identification in the future.
Check for Continuity
Once the wiring is installed, it is important to check for continuity. This is done with a continuity tester and helps to ensure that there are no loose connections, shorts, or other types of wiring issues.
Inspect the Wiring
After the wiring is done and the connections are secure, it is important to inspect the wiring. This can be done visually or with a multimeter. This helps ensure that all connections have been made correctly and that the wiring meets all safety requirements and standards.
By following these manufacturer recommendations and taking proper preventive action, mini split wiring issues can be avoided. Consulting with a qualified technician, understanding the manufacturer’s requirements, choosing the right wiring, getting professional help when needed, ensuring proper connections and checking for continuity, as well as inspecting the wiring can all ensure that the wiring is done properly and without any problems.
