How to Install Soft Start on RV AC

RVs are a great way to enjoy the freedom of the open road while still having all the comforts of home. However, one common issue that RV owners often face is the power demands of their air conditioning units. RV AC units tend to draw a lot of power when they start up, causing voltage drops and even tripping circuit breakers. This problem can be eliminated by installing a soft start device on your RV AC unit. In this article, we will guide you through the process of installing a soft start on your RV AC.

What is a Soft Start?

A soft start is a device that helps reduce the initial power draw of an electrical appliance when it is turned on. It gradually ramps up the voltage and current, allowing the appliance to start up smoothly and without causing any issues with the power supply.

Benefits of Installing a Soft Start on RV AC

There are several benefits to installing a soft start device on your RV AC unit:

  • Reduced Power Demand: The soft start device reduces the initial power demand of the RV AC unit, preventing voltage drops and circuit breaker trips.
  • Improved Energy Efficiency: By reducing the power demand during startup, the soft start device helps improve the overall energy efficiency of your RV AC unit.
  • Extended Lifespan: The soft start device helps reduce the wear and tear on the compressor and other components of your RV AC unit, potentially extending their lifespan.
  • Compatibility with Generators: Soft start devices are compatible with most generators, allowing you to use your RV AC even when you are off-grid.

Step-by-Step Guide to Installing a Soft Start on RV AC

Before starting the installation, make sure you have the following tools and materials:

  • Soft start kit (make sure it is compatible with your RV AC unit)
  • Wire cutters
  • Wire strippers
  • Electrical tape
  • Screwdriver set
Step Description
1 Turn off the power supply to your RV AC unit. This is important for your safety.
2 Locate the electrical panel of your RV. Remove the screws or cover to access the wiring.
3 Identify the wire connecting your RV AC unit to the electrical panel. This wire is usually thicker than the other wires and may be labeled as ‘AC’ or ‘Air Conditioner’.
4 Cut the wire connecting the RV AC unit to the electrical panel, leaving enough length to work with.
5 Strip the insulation off the ends of the cut wire using wire strippers.
6 Connect the wires from the soft start device to the cut wire. Make sure to connect the right wires according to the manufacturer’s instructions.
7 Use electrical tape to secure the connections and prevent any exposed wires.
8 Reassemble the electrical panel and tighten any screws or covers.
9 Turn on the power supply and test the RV AC unit with the soft start installed.

It is always recommended to consult the manufacturer’s instructions for your specific soft start device and RV AC unit to ensure a proper installation. If you are not comfortable with electrical work, it is best to hire a professional to install the soft start for you.
