Installing Your Smart Splitter

Before You Begin:

Please read and fully understand all directions and safety information before you begin installing your Smart Splitter.

Locate your electric panel and ensure that the circuit breaker for this 220v outlet is turned OFF. This breaker is usually 50 Amps and proceeding without switching it off can be VERY dangerous.


Required Tools:

One (1) Phillips Screwdriver


Step 1

Turn off the breaker to your 220v outlet and unplug the device that is currently occupying it (i.e. EVSE, electric appliance, etc.)

Step 2

Verify that the back of your Smart Splitter and your 220v outlet match.

Step 3

Use a screwdriver to remove the screws on the face plate of your outlet.

If your outlet orientation is right-side-up, remove the screws on the top of the outlet's face plate. If your orientation is upside-down, remove the screws at the bottom of the face plate.

Step 4

Use a screwdriver to screw in the bracket screws (x2) in order to secure the mounting bracket to the faceplate.

Step 5

Plug in your Smart Splitter (it feels good, we know).

Ensure that the breaker for your outlet is OFF before you plug in your device.

Step 6

Use the provided thumb screws (x2) to secure your Smart Splitter to the mounting bracket.

Step 7

Plug your original device into the Primary Output (left side) of your Smart Splitter.

The device plugged in to the Primary Output will always take priority over the device plugged into the Secondary Output. Normally this would be your dryer, water heater, or other electric appliance.

Step 8

Plug your EVSE cord into the Secondary Output (right side) of your Smart Splitter.

We do not recommend using an extension cord with your Smart Splitter. Many extension cords do not meet the same safety certifications as your Smart Splitter.

Step 9

Turn on the circuit breaker to your outlet and verify that your Smart Splitter is receiving power by ensuring that the indicator lights are on.

Here's Where it Gets Tricky...

(Just kidding, it's actually pretty simple, but our different models require different setup instructions from this point.) Select your model!


Appliance version


Dual-Car version

Set the current limit for your EV to 24A either in your car or on your EVSE. This helps to prevent too much electricity being pulled from your outlet.

In order to charge two cars simultaneously, set the current limit on both of your EVSEs to 20 Amps or below. In some cases you may need to manually adjust the charge speed or current limit in your EV itself.

To charge one car at a time, set the current limit to the maximum rate allowed by your car or EVSE. Keep in mind that the maximum current allowed on a NEMA 14-50 outlet is 40 Amps.
