Clean Storm Reverse10-30R 80kA Surge Protected 240V Power Joiner

Part Number: 20240538

This unit converts two separate 120 volt outlets into 230/240 volt single phase power using a NEMA 10-30R receptacle. This version includes Square D HEPD80 80kA surge protection to help protect connected equipment.

⚠️ REQUIRED: Understanding Electrical Phases (READ BEFORE USE)

This product ONLY works when plugged into two different electrical phases.

• Every breaker panel has TWO phases (left side and right side)
• Half your outlets are on one phase, half are on the other
• You MUST plug into one outlet from EACH phase

If both cords are plugged into the same phase, the unit will NOT produce 240 volts.

How to test:

• Press the test button
• Green light ON = correct (240V ready)
• No light = move one plug to another outlet and try again

📺 Watch: How to Find Opposite Phases

How It Works (Simple Explanation)

This unit combines two 120V lines from opposite phases to create 240V. This is the same concept used inside your breaker panel when a 2-pole breaker is installed.

You are essentially creating a temporary 240V circuit using two separate outlets.

Deeper Explanation (Why It Sometimes “Does Not Work”)

Inside your breaker panel, circuits alternate between phases as you go down the panel.

• Left side breakers = alternating Phase A / Phase B
• Right side breakers = alternating Phase B / Phase A

If you randomly plug into two outlets, there is a 50% chance they are on the same phase.

When both outlets are on the same phase:

• You will measure ~0 volts between them
• The green light will NOT turn on
• The unit will not function

This is NOT a defect — it simply means you need to move one plug to a different outlet on the opposite phase.

Tip: Outlets in different rooms or on opposite sides of the building are more likely to be on different phases.

Top 5 Mistakes (Avoid These)

• Mistake #1: Plugging into two outlets on the same phase → unit will not work
• Mistake #2: Assuming any two outlets will create 240V → only opposite phases work
• Mistake #3: Not checking amp draw → can trip breakers or overload circuits
• Mistake #4: Using GFCI outlets → unit may not function properly
• Mistake #5: Thinking this increases power → it is limited by the wall circuits

Will This Work With My Machine?

If any of the above are not met, this unit may not work correctly.

Tips:  One customer wrote, "I plugged into different walls, not the same outlet, and it did not work."

Answer:  This is incorrect step / understanding.

In order to have the power supply box work, it must be plugged into different phases.

There are two phases of power in every home.

Half of all the outlets are on left phase, and the other half is on right phase.

You must land on one of each phase in order for the power supply to work.

This means if I just randomly select two outlets in a home, I could be plugged into:  two left side phases, 2 right side phases, or 1 of left + 1 right (correct use of power supply, depress phase locator button on the power supply box and will illuminate bright green on the phase locator light if you plugged in correctly.)

If you look at the breaker panel (photo to the right) and notice the column of breakers on the left side and then a column on the ride side.

The way a breaker box is wired is the top left breaker is left phase, the 2^nd from the top left strait down the left column is right phase, 3^rd down is left column is left phase, 4^th down is right phase.  These breakers alternate phase location all the way down each column.

The top right column of breakers works exactly the same way.  You have to land on one left phase and and one right phase to make this item work.  It is OK to have landed on a pair of outlets that is left and right side and each is positioned anywhere in the breaker panel.

Since this power supply box will not work with GFCI or LCI outlets you can also replace a GFCI outlet with a standard wall receptacle.  

Optionally, if the two breakers you want to use are on the same phase, simply change the location of one of the two breakers to be in a different position in the column.   This is very easy to do and only takes a screw driver (see video link below.)  Go outside and turn off the breaker and turn off the breaker that is labeled as ‘main.’  Go back to the garage and take off the garage panel cover.  Grab the breaker you want to relocate and simply switch positions with another breaker either one up or one down in the column.   You can change the location of the breaker or change the location of the wire in the breaker (your choice.)  This will put the breaker on a different phase.  Again, see video below on how to do this.

Once you are on different phases, and press the momentary phase location button on your power supply box, the green light will be bright green telling you, you selected one left and one right phase and you are good to use this power supply box below the required amp draw of the wall outlets you plugged into.
