Clean Storm Reverse6-15R Power Joiner – Convert Dual 120V to 240V (3 Wire)

Part Number: Reverse6-15R

This Clean Storm Reverse6-15R power joiner allows you to operate 230–240V equipment using two standard 120V outlets. This is a temporary power solution commonly used in garages, workshops, and job sites where 240V power is not available.

How This Power Joiner Works

This unit combines two separate 120V circuits from opposite electrical phases to produce 240V power—similar to how a 2-pole breaker works inside your electrical panel.

• Plug both cords into separate outlets
• Press the test button
• Green light ON = correct phase / ready for use
• No light = move one plug to a different outlet

⚠️ Required Phase Warning

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

• Same phase = unit will NOT work
• Different phase = 240V output

If the unit does not work, it is almost always because both outlets are on the same phase—not because the unit is defective.

⚠️ GFCI Outlet Warning (Very Important)

Most garage and outdoor outlets are GFCI protected.

This product will NOT operate correctly on GFCI outlets.

GFCI outlets monitor current balance. Because this unit combines two circuits, it can cause the GFCI to trip even when working properly.

Options:

• Use non-GFCI outlets (where permitted)
• Use outlets in different rooms
• Consult a licensed electrician for a proper 240V circuit

Split style and wall AC units often use the 6-20R AND 6-15R.

Used by Sawstop Safe Saw and air conditioning wall units.
We now use the combo receptacle NEMA 5-15 / 6-20 so it can be used with either type of plug.  The difference is the dash 15 can have 15 amp breakers and the dash 20 will have 20 amp breakers but the the 6-20 can be used with all 6-15 equipment.

May not work with GFCI or LDCI 115 volt Outlets.

   The above photo shows special order 15 amp breakers installed.  The default breakers are 20 amp breakers. 

Plastic Box is 6" X 6" X 4"
We no longer make this unit with the voltmeter installed, rather replaced the meter with a smaller green light.  This allowed the box to be reduced in size from an eight inch box to this six inch box.

Note: User assumes all responsibility on use.  It is the users responsibility to check the inbound voltage, outbound voltage, and total amp draw to verify these are not going to be overloaded.  The user agrees to test the amp draw of any appliance or machine that they plug into these converters to ensure they are not being overloaded. Meters are cheap and mistakes are expensive.  You can purchase a meter at https://www.steam-brite.com/voltage-meter-mulitester-p-6259.html 
User agrees to hold Steam Brite, its employees, and agents harmless in the event of any use of said use of converter.  The user agrees to not hold SteamBrite and all employee against any problems that arise out of the use of said converters/ inverters.  Remember, just because it plugs in does not mean it is OK to use!

Please remember the 80/20 electrical rule.  If you are going to plug into a 15 amp 120 volt outlet and draw long term the device needs to be under 80% of 15 amps = 12 amps max.
If I plug into dual 120v 20 amp breakers long term then the 80/20 rules math is 20 amps X 80% = 16 amps max draw.

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.

Electrical Requirements Checklist

• Two separate 120V outlets required
• Outlets must be on opposite electrical phases
• Outlets must NOT be GFCI protected
• Circuits should be 15 amp minimum
• Verify wiring with a polarity tester
• Confirm voltage output before connecting equipment

Why This Product Exists

Many homes, garages, and job sites do not have dedicated 240V outlets available. Installing a permanent 240V circuit may require permits, electrical work, and added cost.

This power joiner provides a temporary solution for running 240V equipment using existing 120V circuits when used correctly.

Real-World Customer Use Cases

• Garage wood shop setup (table saws, dust collection)
• Testing equipment before installing permanent 240V power
• Temporary job site setups
• Running equipment in rental or shared spaces
• Backup power option when 240V circuits are unavailable

Troubleshooting Guide

• Depress phase location button / No green light: outlets are on same phase — move one plug
• Breaker trips: equipment exceeds amp capacity
• GFCI trips immediately: unit is not compatible with GFCI outlets
• Machine runs weak: voltage drop or overloaded circuit

Important Power Limitation Reminder

This unit does NOT increase available electrical power.

• Two 15 amp circuits = maximum 15 amps at 240V
• Continuous loads should be reduced further for safety
• Always verify actual amp draw under load
