Sawstop, Grizzly, and Delta Unisaw Adaptor Power Cord Adapter Joiner (Reverse Converter)
Takes two 115 volt outlets and allows you to use 230-240 volt appliances that uses under 15 amp @ 230 volts (3450 watts) Single phase current to NEMA 6-15R receptacle.   Commonly used as an electric wall AC and split style air conditioners, SawStop table saws, Grizzly Shapers, Edge and Floor Sanders, Delta Unisaw, Gunsmith Lathes, 240v Drill Presses, Milling Machines, and Pressure washers.  Fast and Easy 240 Volts

Other 220 to 240 volt receptacles available including but not limited to: NEMA 6-30R, NEMA 6-50R, NEMA 10-30R, more




Perfect for electric cars (BEV), pressure washers, welders, plasma cutters, vapor steam cleaners, wall air conditioners and other high powered equipment when 230 volt plugs are just not available. 

Tesla (BEV) car owners historically have purchased the 14-30R or 14-50R model. 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.

To use simply plug into different outlets and push the momentary button to test voltage.  If the voltage read between 220 to 240 volts or you get the green light you are good to go.  Not all outlet combinations will produce the correct voltage so you have to test before each use.  If you push the voltage test button and it reads 120 volts, or does not display the green light simply re-located one of the power cords to a different location and retest.  Every job site location has the ability to provide plus or minus 230 volts.  If you use 15 amp 115 v to 120 volt circuits then you will only be able to operate up to 15 amp 230 volt equipment.  If your pressure washer needs 23 amps @ 230 volts and you are plugged into 20 amp 115 volt outlets, you will need to turn the pressure down to lower the amp draw.  Just turn the pressure regulator / unloader knob counter clockwise.  The less pressure, the less horse power is needed to turn the electric motor and this will lower the amp draw.   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.
