The Square D by Schneider Electric QO 20 Amp Single-Pole Tandem Circuit Breaker is intended for overload and short-circuit protection of your electrical system. This breaker offers 2 circuits in the space of just 1 and is compatible with QO load centers, CSED devices, and NQOD panel boards. The ANSI-certified and UL-listed unit is rated for 120/240 VAC and 10,000 AIR. All QO circuit breakers are equipped with the exclusive Visi-Trip indicator. When a QO Visi-Trip circuit breaker trips, the handle snaps to a midpoint position between "Off” and “on" and a highly visible, red indicator easily identifies the tripped breaker. This enables you to easily distinguish which breaker has tripped in a load center that may contain up to 42 different circuit breakers. QO circuit breakers have features no other manufacturer can offer. They come in many different sizes and can meet the needs of virtually every function in your home or business. These types of quality, industry exclusive products keep the Square D brand ahead of the competition and are builders' and electrical contractors' first choice in electrical protection.

Everything important about this breaker worked, but the metal hook at the back was an issue with my 8 year old Square D QO panel. I had to use a Dremel cutoff wheel to trim away a portion of the hook. Don't trim too much and it will pop into position correctly with no problem. I tried to fit it without the trim with no success. Good value otherwise.

So I am really just including this review to get a picture up for others. I read through a ton of reviews, and still messed up and got the wrong one. Ah well, in the end I will still be able to say I did it myself. :-) To get the tandem version I should have ordered QO1515, the model number without the T. Now that I know which one to get I have decided it is too expensive for my blood, so I just got the QO15, single. Of course, someday I will pay more, when I run out of spots and am forced to buy the tandem, but I have a couple spots left. :-)

This particular assembly features two (2) separate 20-Amp breakers in a single enclosure that is exactly the width of a standard Square D QO circuit breaker. Although the back of the assembly isn't shown, it has a pivoting metal "hook" at the bottom that you engage before plugging the top of the breaker (which has a metal yoke type, plug-in connector) into the panel before it snaps firmly in place. This breaker will not fit the older Square D QO panels that us bolt-in breakers. I installed two of these tandem breakers in a compact Square D subpanel in my garage that had two breaker spaces and was rated at 60-Amps. The subpanel is a Square D QO2LL60NBNM QO "60-Amp, 2-Space 4-Circuit Outdoor Main Lugs Load Center w/ Non-Metallic Enclosure and Neutral ($27.27 current price on Amazon). So, now I have an outdoor subpanel with (4) 20-Amp 120v circuits at a material cost of a little over $65.00. VERY good value! This set-up would also work great in a detached shed, guest apartment, studio, shop, etc. Remember to bond the subpanel to the main breaker panel.

Great product but you have to plan your circuit assignments and breaker requirements carefully because SquareD only makes 15-15, 15-20 and 20-20 tandem breakers. They don't make a 20-15.

Difficult to find tandem breakers in 15/20 configuration. Perfect for my application. Fits QO style panel only.
