Rated 5 out of 5 by from Suitable for expanding existing and new panels Sparky1983 fromSeminole, FL, USA suggests these are only for panels before 1965. So why do new Square D panels allow you to expand number of circuits using tandem breakers. Sparky 1983 is incorrect. All you need is look at description for new Square D panels.

Rated 4 out of 5 by from Panel Upgrade Breakers Works well. I bought these for a fuse panel upgrade. Just watch out that per code you don't need an arc fault or ground fault interrupt breaker instead. These are very much more expensive.

Is located by the cash , un convince because if you have any questions you have to drag the electrical knowledge employee from back of the store to the front. The staff in every department knows a lot about each trade.

Can bridged single pole (QO2020CP) replace double pole (QO220CP)

Can a bridged (I see the holes in the handle) Square D Single Pole 20 Amp QO® Tandem Circuit Breaker Model: QO2020CP replace a Square D Double Pole 20 Amp QO Plug-On Circuit Breaker Model: QO220CP for a 3000 W electric wall heater?
Asked by: Anonymous
Sorry no. If you connect the two handles together, you are still connected to only 120V, not 240V that define double pole breakers. If you put two of these breakers side by side, then if can use the below accessory (QOTHT) to tie the two middle handles to create a double pole breaker inbetween two single pole breakers.

Can I use the Square D QO tandem circuit breaker to wire a 240 volt circuit?

Asked by: Anonymous
You cannot use this Square D QO tandem circuit breaker for a 240V circuit. But, if you use manufacturer part number QOTHT, It will "convert any two adjacent 120/240Vac single pole side-by-side tandem breakers to independent trip two pole."

My square D panel is full and I want to add a 2 pole breaker for my hot tub. All existing 120 circuits are being protected by 15 amp tandem breakers.

My ? is......Can I use the tandem breakers andtie the two center poles together to make a 240v circuit which would free me up some more room on my panel. I did install them and metered them and it is giving me a 240 v circuit. I am however concerned about safety. Thanks in advance.

If you notice the photo above, there is a hole in the middle of the two handles. Square D offers a part number to "convert any two adjacent single pole side-by-side Tandem (also called space savers) breakers to independent trip two pole." This part number is QOTHT. See photo below. Bill J
