Product Overview

Siemens offers a wide array of thermal-magnetic circuit breakers that are the key element for overload and short-circuit protection of your homes electrical system. To provide additional protection Siemens offers circuit breakers to protect against severe electrical shock or electrocution, mitigate the risk of electrical fires and protect against damaging surges and Voltage spikes. Circuit breakers are intended for switching and protection of your home's wiring from high temperatures caused by excess current higher than the rating of the wire. While thermal-magnetic circuit breakers are the key element for overload and short-circuit protection of your electrical system, there are potentially dangerous conditions that do not involve over current.
  • Twin single pole, 20 Amp, 120-Volt type QT interchangeable circuit breaker
  • 10,000 AIC interrupting rating
  • Siemens type QP circuit breakers provide easy plug-in connections in Siemens enclosures and the time saving insta-wire feature
  • Compatible with Siemens PL and ES series load centers
  • Use for overload and short-circuit protection of your electrical system
  • Thermal-magnetic

This did replace one single pole (full size) breaker in my box; which is mfg'd by Siemens. the model is W0816MB1200ct. I am not an electrician, however so I'm not familiar with other brands.

will this fit my g4242mb1225 ITE panel?

Answer

No. The G4242MB1225 load center would be a full circuit load center and will not accept the type QT tandem style breakers. You can only use the standard full size QP style breakers.

I have a 4040L1200c and a 3030B1100C and they will not work in theses breaker boxes. I had purchase a couple of tandem breakers and they will not fit in properly. I talked with Siemens and was told that my boxes were not rated for them. The only thing you can due is call them and ask or purchase on and see if it fits properly.

Will this work on LC3040-1200 MUYRRAY

Answers

LC3040-1200 is not a valid catalog number. Please check your label. Whether you have LC3040B1200 or a LC3040L1200 you should see the Type QT breaker listed under the branch breaker column on the label showing it as UL approved. Please see link for reference. No modification is needed to allow installation. https://s3.amazonaws.com/dcc-data-extract/new-delta/asset/Compas/daily/Compas/2019-08-21/Wiring%20Diagram/MUY_WD_LC3040B1200.pdf

Answer

EQ24-416 was an 8 space 16 circuit load center which means, yes, tandem breakers are approved. Your model predates the circuit total limitation features which was introduced circa 1968. For load centers like yours the non-CTL versions of the QT breaker were made available. Q2020NC will not have the rejection feature and will fit and be approved for use in your load center.

Yes, that is the same panel that I have and I just installed 8 of these tandem breakers to add more circuits. If you look at the diagram on the inside cover they can only be installed on the bottom 5 positions on each side. When I researched what the QT indicated the Siemens website said it was the tandem version of the QP breaker.

Can I switch a 15 amp tandem single pole to a 20 amp tandem single pole breaker

Asked by Bubbles1 June 18, 2019

Answers

ONLY if the wire for the circuit you are asking about IS wired with #12 AWG wire. The number of receptacles on the circuit is irrelevant. The overall number of receptacles only offers a greater ability to overload the circuit because of the available opportunities to plug in more devices. Every device that you plug into a circuit adds to the overall electrical load on that circuit, so you can overload a circuit with 1 device that has a rated electrical draw (load) that is greater than the overcurrent protection (Breaker) of that circuit. Likewise, you can plug in many devices that have a low rated electrical draw (load) ie. led lights before the total sum of their (load) exceeds the rating of the circuits overcurrent protection (breaker). The overall capacity of an electrical circuit is that of the lowest-rated component of the circuit, and you don't want that to be the wire. 15 amp circuit =#14 AWG wire 20 amp circuit=#12 AWG wire. 20 amp breaker and wire rated for 15 amps #14 AWG and the wire fails before the breaker trips.

I had a breaker that kept tripping. Swapped out everything inside, and it would still trip. Even with nothing plugged in. I went with Siemens for their long history of quality products. So far, after a week and half, no trips.
