These “Qwik-Open” or QO breakers are the fastest opening breakers in use in the industry. They reportedly open after just one full power cycle of a 60 Hz AC line (about 1/60th of a second). These breakers feature a visual trip indicator and make it easy to quickly spot the tripped breaker in the panel.
What does QO mean on a circuit breaker?
QO® (plug-on) one-, two- and three-pole thermal-magnetic circuit breakers provide overcurrent protection and switching on ac and dc systems.
What is the difference between Homeline and QO breakers?
Both the series of panels use a different type of circuit breaker. Homeline is designed to meet all the necessities of the residential market, where qo is intended for the industrial lighting system. Homeline is a single-pole breaker, whereas qo is of two or three-pole breaker.
Are Homeline and QO breakers interchangeable?
These circuit breakers are used for overload and short-circuit protection of your electrical system. Square D Homeline breakers are compatible with Homeline breaker boxes and CSEDs. Square D QO breakers are compatible with QO breaker boxes and CSEDs. Each ANSI-certified and UL-listed.
Which is better Square D QO or Homeline?
Homeline is the “price competitive” model from SquareD, QO is the higher quality panel. The difference is probably mostly due to historical reasons given all the consolidations in the electrical manufacturing industry.
What is a QO Square D breaker?
The Square D by Schneider Electric QO 20 Amp One-Pole Circuit Breaker is intended for overload and short-circuit protection of your electrical system. The ANSI-certified and UL-listed unit is rated for 120/240 VAC and 10,000 AIR. and a highly visible, red indicator easily identifies the tripped breaker.
Are QO breakers rated for two wires?
He says QO and Homeline breakers are rated for only on wire period. Just because the wire can go on either side of the tab does NOT make it rated for two wires.
Are Schneider and Square D breakers the same?
Square D is an American manufacturer of electrical equipment headquartered in Andover, Massachusetts. Square D is a flagship brand of Schneider Electric, which acquired Square D in 1991.
Is Square D or Siemens better?
Square D electrical panels are also high quality. There are many electricians as well as homeowners who believe that the choice between a Square D electrical panel and a Siemens electrical panel really boils down to personal preference because they are both equally high quality.
Can Square D breakers be used in a Siemens panel?
No, the Square D breaker should not be installed in the Seimens panel and checking the label should show you that this is not recommended.
Why is there a shortage of Square D breakers?
Production activities of circuit breakers have been hindered due to nationwide lockdown imposed in many countries. Moreover, supply chain has been disrupted and shortage of raw materials occurred.
What is the difference between QO and QOB breakers?
A QO breaker is plug on mounting, and can be used in QO load centers, old NQO and NQOD panelboards, and current NQ panelboards. A QOB breaker uses a bolt-on connection to the bus, and can be used in old NQOB and NQOD panelboards, and current NQ panelboards. Otherwise the breakers are the same.
Is Square DA good panel?
The Square D by Schneider Electric QO612L100RBCP electrical panel for home applications is an excellent choice for those looking to place their breaker outdoors. It can also be used effectively as a subpanel if your main breaker board is already full.
Does Square D QO make quad breakers?

Are QO and QOT breakers interchangeable?
Class CTL & QO vs QOT In general, QOT (e.g., QOT2020) are the new version of tandem breakers designed to be used in present class CTL QO load centers. QO (e.g., QO2020) are circuit breakers are designed for use in the older “non-class CTL” QO load centers that were manufactured before the change in code.
How many receptacles can be on a 20 amp circuit?
The answer to the question how many outlets on a 20 amp circuit is ten outlets. Always comply with the 80% circuit and breaker load rule, allowing a maximum load of 1.5 amps per receptacle.

Are QO breakers switch rated?
Resolution: Per UL 489, the switch-duty rating label (SWD) may be applied to single pole 15 A and 20 A circuit breakers, 347 Vac or less that pass the special SWD test requirements. Tandem QOT and HOMT, and QB type breakers are NOT SWD rated.
Which circuit breakers are interchangeable?
Specified breakers are breakers that have been tested and listed for a panel by the manufacturer. Interchangeable breakers are breakers that have been tested in the panels that they are approved for and are similar to specified breakers, typically by a third party such as Underwriter’s Laboratory (UL).
Will a QO breaker fit in a QOB panel?
Plug on QO circuit breakers are only used for QO load centers, and can also be used for bolt-on panels. Bolt on QOB circuit breakers only work for NQOB, NQOD and NQ panel boards.
