What does QO mean on a circuit breaker?

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 is the difference between Square D Homeline and Square D QO?

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 double pole 30 amp breaker used for?

The Square D by Schneider Electric Homeline 30 Amp Two-Pole Circuit Breaker is used for overload and short-circuit protection of your electrical system. This breaker is compatible with Homeline load centers and CSED devices. The ANSI-certified and UL-listed unit is rated for 120/240 VAC and 10,000 AIR.

What breakers are interchangeable with Square D QO?

Square D QO breakers are compatible with QO breaker boxes and CSEDs. Each ANSI-certified and UL-listed. Homeline circuit breakers are built with the same Square D brand quality you have come to expect at a price that makes them the best value in their class.

Are there two different types of Square D QO breakers?

Apparently, there are three types of Square D circuit breakers. These breakers are the Homeline, QO, and QOB breakers.

What breakers fit in a Square D QO panel?

Can you use a Siemens breaker in a Square D box?

The Siemens Type QD circuit breakers have been classified by UL for use in place of the Square D Type QO® listed circuit breakers in the Square D UL listed panelboards shown below.

Is Square D and Eaton the same?

The answer is simple: the same company owns the production rights for both Eaton and Westinghouse. Westinghouse had a low-voltage air circuit breaker line. The company sold the rights to this product line to Square D, which then sold it to Eaton Corporation.

Are QO breakers switch rated?

Switching Duty (SWD) Circuit Breakers

QO and QOB circuit breakers are suitable for switching 120 Vac fluorescent lighting loads. The switching duty (SWD) listing applies only to one-pole 15 and 20 A circuit breakers rated at 347 Vac or less.

Is there a problem with Square D breakers?

Name of Product: Counterfeit “Square D” Circuit Breakers

Hazard: The recalled circuit breakers labeled “Square D” are counterfeit and might not trip when they are overloaded, posing a fire hazard to consumers.

Are Square D breakers rated for 2 wires?

Square D and Cutler Hammer both manufacture breakers that are rated to accept two wires (double taps). When two wires are allowed a tiny graphic of two wires will be visible at the front or side of the breaker.

Can 2 wires go into one breaker?

When it’s NOT a defect: Double tapped wiring is ok if the circuit breaker is designed for two conductors. If a circuit breaker is designed for two conductors, it will say so right on the circuit breaker, and the terminal of the circuit breaker will be designed to hold two conductors in place.

Can you use a tandem breaker for 240v?

Unlike a double-pole breaker, which serves a single 240-volt circuit, a tandem serves two 120-volt circuits; it cannot be used to supply 240 volts to a single circuit.

Can 2 circuits share a breaker?

Yes, it’s fine to combine circuits onto one breaker, at which point they become one circuit.

Can you use a double pole breaker for two separate circuits?

Double-pole breakers have two hot wires that are connected by a single neutral wire. That means if there’s a short circuit on either of the poles’ hot wires, both trip. These breakers can be used to serve two separate 120-volt circuits or they can serve a single 240-volt circuit, such as your central AC’s circuit.

What is a piggyback circuit breaker?

A double circuit breaker takes the space of a single circuit breaker on a panelboard. Depending on local customs, they are called duplex, slimline, twin, half-height, half-inch, double and waferbreakers.
