Are Eaton and Cutler Hammer breakers interchangeable?

Cutler-Hammer and the Eaton family of products are the same and compatible. Part numbers have not changed, just the Eaton name has been placed on the product.

What kind of breakers are compatible with Cutler-Hammer?

What Breakers are Compatible with Cutler Hammer?

  • Low Voltage Circuit Breakers.
  • Medium Voltage Circuit Breakers.
  • High Voltage Circuit Breakers.
  • Thermal Circuit Breakers.
  • Magnetic Circuit Breakers.

What breakers are interchangeable with Eaton?

Eaton’s UL classified breakers are designed and tested to be both mechanically and electrically interchangeable with circuit breakers manufactured by General Electric, Thomas & Betts, ITE/Siemens, Murray, Crouse-Hinds, and Square D.

Is Cutler-Hammer same as Eaton?

Eaton acquired the Cutler-Hammer business through the acquisition of Cutler-Hammer Inc. in 1974. In terms of organisation, product and production techniques, Cutler-Hammer has been fully integrated into Eaton, adopting the Eaton Business System, a single system covering work processes, tools and tooling.

What is the difference between CH and BR breakers?

CH was originally Cutler Hammer (and now Eaton). BR has been rebranded a number of times, and was previously Westinghouse, Bryant, Cutler Hammer, and now Eaton. Me: I typically don’t install BR panels from scratch, everything is kind of cheap on quality.

What 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).

Can you interchange breakers?

Brand: Always install the correct brand of breakers in your breaker panel. While some breakers are interchangeable, many are not, even if they look the same. Replacing one brand of breaker with another can be dangerous, may void your breaker or panel warranty, and may lead to a failed electrical inspection.

Can I mix breaker brands?

Never place a different brand circuit breaker in a circuit breaker panel of a different brand. Contrary to the belief that they are all the same and will work in any circuit breaker panel, the fact is just the opposite. Circuit breakers may actually fit, but not properly.

What type of breaker is used in most homes?

Single-pole circuit breakers

Single-pole circuit breakers are the type most often found in homes today. They’re named single-pole because they’re designed to monitor the current of a single wire and trip in the event of a short or electrical overload.

How many receptacles can be on a 20 amp circuit?

ten outlets

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. Remember that your circuit, wire sizes, and outlets must be compatible to avoid overheating and electrical hazards.

How many outlets can be on a 15 amp circuit?

8 outlets

Technically, you can have as many outlets on a 15 amp circuit breaker as you want. However, a good rule of thumb is 1 outlet per 1.5 amps, up to 80% of the capacity of the circuit breaker. Therefore, we would suggest a maximum of 8 outlets for a 15 amp circuit.

What does QP mean on a circuit breaker?

The Siemens QP, QT, QAF, and QPF are the standard “interchangeable” plug-on type breakers used in loadcenters under several brand names including Siemens, Murray, Gould, and Sylvania to name the most common. It also fits most Midwest Power and Milbank Mfg metering equipment.

Are type QP and BR breakers interchangeable?

There are many brands and types that are almost identical. Even though it will fit and probably won’t be a problem, installing a Cutler-Hammer type BR in aSiemens panel that specifies type QP will be in violation of the National Electrical Code.

Can I replace a QP breaker with a QT?

Answer: You can use a Siemens type QP breaker in the same space as a Siemens type QT breaker, but these are 2 separate breaker types and not electrically interchangeable. The QP breakers are standard 1″ per pole branch breakers.

Are QP and Square D breakers interchangeable?

In many cases, a Square D type “QO” panel can accommodate Siemens Q-series circuit breakers, but this is not always the case. It is important to check with a qualified electrician or an electrical supply house to ensure that you can use interchangeable breakers in your panel.

What breakers are compatible with Square D panel?

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.

Who makes Siemens breakers?


The simple answer is, of course, Siemens – they make their own well-known and durable breakers. Siemens has been around for over 150 years in engineering and world history in general.

What does Square D mean on a breaker?

The Square D “QO” line of miniature circuit breakers is their best-known product line. 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).

What’s the difference between Homeline and 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.

Is Siemens better than Square D?

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.
