Replacing circuit breakers in your electrical service panel but not sure which ones to use? Normally you would just go to the panel and look up the specified breakers the manufacturer has listed. Maybe you’re trying to save money or can’t find the part you’re looking for and now you’re looking for options. Here is the dirty truth about interchanging circuit breakers.

 

Specified, UL Classified / Interchangeable Circuit Breakers

Specified breakers mean the manufacturer has tested the breakers in the panel and listed them to be used in that panel. You have probably noticed “UL Classified” and interchangeable circuit breakers around the market. These are breakers that have been tested in panels that they are approved for, similar to manufacturer specified breakers. Essentially, they are a different brand from the panel manufacturer but are still in their electrical service panel.

There’s a little controversy about UL Classified and interchangeable breakers. Some manufacturers have no problem with Classified breakers while others do. Manufacturers like Square D warns against the use of Classified and interchangeable breakers. They site the National Electrical Code (NEC) Section 110-3(b), which states that using breakers not listed or labeled is a code violation. Their argument is for public safety drawing evidence from past accidents due to the use of Classified breakers in their panel. The images below are damages to a Square D load center from using a classified breaker.

Square D insists that this is a code violation which will result in their warranty void. They went as far as to say that you may lose your license. However, Eaton and the Underwriters Laboratory (UL) would disagree.

Public safety is a factor, which is why a third party, like the UL, lists suitable manufacturer replacement breakers (UL Classified). These breakers meet UL and NEC code regulations. UL has stated that people must adhere to all manufacturer supplied instructions. Moreover, UL also stated that Classified breakers can be used for their approved panels. (Source: UL Marking and Application Guide Panelboards). On the note of warranty void, manufacturers cannot void their warranty if the replacement part has proven to be safe by a third-party, for instance UL (Magnusson-Moss Warranty Act).

 

Compatibility Chart

There are charts that show what circuit breakers are interchangeable. For instance, the chart below shows an example of a cross reference of Type CL 1″ breakers that could be interchangeable for panel installations. You can check under the panel column for compatible Eaton UL Classified breakers.

Conclusion

In short, the manufacturer’s specification is always a good first choice. Otherwise, just replace the same type of existing breakers in the box. Manufacturers would want to specify their own breakers for use in their panelboards for obvious financial reasons. However, remember you have options with UL Classified breakers like the chart above. Some electricians use Classified breakers for obvious reasons, whether for price, availability, or convenience. But which ever circuit breakers you go with, make sure to install them safely.

How to find out what breakers are compatible with my panel?

Match the letters

If the breaker has the same "Type" letter markings on it as are listed on the panelboard label, you're fine. Number suffixes on the type marking (such as QAF2 vs QAF and MP-AT2 vs MP-AT) are used to denote a revised type of breaker that is still compatible with the original and can be used in place of it, so they don't matter in your case.

10kAIC is fine

The Siemens/Murray line of breakers comes in three interrupting rating options -- 10kAIC, 22kAIC, and 65kAIC. The larger options are more costly due to extra internal equipment needed to break bigger arcs, and are only necessary in commercial work where larger services and feeders capable of higher fault currents are found.

In addition, in a main breaker panelboard such as yours, a breaker with a lower rating can be used because it receives a higher series rating by way of being "backed up" by the panelboard's heftier main breaker.

what breakers are compatible with siemens

Your safest bets are Siemens QAF, QPF, QT, and QP. The most recommended way to know what breakers are compatible with Siemens, check your panelboard’s manufacturer’s manual.

But what if you no longer have it or the instructions are illegible? You can use the previous broken Siemens breaker as a reference when buying. You can also opt to request new documentation from the supplier.

Read on to know the exact reasons why these are the most practical routes to take.

Why Should You Stick to the Official Documentation?

This is because there’s more than a handful of ways that you’ll end up with the wrong breaker otherwise. Is it risky if you go this route?

Unless you do modifications that raise the chances of overheating, probably not. However, would you be willing to put up with the constant worry that you’re using something faulty in your home’s electrical system?

Always remember that just because you’re able to get a lightbulb to turn by touching two wires together doesn’t mean they’re compatible. I’m going to stress it again: only use Siemens-compatible breakers.

It’s Best to Choose Circuit Breakers Made by Siemens

siemens-compatible-breakers

I said the safest bets are QP, QT, QPF, and QAF breakers because they’re manufactured by the brand itself. Did you know that Murray and Siemens are pretty much the same company? Their breakers even use the same parts, but they are not certified to be interchangeable.

Furthermore, I need to make it clear that many manufacturer’s manuals will only recommend products made by the brand for use as a Siemens main breaker. It’s also important for you to know beforehand that not all breakers made by the brand could be suitable for your panelboard.

You may notice that other brands are more lenient when it comes to their breakers’ interchangeability with other companies. Unfortunately, I wouldn’t say Siemens panelboards are just as manageable based on the documentations I’ve read through.

What About UL Classified Circuit Breakers?

UL classified breakers, especially those made by Eaton, are an exception to what I said. Why? They’re designed for interchangeability with Siemens breakers, simply put.

You can confirm the information by reading a Siemens breaker compatibility chart, but that’s entirely up to you. Sometimes, I refer to the Siemens circuit breaker compatibility chart prepared by Relectric sometimes when I’m verifying the information I need or can’t find the information proof required. However, I’d take official documentation over this any time.

A Siemens QP breaker compatibility chart or manual may say that their circuit breakers fit into other load centers made by other brands. General Switch, Westinghouse, Murray, Challenger, Arrow Hart, and General Electric serve as good examples of such brands. However, that doesn’t always mean that the breakers they produce are also compatible with Siemens panelboards.

Take the Time to Test Your Breaker

siemens-breaker-compatibility-chart

Even if you’re close to 100% certain that the breaker replacement you buy is compatible with the panel, I’d still suggest you test it first before using it. Check whether it fits the slot intended for it. Believe it or not, some subcontractors even cut breakers with a saw just to make them fit. While that might work, you’ll essentially be playing with fire, literally and figuratively, if you decide to do so.

That’s exactly why I prefer to know what circuit breaker is being placed in my panelboards. The service you hired may be making “adjustments” that could lead to overheating. I’m not saying it’s common practice, but I’m also not ruling out the possibility since I’ve encountered these issues both offline and online before.

For more tips on how to test the circuit breaker in your home, I recommend you check out this official video created by the brand:

It discusses troubleshooting mostly but there’s a good portion that explains how Siemens circuit breakers work and how you can test them, too.

Conclusion

To sum it up, you can rely on a number of Siemens circuit breakers cross reference sites online for knowledge, but, to me, they’re not as conclusive and veritable as anything recommended by the brand through its official manuals.

So if you’re going to ask me about which first step to take any time you need to change a breaker, it’s always going to be, “Get your hands on those handy manufacturers’ booklets.”

Hope you like this guide on what breakers are compatible with siemens? I’d love to hear your experiences in the comments.
