Your best bet would be to contact GE directly - or a nearby GE Wholesale Electric Supply distributor. GE, like all electrical panel manufacturers have made many variations of panels to comply with ever-changing code requirements. If it is very old, you may need to locate a used electrical part supplier - or change the entire panel.
Hi - I'm an electrician and can help you with your question.
A BR2100 circuit breaker is a 2 Pole 100 Amp (for the part number "BR2100", the "2" indicates the number of poles and the "100" indicates the amperage) circuit breaker. It can be installed in a single phase or three phase 120/240 VAC system panel that specifically lists the BR series breakers as acceptable for use.
A BR260 A BR2100 circuit breaker is a 2 Pole 60 Amp (the part number BR260, the "2" indicates the number of poles and the "60" indicates the amperage) circuit breaker. It can be installed in a single phase or three phase 120/240 VAC system panel that specifically lists the BR series breakers as acceptable for use.
It is not possible to have a BR2100 rated for 60 amps, 1 or 3 poles, or a BR260 rated for 100 amps, 1 or 3 poles.
It is not permissible to install any circuit breaker brand or type in any panel that does not specifically include it on a list of acceptable circuit breakers.
Circuit breakers are designed to carry 80% of the amperage rating. To determine the load a circuit breakercan carry, multiply the circuit breaker amp rating by 80%. This means that if you need to supply more than 80 amps, you cannot use a 100 amp circuit breaker. A higher rating is required. A BR2110 would be acceptable for loads greater than 80 amps, but less than 88 amps because the formula above says: 110 amp x 80% = 88 amps.
To determine the breaker size, determine the load (by measuring with a meter or obtaining amp rating of the load from the data plate) and multiply it by 125%. Using the same numbers in the example above; assume an 88 amp load. 88 amps x 125% = 110 amp circuit breaker. The 60 amp breaker is acceptable for up to 48 amps because 60amps x 80% = 48 amps. A 48 amp load needs a 60 amp breaker because 48 amps x 125% = 60 amps.
A tripping circuit breaker is an indication of an overload. You say there is no load on the breaker - how are you making this determination? Are you using an amprobe or some other meter?
A circuit breaker with NO load shouldn't ever trip. Likewise a circuit breaker carrying up to 80% of of the current it is rated for shouldn't trip either. Circuit breakers that carry more than 80% of their load will trip - if the load remains connected long enough. This is called "duty factor" or "service factor" The greater the load is in excess of 80%, the less time that the breaker will carry it before tripping.
An example of a 100 amp breaker with different loads on it (this 100 amp value was chosen for ease of doing the math):
80 amps - never trips 85 amps - trips after 48 hours 90 amps - trips after 16 hours 95 amps - trips after 8 hours 100 amps - trips after 4 hours 105 amps - trips after a few minutes 120 amps - trips after a few seconds 150 amps - trips instantly
This is only an example to show how a certain circuit breaker might trip under a load less than the rating stamped on the body or handle.
A circuit breaker that trips with no load or a load equal to or less than 80% of its rating is most likely defective. You need an amprobe or ammeter for amp readings. If the load is found to be 80% or less, there may be an issue of harmonics that is causing the tripping. You'll need to have special equipment and qualified persons to check harmonic problems. Most harmonic problems occur when the loads are not linear device (transformers). Examples of non-linear devices are "switching" (or solid state) power supplies like those in computers.
I hope this helps and good luck. Please rate my reply. Thank you.
The breaker that feeds the panel and the wire are what determines the rating. The panel has to be at least as high as the breaker. It can be more, and no problem.The problem I see is that the wiring is undersized for the 60 amp breaker. You should have #6 wires or change the breaker to a 50 amp. If that is not enough for your load, you must change the wiring. It also depends on the type of wire. THHN will have the largest amperage, but if it is TW, it will be lower. Rule of thumb would be #10-30 amp, #8-40-50 amp, #6-50-60 amp, #4-70-90 amp and #2-95-135 amp. There are other factors, such as derating etc. but if you wanted to increase to 100 amp, I would run #2 thhn. Hope this helps.
First the part number QOC20U100F is a flush mount panel cover. The panel you have is most likely a :QO116M100. No you cannot replace the breaker as the bus in the panel is only rated for 100A. In addition I believe this is a 20CKT panel. If you're gonig to a 200A service you'd probably want more spaces than that. Home Depot and Lowes both carry 200A panels with starter set of breakers at reasonable price. The QO panels are a bit better than the Homeline
Here is a link to manual for their panels. : http://static.schneider-electric.us/assets/DIGEST/load-centers.pdf
The total panel ampacity should be rated first by your load, then by the main breaker. if you are feeding it out of another box, it will probably be a double 100amp. In that case you will probably use 100amp SER cable.
Yes the maximum size branch circuit breaker that will fit in a residential load center is 100 amps. I would recommend that you calculate the amount of power that you need the sub panel to handle, then add any additional loads you may need in the future. Hopefully this is less than 100 amps. I would recommend that you check with your local electrical inspector to make sure your installation meets all local and national codes before proceeding with the install.
I dont mean this to sound arrogant. but if you have to ask you might be best to have a professional to do it. the wires coming into the box will be hot without being able to pull meter off of house to disconnect. the panel has to come off and many are different
