How to replace a Bryant GFCB120 Circuit Breaker

If you have a Bryant load center, you can use other breakers in it, including the Eaton GFCB120 GFI since several companies unified their design. The GFI (ground fault interrupter) or GFCI (ground fault circuit interrupter), same thing, may be required for a device you are installing, such as bathroom, kitchen or outdoor fixtures.
The Eaton series includes very clear installation instructions, but if your problem is that they are missing, then all you do is install the breaker in a open slot in the breaker panel, but you have to attach the neutral [white] wire differently. On regular breakers, the neutral goes right to the ground lug in the panel. With a GFI breaker, it goes through the breaker, and then is connected to the ground lug.

Main breaker doesnt stay turned on

Tripping of the main breaker could be an indication of a short or an overload. To check for an overload you will need an amprobe to test the amperage load on the breaker. Turn all the secondary breakers off. Attach the amprobe by clamping it around one power wire. Turn the breakers on one at a time and check the reading of the amprobe. Most breakers will handle about 80 % of the breaker rating before tripping. If it trips below this point the breaker may be weak and will need to be replaced. If the amprobe pegs out at any time and the breaker trips the secondary breaker that was last turned on probably has a short in its wiring somewhere. Cuasing the breaker to trip. Underground wirng that has gone bad can sometimes take a while to trip the breakers so if there is any underground feeders it may be more difficult to track down a short. If the problem is an overload check both hot wire to see if the load is equal if the load is a lot higher on one leg than the other switching some circuits to the lower side may help. If the total load is just too high you may have to increase your service to a larger size. Hope -this helps

We just started noticing that, when running the dryer, there's a smell coming from the breaker box. It smells like something electrical burning. The circuit breaker for the dryer was a little warm,...

A burning smell from an electrical panel is never a good sign. You did what a lot of people will do, and have the same results - the problem won't go away.

The circuit breaker relies on the mechanical squeeze pressure of its metal clips to maintain solid electrical contact with the panel's bus bars. The problem is likely due to a poor connection between the circuit breaker and the panel board bus bars. Over the years, the load presented by the dryer has heated those points, weakening the metal clips, changing the metal conductivity in some cases due to pitting and arcing. Changing the entire panel is probably not required - especially if there are other unused spaces for a circuit breaker to be installed.

If this is the case, I would remove the new QO230 circuit breaker and install it in a previously unused space in the panel, instead. The bus bar here should be undamaged (since it was never used before), as would be the new circuit breaker contact clips. The damage has been done to the bus bars at the original location, and that space should never be used again. The same holds true for the old QO230 circuit breaker. Install SQD blank plates in the panel cover to keep fingers from getting inside.

Next, a current reading should be taken with an ammeter or amprobe. A 30 amp breaker should have no more than 24 amps on each wire connected to it. If yours is more than that, something is wrong. If it is not more than 24 amps, measuring the voltage at the breaker and the dryer plug should be done as well. The voltage at the plug should not be more than about 3% lower at the plug.

If there is no more room in the panel, a secondary panel can be installed adjacent to and fed from the original panel, space permitting. Move the dryer circuit to the new panel and any two adjacent poles of circuits (for a 240 volt feed). The dryer circuit breaker space will be abandoned and the two additional poles will be fitted with a new QO circuit breaker to supply the new panel. Your electrician should do this work for you. This is "permit required" work and must be inspected for your safety.

I hope this helps and good luck. Please rate my reply. Thank you.

Have A non digital amprobe ultra clamp.does not read when using clamp.Can you help.It's real old.The probes work ok.has A thumb wheel with different volt,amp scales.On the side of the scale is...

When the voltage measuring is OK, are you sure you are on the correct position for Clamp AC current measuring.
If you have some positions for DC current they may be through probes, but can not be by clamp for such an old amprobe.

If every thing other is OK, but you can not use Clamp for AC current, you may have problem in the current transformer in the clamp.

I hope that this will be helpful, because I don't know exactly how your device looks like, but some people rank such an answer with 2 thumbs, which means useless.

Plug In Carbon Monoxide Alarms, do they get old or out of date?

Hopefully you still have the instructions that came with it. It will tell you a date that you should replace the unit,how to test it and regular maintenance procedures. My unit says to replace it after seven years.

Generally CO monitors have a test button on them. If it tests and it is within the manufactures recommended lifespan, it should be fine. Just check your backup battery every month by hitting the test button and vaccum the intake vent every so often.

If you don't have the instructions, you should be able to go to the manufacturers website and find this information.

Photocell and circuit breaker

Hi, Here is my clarification of the instructions for you. The photocell must be protected by at least a 10 amp circuit breaker. The photocell may be installed next to the light fixture. ( not the breaker). Good Luck, this should Fixya!
