One of the diodes in the bridge may be shorted out. Use an ohm meter and check the front to back resistance on each of the diodes. It should have a high ohm reading one way (blocking) and low the other way (conducting).

Should a 20 amp circuit breaker get warm while in use?

Yes all breakers will get warm when in use. The full load current of the load flows through the device. Class A breakers current trip rating is rated at 40 degrees C. If in ambient temperatures higher that 40 C then the thermal trip rating lowers. Likewise if the ambient temperature becomes lower the trip rating increases. Sometimes breakers have to be rearranged in the electrical panel to keep high current breakers away from each other. The ambient temperature of adjacent breakers will raise a breakers temperature and cause needless tripping.


What can cause a circuit breaker to suddenly start tripping?

If the breaker trips when nothing is turned on it could be a mouse problem. If it only trips when certain lights or appliances are turned on one of them is probably the reason.If it trips when nothing is being turned on or off something is getting hot. You should then have qualified electrician look at it. Hope this is usefull.


What circuit breaker will interchange with federal pacific?

There is no breaker that will fit a FPE panel except a FPE. The breakers are still being manufactured and are available at Lowes and Home Depot stores, but they are expensive. The failure rate of FPE breakers is worrisome and if I had one in my home I would change it. Federal Pacific has been out of business since the early 80's The current breakers being sold at Home Depot etc, are NOT manufactured by Federal Pacific since that company no longer exists. They are made by aftermarket companies. The FPE problems are not associated with the newer products, HOWEVER, there may be issues with the older FPE panels themselves. It is important to inspect the panels carefully and see that there are no burned or arcing areas and that all screws on the bus bar are securely tight and the bus is not damaged in any way. The breakers must fit properly and SECURELY in to the panel bus bar and the panel cover must hold the breakers securely in place as there are no actual screws to hold the breakers in place. If the breaker fit is loose or sloppy, there is a problem.To clarify the answer to the question, there ARE other options to Federal Pacific or the aftermarket manufactured products. Federal Pacific has a "sister" company in Canada called Federal Pioneer. They are still in business and still being installed today. Although there was a recall on some of there breakers several years ago, there is not the notorious history to Federal Pioneer and they have continued to improve on the product designs.The Federal Pioneer breakers are available in Canada at very competitive prices. There are some sellers on ebay as well, but the shipping costs may be a bit high if you order one or two breakers only.Federal Pioneer is marketed by Schneider Electric of Canada. Check online for further details on the products and availability. You can also buy US made breakers manufacturers like "American" "Challenger" and "Connecticut" electric and a few others. Old, used or NOS "Federal Pacific" breakers have been determined to have high failure rates and should not be used as replacements. Existing Federal pacific breakers should be replaced even if they "appear" to be functioning normally. Keep in mind that the Federal Pacific panels themselves may not meet current codes or standards and should not be used for new installations or "expansions". Replacements of existing breakers are usually "grandfathered" in but once again, the breaker panels themselves should be checked out thoroughly for damages and ALL screw connections should be tight and secure and breakers should be secure in the bus bar. Covers should be securely installed. It may not be cost effective to replace ALL breakers as opposed to replacing the entire breaker panel itself. Weigh out the costs carefully as well as the problems and costs of replacing the entire panel. Keep in mind your "future needs" when making this determination.


Why does the 59n relay keep tripping the breaker?

The 59N relay may be tripping the breaker due to circuit overload, short circuit, or ground fault. Check for any faulty connections, damaged wires, or improper settings on the relay. Ensure that the relay is properly sized for the load it is protecting and troubleshoot any potential issues in the circuit.


What's being done wrong when the electric juicer keeps tripping the outlet?

The electric juicer may be drawing too much power for the outlet to handle, causing it to trip. Also, the outlet could be faulty or not providing the correct voltage. It's important to check the juicer's power requirements and ensure it's not overloading the outlet, and to have the outlet inspected for any issues.

What would cause a breaker to trip?

A breaker will keep tripping until the fault that caused it to trip is corrected. That's what it is designed to do. There's either a circuit overload or a short circuit. How fast the breaker trips can indicate how overloaded it is. If you are very close to the rating of the breaker you can actually trip it over time. If you are definitely over the breaker will usually trip instantly. If there is a short circuit you can usually tell that by how violently the breaker trips. If you have conduit you can hear the wires banging around in the pipe. A frequently tripping breaker may also be faulty and need to be replaced - breakers are designed to fail by tripping prematurely rather than by not tripping at all, as this is much safer. This is very often the case for breakers that trip at seemingly random intervals, often when very little load is being drawn.
