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).

A bridge rectifier may trip breakers if it is malfunctioning or drawing too much current, causing overload. Check for any short circuits or faulty components in the rectifier circuit. Additionally, ensure that the breaker is correctly sized for the rectifier's load requirement.
A 20 amp circuit breaker may get slightly warm during normal operation, but excessive heat could indicate an issue such as overload, loose connections, or a faulty breaker. If the breaker is excessively warm or hot, it should be checked by a qualified electrician to prevent any potential hazards.
Some common reasons for a circuit breaker to start tripping suddenly include overload (too many devices on the same circuit), short circuits (wires touching), ground faults (current leaking to ground), or a faulty breaker. Regular wear and tear on the breaker over time can also cause it to trip more frequently.
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.
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.
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.
