Tripping 20 amp fuse

[Hartzel]

I have a 20 amp fuse that trips every now and then that controls the converter and few plugs. What could cause this?

Hello @Hartzel, can you provide more details such as what the fuse is for? Is there any activity you can correlate to the fuse tripping such as usage of an electric device, air conditioner, etc.? It could be an overload of the circuit, could be bad wiring, obviously anything that the fuse is designed to protect.

It is a 20 amp fuse that controls the converter. May go month then trip. Nothing consistent..

Are you using multiple things at once? fridge while using air conditioning? Space heater while also using fridge and a hair dryer? Etc

Hartzel, what does the blown fuse look like? Is the element completely gone from the middle or is it just kind of melted and just laying on the bottom of the fuse? When the element vaporizes (disappears) that generally means an overload, and if the element is laying in the bottom (melted) that usually means a high load. There are auto resetting breakers that can be installed in place of fuses.

You say "tripping a 20A fuse". Is this a fuse or a circuit breaker of concern? Fuse's usually don't go bad. They are good or no good and are not resettable. A circuit breaker, if hot or elevated temperature, will trip before its rated current value. Check and tighten all connections going to the circuit breakers.
