Need help identifying an electrical part

It's #8awg coming from the camper wiring. Nothing in the manual except that a manual resetting breaker is placed 18" from the battery, so it's been replaced...

Something missing here...you can't run one end to the positive lead of the battery and the other lead to chassis ground....

Any marking will be on the metal case under the red cover.
Number will be part of a short string not alone.

OK, what wire size is connected? Or what is the converter amp rating or model number.
Worst case go small with a 30 amp.

Ugg, there's nothing readable on the sides or back. I wonder if it's in the original paper work anywhere? Is there a common size?

Self resetting circuit breaker available at any autoparts store.
Trick is finding the amp rating on the side. Look for a 30, 40, or 50 as most common.
They don't always come with the plastic boot cover. Liquid brush on electric tape could substitute.

Although I prefer a manual reset breaker such as Bussmann Hiamp.

Probably a fuse or circuit breaker.
