Why my circuit breaker is tripping.

[Serg00]

Hi everyone, no sure this question should be in this forum, but im sure a lot of you will know the answer. I've set up a hot box to deliver food in my van. I've put a leisure battery 130ah and a inverter of 1000w continuous 2000w peak. between the battery and the inverter i've put a 100A circuit breaker. The hotbox head output according with the description is 810w, my circuit breaker at times trips, any idea why this is? TIA

100A MCB? Is that a typo?!

100A MCB? Is that a typo?!

I think its a 24V DC circuit breaker.

It's 12v 100a circuit breaker 12v - Recherche Google - https://www.google.com/search?q=100a+circuit+breaker+12v&oq=100&aqs=chrome.0.69i59l2j46i512l2j0i512l2j69i65j0i433i512j46i131i175i199i433i512j0i512.2139j0j9&client=ms-android-xiaomi-rvo3&sourceid=chrome-mobile&ie=UTF-8

Instructions for the inverter say it should have a direct connection to battery, it has fuses onboard (3 x 35A)

because the unit can do 2000W peak power, it is possible that for short durations it may be using 160A therefore a circuit breaker if it has a fast trip curve may not be the best thing to protect the cable with, if it were me i think i would use a 180A fuse.

Also note, it says it is not suitable for class 1 appliances. is the hot box class 1 or 2?
