Jay see 1997 GU build up

[10G]

Now I'm pretty sure that this is wrong and now is the time to fix it.

I have a 10 blade fuse box and a 120amp breaker with 4 awg cable.

You can see that everything is pretty close.

At the most I'll be running 2 fridges, a freezer, the little 12v oven (while the car is driving)and then it's lights and charging points. If I was to assume 10 amp per slot = 100 amp breaker. I know that I'm not at 10 amp for every slot, so will a 70 amp breaker work and what size cable should I be using.

While I'm on the topic, sort of..

Is this worth it. It pwm not mppt.

I'm pretty sure in the past I used a similar setup protecting a similar load and my main cct breaker was only 60 amps.

And as BrissieBoy said, keep all your fuses as close to the battery as possible.
