Inverter cables

[Manic]

I’ve a 800watt inverter which I want to fit for occasional use, pro not using all its capacity
It will be close to the leisure battery, within 0.5 metre, what size cables and fuse would I need.
Cheers

At maximum power you’ll be drawing about 80A so size for that (or a little more).
