Multiplus 12/3000/120 Cable Size

The manual states 2 x 50mm for >5m.

Would 1 x 70mm be adequate for a 1m length?

@djwiscombe, is your 1m length figuring round-trip, or is that only a one-way measurement? If it's 1m round-trip, then I'd say yes, you could probably squeak by with that gauge, but if it's only a one-way measurement, then no, you should definitely stick with 2x50.

Thanks. Round trip is actually 1.25m. If I stick with 2 x 50mm what would be an appropriate size fuse? The manual states 400A but I assume each cable would need a fuse. Also, would I use one isolator for the two cables or an isolator for each cable?
