4/0 AWG (107mm2) should do the job then?  Grin



Would have the inverter cabled up by now but the supplier messed up and sent me two runs of black instead of black & red. Sad

This stuff is a bit tricky to shape, going to get some plastic conduit saddles so i can hold it in shape when i hang it on the wall.

Why conduit saddles as opposed to cable cleats ?

If you are doing short runs, it is worth pre-forming the shape of the cable first, then marking the sheath and orientation of the crimps before fitting them. You may find it difficult to twist the cable from one end to the other once the crimps are fitted. I have recently bought one of the chinese/chocolate 8-ton hydraulic crimp tools from Flea-buy for 20 or so. You may need the next size up for 105mm. (It will do for hobby use, but would only last 3 days in professional use).  Bigger units are available for bigger cables.
