10mm2 and up stranded here. I had to bend the wires around the terminals of the old Diazed pre-meter fuses. If I had used stranded I'd have had to use crimp-on connectors as you can't just wrap a stranded conductor of that size around a screw. I don't have the crimping tools, so I was glad I just had tot ake out my nose pliers. I have absolutely no problem working with 1.5 and 2.5 mm2 solid, even 4mm2 works ok, but 6mm2 is a bit hefty.
At least I didn't get shocked on 230V like the stupid sparky who hooked up our last meter feeder.
First thing we nearly didn't get the old feeders out of the meter, one of the screw heads had gone down the drain, but with a bit of hammering against the screwdriver we got it turning again.
OT for those who know or use the European cable designations: Do you use NYIF? In Austria it was used a lot before round NYM came up and the Germans still use it. However, it has become helluva expensive.
