What is the largest stranded wire size accepted by MNEPV breaker terminal clamps?

16mm2 is fine, never tried bigger. The size of the terminal interior is 7mm x 7mm square. Sorry for the metric. (not really!).

Quite all right. I'm a yank, mate, but have lived abroad for going on 15 years. All I know is metric, anymore. :D

One Reseller's site states that the MNEPV single width breakers (up to 63 Amp rated),  accept #14 AWG through #6 AWG --  may need to select Circuit Protection,  then MNEPV ...  :

The double-wide MNEPV DIN Rail breakers accept up #2 AWG,  as stated on the MN Solar site:

Sorry,  here,  we are inch/foot/miles (apart from the "rest" of the world).

FWIW,   Vic

16mm2 would be about #6 AWG, iffin' I'm koreck, sir. :D

I just can't walk into an electrical supply store here and ask for anything in AWG. If I did - if they could speak English in the first place, they would look at me as though I were nuts. :D
