Schneider 3 phase Db

[cliffed]

just wondering your thoughts,just connected a 50mm Swa into the main isolator, Schneider ,Ati 9 isobar,it’s a 125 amp main switch,very tight.
To me it just don’t seem right,big cables for that switch.
Am I over reacting.

Have a read of the manufactures instructions. I haven’t looked but most are designed for a max conductor size of 35mm.

The 125A switch (SEA91253N & SEA91254) will take cable of 2.5 - 50mm stranded cable.

You can get bigger terminals that seat into the existing terminals if you need to use larger CSA cable.

Thanks,the other end goes into a 100 amp switch fuse,with lugs,just looks better,the info says it accepts 50mm,these cables are triangular,& a tight fit.

Usually a max of 35mm coarse stranded or 50mm solid as I recall.
