BEWARE the strict requirements for wire stranding with the Fuji MCCBs. ONLY stranded conductor with a SPECIFIC stranding are allowed. No ferrules. For an 80A unit, I had to get XHHW #4 to have 7 strands. THHN usually has too many strands nowadays and MTW is out due to fine stranding. For a 125A unit (this review) #1AWG THHN (-2, /THWN) was commonly available with the required 19 strands. Good luck bending it. If you used and 80A unit as MCB in a UL panel, your electrician will likely use wire (THHN/THWN/-2)with too many strands and therefore you'll break the rules for 'following manufacturers instructions' if anyone actually cares about this or actually follows the rules.
