The correct answer is NO the widthe of the opening is 11/16 not 3/4 as used on the 4/0 c** A: i had to use a dremel with a zip bit to make room for the 4/0 lugs **Q: Inverter Manufacturer says I need a 400Amp Breaker between my battery and low frequency inverter! 1-pole I assume?** A: 2 pole is safer, as it interrupts both cables. I have had 2 units of the 400amp single pole fuse open (no current) without ever tripping. I would not trust these units with anywhere near their rated current, which makes them useless as a breaker. Just a giant switch.... **Q: What does it mean when it says no short circuit protection at 12-32v? It sounds non-functional.** A: Correct. They are no good as actual breakers, better off with a knife switch and fusible links! ## Customer Reviews ### ⭐⭐⭐⭐⭐ Excellent product *by J***Y on January 30, 2026* Excellent product does the job as I bought another one a different product and it started on fire this is excellent a matter of fact they give you separators for the bottom and top in case of spark short or whatever this stop the electrical spark, short from hitting each other I mean this is excellent.
