Class L 1600 Amp Fuse

[petersonra]

So I did some number crunching and came up with a full load current of 1203 Amps.

Most of time when I get into those lofty ranges I have used MCCB (not that it happens all that often), but this time around I am thinking a class L fuse would be just the ticket. So I go to find a 1600 Amp Class L fuse block. It appears no one makes them. They make 1600 Amp class L fuses but not fuse blocks, at least none I could find.

Are you supposed to make your own fuse block? Or are these things intended to be bolted directly to bus bars.

One manufacturer says they can make them, however they are UL Recognized so must be installed as part of listed product.

Why not just a 1600A fused switch? It wouldn't likely be a regular safety switch type due to the current, you might have to go to a bolted pressure switch. https://www.eaton.com/us/en-us/cata...pringle-bolted-pressure-contact-switches.html

Getting kind of elaborate for what I want.

I am thinking I can break the load into three chunks and use three sets of 500 a class j fuses. I have to think this through though. Or maybe 4 sets of 400 A fuses.

Or maybe I tell the customer it is their problem.
