[QUOTE="helotaxi, post: 2725945, member: 550915"] Its not the body of the holder that's the issue. The solid chunk of brass can handle a TON of current. It's the little spring contacts that make the connection with the fuse that are the issue. The spring connection is fairly high resistance and has a small contact patch. The result is a lot of heat generated if you pull too much current through that connection. There is a reason that no reputable company markets a MAXI fuse larger than 80A, the fuse holder contacts can't handle more current than that. I know what a MAXI fuse is. I use them in my current setup in a Stinger Expert block. Even that block which is a 3# lump of brass has contacts only rated at 80A. ATC fuses are only rated to 40A. If you want bigger you need to step up to a fuse with a screw down wide area connection, not a quick change spring contact. [/QUOTE]
