I wouldn't do it with circuit breakers.. John Hervey www.specialtauto.com -----Original Message----- From: supermattthehero [mailto:supermatty@xxxx] Subject: [DML] Replace fuse block with circuit breakers? I replaced a fuse today in my car and realized then that my fuse block holds my fuses very loosely. I can nearly pull them out with a single finger. After looking around for replacement fuse blocks, I thought, why not replace them with circuit breakers of the same size?
