Right for a start if there's no seal has there been evidence of tampering? The question you should be asking yourself is are you prepared to take the penilties if you pull the fuse and it all blows up in your face. I work in and train the metering industry if there's a fault with the cutout I have seen evidence of what can go wrong in the way of bad burns etc. I would strongly recommend you contact your supplier who can arrange to get this work done for you.
