The Mega Fuse holder I recently bought has a bolt centre to bolt centre on +/- 52mm not 50.8.
As a result the fuse will not fit on without either re-drilling the holes in the fuse or forcing the fuse down which I suspect will break the fuse ( i do not want to try this).
Since I only have one fuse holder I have none to compare it to.
Is this normal or are they meant to be exact?
