Frequently Asked Questions (FAQs)

1. Why would a fuse block go bad?

A fuse block can go bad if the terminals or fuses become overheated, leading to burning or melting of the terminals or the plastic housing. This can result in the need for replacement of the fuse block and, in some cases, rewiring.

2. How do I know if my plug fuse is blown?

To check if a plug fuse is blown, remove the fuse from its holder. In some cases, you may need a small screwdriver to unscrew the fuse holder cap. Look at the fuse wire. If there is a visible gap in the wire or a dark or metallic smear inside the glass, then the fuse is blown and needs to be replaced.
