WARNING

• Never replace a fuse with one that has a higher amperage rating.
• A fuse with a too-high amperage could damage the electrical part and cause a fire.
• On no account should fuses be repaired (e.g. patched up with tin foil or wire) as this may cause serious damage elsewhere in the electrical circuit or cause a fire.
• If a fuse blows repeatedly, do not keep replacing it. Instead, have the cause for the repeated short circuit or overload tracked and fixed.
