When my ceiling lights stop working I convinced myself to have a look at it before calling an electrician. So after turning off the main fuse box I manage to unscrew the ceiling lights down and found out that the blade fuse rated 15a has been melted. Is it OK and safe to change the fuse with a higher rated one, if so what ampere is suitable? The lights has got four 12v 20w GU4 bulb and 220v main supply.Please help. Thanks

Only use a fuse of the same or higher voltage rating and the same or lower amperage rating.

Thanks.what can you say about the melted fused? Is this normal for a blade type fused?

Fuses melt when they see an overcurrent condition. Sometimes just age and fatigue can cause them to fail, but sometimes a lamp that fails can cause a short circuit, causing the fuse to open (melt).
