fuse board

[richard1971]

does anyone know what the blue 15amp fuse is for on a fuse board, i have got a feeling its for immersion heaters. any help please.

[raysparx1]

your feeling is probably correct,

5amp white = Lighting
15 amp Blue = Normally immersion or 1or2 sockets
30 amp Red = Cooker or Ring Main

Hope this helps you, Ray

It might be for the kitchen, because some houses have seperate 15-20 amp fuses fo the kitchen e.g. fridge, freezer, washing machine-handy, because if the ring main blows, the fridge doesn't go off.
Try taking it out and seeing what goes off in your house-be careful though, you may want to turn off the main switch first, remove the fuse and switch back on again rather than just pulling it out.
