Any electricians about? quick query

[DameEdnaBeverage]

We are fitting an exractor fan in the bathroom and instructions state that double pole fused spur with 3 amp fuse is required. Am having trouble locating a spur with 3 amp fuse. Can we just buy one with a 13 amp fuse and replace it with a 3 amp one?

DP is an electrician and he says yeah you can :)

Great - thanks for the quick response . Dh now has another query!
Can we use a 13 amp spur as the main on/off switch for a heated towel rail?. This will be part of an independent circuit which runs to garage (not the main lighting circuit). Am in a bungalow if this makes a difference. TIA.

He says yes, you just need to be careful which zone it is in in the bathroom (not that I know what any of this means, I just read your queries to him and he muttered yeah that's fine!)

The switch will be outside the bathroom in the hall.

Please thank your dp for the help and thanks for asking him
