Hi just looking for sum validation on install. Have a 20amp dp switch on outside of bathroom that was used to power an old electric shower which has been removed. I have taken a spur from this switch to a 13amp unswitched fused unit (used the zone guide for placement of socket )this now powers electric towel rail. The supply for the 20 amp dp switch is str8 from the breaker box and its a 16amp supply (I used 1.5mm cable from old 20amp dp switch to fuse as heater is only 600w). I think the 13 amp fuse is too high a rating for the heater mayb drop to a 5amp? please any feedback guys
thanks
thanks
