[QUOTE="Timotei, post: 554401, member: 25363"] Thanks binky....the 13A fused switch had definite signs of overheating (running at close to 13A for close to 10 hours a day) but had not melted as I've often seen when an immersion heater has been wired through a FS, so I would definitely want to swap out for a 20A switch. If we are saying that the 3kW heater can not overload, then surely no need for the 13A fuse anyway? How is Sunny Plymouth today? I'm a South Hams boy (and long suffering (until last season) Argyle fan) stranded up here in Shropshire. [/QUOTE]
