[QUOTE="WattsTheFrequency, post: 524024, member: 34744"] Hi, recently, after extended showers by family members the wylex box/ shower wire, which is outside bathroom in cupboard, started to heat up and set off the smoke alarm. We had it shut off and pulled the fuse. We decided to downgrade the gainsborough energy 2000x which, after taking off the cover appears to have 10.8 printed on the 'heat exchanger?'. We assume that is a 10.8kw, and that the wire to which it was connected is a 10mm wire, measures 4.1 ish on the calipers. We are downgrading to a redring 8.5kw. Question- Will the wylex 30A fuse, which didnt blow, still be suitable for protecting the circuit, and will the 'mcb?' at the consumer unit at the front door need upgrading/downgrading? Finally, old single light/heater unit coming out of bathroom, is the 5A fuse in the wylex box sufficient for a new 36w dimmable light, or do we need to downgrade it to a smaller amp? Thanks in advance. Photos provided. [/QUOTE]
