[QUOTE="SPECIAL LOCATION, post: 520527, member: 250"] A basic concept that may help you understand is that electricity ALWAYS generates some heat as it flows through a circuit.. Items consuming more power will generate more heat than lower power items.. (e.g. Table lamp, TV, Computer, Phone charger consume minimal power compared to Showers, Cookers, Heaters etc..) All cables should be a suitable size and all cable joints should be mechanically sound to prevent this heat from causing damage to either the cables or the equipment. If you have a poor joint with a loose joint connection.. although the appliance(s) may work, over the course of time the joint can become damaged due to excessive heat building up... So your type of symptoms where something works.. then a joint overheats and stops working.. then cools down and starts working again.. Are not uncommon.. BUT as highlighted they can become a serious fire hazard if not attended to. The best course of action is to get it professionally checked ASAP. :coffee [/QUOTE]
