[QUOTE="SPECIAL LOCATION, post: 28935, member: 250"] I think this is one where you may need to step back and just double check the bloomin obvious electrically... e.g. re-test the whole circuit from CU to Imm Heater.. R1+R2. Ins Res, Polarity. Correct cable size. Fuse rating. Volt drop. earth loop impedance If you can categorically say these are ALL correct there is nothing more you can do to make the supply any better? Have you checked the previous faulty heaters? i.e. is it just the element gone open circuit.. or is there an Ins-res breakdown? If the component is failing.. This is a manufactures warranty issue? All goods sold MUST be fit for purpose.. Sale of goods act 1979! ;) [/QUOTE]
