hi all need a bit of advice on an immersion heater fault.
attended site yesterday to an immersion heater circuit that blew the fuse 15A (3036) as soon as it was inserted.
tested insulation res on cable (1.5t/e) and very low reading so this morning run a new 2.5t/e in up to double pole switch in airing cupboard.
connected up and everything worked fine until i went out to the garage where cu is and there was a very fishy smell and fuse holder hot to the touch.
when i removed the fuse there is burn marks to the back of it but fuse wire still intact.
system is tt with 3036 rewirables and in good condition.
immersion heater reading 15.7 ohms across terminals but looks like it wil be a bugger to remove and inspect.
all advice welcomed please
