Hello all,
Quick question if i may...
Just been round to customers house, whose got no hot water from her vented hot water cylinder, top immersion.
Stats ok, but theres no power at the FCU, looks like shes on economy 7 as has two separate CU's for immersion and night storage heaters...which are working.
So i found the old unused FCU connected to the main CU and temp wired the immersion into that, this tripped the RCD, twice to be sure, so immersions blown...thinking about it, that prob wasnt the best way to test it...!
So will replace the immersion and connect it up as it was and wait and see if the economy 7 kicks in and heats it up.
Now if it doesnt, the customer is happy to bypass the Eco 7 and wire the immerison into the main CU via the old FCU i mentioned. As she hardly ever uses the hot water, lives on own 2 bed flat, elec shower.
The wiring into the old FCU in not happy with and has damaged taped wires, so i suggested would have to run new cable to CU, which would be easy.. can i do this, i know i am more than capable but is it legal?
Also im a bit confused why the 16a MCB didnt trip for the immersion when its blown? She said she didnt touch it? Unless it was a netural earth fault as the org immersion CU doesnt have a RCD.
Thanks in advance.
