Immersion Heater cut out and wiring

[VWWM 1]

Hi Quick question as I can’t seem to find the regulation in the BBB.
Carried out an EICR and found the load for the water tank was wired in 2.5 t and e.
On testing the circuit I couldn’t see a thermal cut out. Could you help me out with the appropriate regs regarding these observations.
Thanks in advance

554.2.1 for the cut-out.

not sure if there is one for the cable if no signs of thermal damage.

That thermostat has a built in cutout.

Thanks it’s off a dedicated circuit via a FCU and timer so will just change for a DP SW and add 2.5 heat resistant cable with some clips, as the existing is Miles too long and wrapped around the shelving and the tenants camping gear!

Nice 1 ?

is it that blob between the 2 terminals on the stat. on the pic it looks more like a screw head, but googling the stat, it does say cut-out is in it.

Blob was the element connection from the thermostat. ? thanks guys

Yes it's a recessed button.

problem is how do you know if it works? can't test as the stat will cut out long before the cut-out.

How would you test any thermal cutout?

blowlamp. oops that's a wet-pants' solution.

I will recommend to client a plumber checks it as the tenants complained it’s a bit unreliable.

That is 2.5mm t&e connected to the element, dont like that should be butyl flex.
