my 2 cents before the fallout....
Green and yellow is a cpc.... circuit protective conductor.... it protects the circuit.
Heating controls, youve got unarmoured flexible cables crossing between joint boxes and valves, or thermostats or whatever....
Something happens and this flex gets struck with a pointy metal object. metal objects now shorting between a live cable and what should be a cpc...
Nothing happens. Circuit breaker doesnt trip, metal object now live.
Would you use the cpc as a live cable in a lighting circuit? Plastic switch, plastic box? No, i dont think so.
Using the cpc as a live cable in heating controls should never be allowed... identified or not. And it just reeks of a plumber wiring it up, not a competent electrician.
