Hi guys I know the wiring for an stc has been done to death and the many diagrams seem easy enough. My questions dont so much relate to the how part of wiring it up but the whys. I hate just doing things without a sound understanding of how things work whether thats wiring, brewing, pulling cars apart, etc. I have a reasonable amount of experience with wiring in cars but haven't done anything 240v and appliancy (definitely not a word). I want to make sure I've got this right using the below diagram.
Firstly Im not sure if this diagram is from the US and if we have slightly different colours but I think its right?
So we have the brown(ish) which is live?
Blue which is neutral?
and green which is earth?
Our stc power terminal has a live wire from the mains and a neutral wire back to the mains?
Our sensor terminal has both sensor wires in it, nothing from mains.
Both our heating and cooling has power from mains going in and a power line coming out and going to its respective plug?
Both our heating and cooling plugs have a neutral and ground wire running from the mains to the heating/cooling plug or from the heating/cooling plug back to the mains depending on how you look at it?
Hopefully someone can fill in those blanks with yes and no! I know theres a heap of diagrams out there but sometimes I find it helpful to spell out where each wire is going and what it is doing to get a sound understanding of how the unit is working, I havent seen a good detailed explanation of each wire and its function so hopefully (assuming the above is correct) it'll be helpful to others.
Cheers
EDIT: also as more of a general electrical question. The difference between neutral and ground is that neutral is the usual return for electricity back to the mains and the ground ensures that if a neutral or power wire hits the fridge and makes it live the current will travel through the ground wire and trip the breaker in the house preventing crispy humans?
