Because a central heating model does not have any electrons travelling through wires but have water. If a wire broke in a electric circuit , then if you're not going to turn off the circuit you would get electrecuted. In a central heating system, if it would break water will leak and nothing will hurt you or anything and you won't get electrecuted.
Generally we use electric switches to put on or off the light,fan,computer,music system,etc.An electric switch is a device that is used to open or close an electric circuit.when we open an electric circuit the flow of electric current inthe circuit stops and when we close an electric circuit an electric current flows through it.
The switch may be off or there is a break in the wire that stopped the electron flow in the circuit
If your circuit breakers are in the garage, they would be in a electrical panel (a metal box mounted on a (usually) outside wall, with the electric meter on the outside. The circuit breakers can be either just below the meter on the outside on opposite it inside the garage. It would usually be very close to where the electric connection to the house is. The electrical panel and breakers are not necessarily in the garage.
Neutral would refer to some object or circuit which has the same electric potential as the relative object. A "neutral bar," would mean a conductor which has no electric potential. If your body has no electric potential, then the potentials will equal, and no energy will be transferred.
As a symbol, a screw would represent technological sophistication.

What symbol would represent a chlorine ion that has ionized to have a stable electron configuration?
A backbone?

You think probable to the chemical symbol of an element.
In a science lab. 2. In an electric stove, or an electric blanket.

Rectangles
A symbol to represent happiness would be bluebirds (happy birds...),flowers,a beautiful scene, smiley face, rainbow...........Anything that makes you happy.....
If there is an electric short, the resistance of the circuit would be zero. So you can use an ohm meter to test it.
