Home devices are connected in parallel and not in series.

parallel circuit .
A parallel circuit is different in many ways from a series circuit: 1. In parallel, the voltage across all the devices connected is the same. 2. If a fault occurs in any device connected in parallel combo, then it has no effect on the operation of the other device. 3. In series circuit the current flowing through all the devices is the same while in case of the parallel one the voltage across all the devices is same.
See the answer below.
A parallel circuit
In a parallel circuit, voltage is the same across each branch of the circuit. This means that the voltage remains constant regardless of the number of devices or components connected in parallel.
Parallel for main circuits and series parallel for lighting circuits.

The system can support 4 devices.
Dependable voltage; and you don't need to have all devices on or off simultaneously.
