In Player Electricity System a network of devices is when a number of devices are connected together using cables. Networks of devices cannot be looped, meaning a power source cannot provide power to its self, for example if you have a large battery that connects to a wall light the output of that wall light cannot be plugged in to the input of the battery device.

This extends to longer networks of devices, if the large battery connects to multiple devices in a chain none of the those devices can be connected to the input cable socket of the large battery as this would create a looped network.

In the video below is an example of attempting to create a looped network in Player Electricity System.
