# Explain this electrical problem

## Recommended Posts

How comes the sum of all the pumps and gas filters on the right finds its way behind my transformers on the left ? I thought the purpose of electrical transformers was to separate circuits ?

1. Transformers are 1kW consumers.
2. You have 3 1kW transformers on one circuit.
3. Therefore you have 3kW consumption potential on one circuit.

A counter question: why do you have mixed wire types on one circuit?

Well then i dont understand what a circuit is. Since each transformer has its own in cable and out cable I thought i was good to go. But because they are all linked to the battery cable it doesnt work ?

This system only needs less than 2Kw, Can you explain how i pool the 3 generators + batteries + transformers the right way please ? A screenshot would help immensely

If the wires are directly touching they are all on one circuit. It doesn't matter how you branch it off. Because conductives are sharing the circuit with heavi-watt, your heavi-watt line is 2kW max.

Here is one solution. Bubbles needed to train her construction skill anyway.

Batteries are not transformers. Absolutely ALL the wire on your generator circuit MUST be heaviwatt wire.

@Xiombargdei, I think you’re assuming that electricity is modeled more realistically than it actually is.

It’s easy to imagine that electricity does pathfinding. That is, what matters is how much electricity should logically move from point A to point B along a length of wire. If there’s a wire leading to a single 1 KW transformer, logically only 1 KW’s going to travel along that wire, right? No matter what else is connected to that wire upstream.

That’s not how electricity works in Oxygen Not Included. A set of connected wires is considered a single entity, regardless of shape or electrical paths. If you have 3x 1 KW loads connected to a grid, every segment of wire in that grid experiences a 3 KW load, regardless of where it is in relationship to that grid. Even dead-end wires experience the load. If there’s an overload, the game selects one wire segment at random to damage, position doesn’t matter at all.

The only way to isolate one wire grid from another is a transformer. That’s what they do, electrically isolate the output grid from the input grid.
