The Electric Wire Relay is a new tool added in A16 as a part of the new Electricity game mechanics.
The Electric wire relay allows extending your electrical network further with a small cost to power.
The general flow is as follows: A ----- B ----- C
where...
A = Generator Bank / Battery Bank
B = Electric Wire Relay
C = Electrical component ex) spotlight, turret, etc...
Several electrical components can be connected to the Electric Wire Relay at the same time, which will put a heavier tax on the generator or battery bank, but is useful for wire management and to minimize the number of generator banks and battery banks.
The recipe above contains the Resources needed to craft the Electric Wire Relay for each level of the Advanced Engineering Perk. A higher level in the associated perk will decrease the crafting cost, saving resources.
