Copper Cable

Copper cables are Tier 1, the most common cable tier. They are only capable of handling Low Voltage (up to 32 EU-p), however, they suffer the smallest distance-related energy losses out of all the conventional cables, with insulated copper cables having even less energy losses.

They are also used in the creation of Electronic Circuits.

Shocks

If you move too close to the uninsulated copper cable you may get an electric shock which does damage to the player so it's best to insulate your cables.

Cable Efficiency

Cable type	Max packet	EU/b	Energy loss
Uninsulated Copper Wire	32 EU-p	0.3	1 EU/3.33 blocks
Insulated Copper Wire	32 EU-p	0.2	1 EU every 5 blocks
