Energy, Cables and Voltage

Power travels in packets. Each tier has a maximum size:
mp;2LVmp;r 32 · mp;2MVmp;r 128 · mp;2HVmp;r 512 · mp;2EVmp;r 2048 EU/t.

mp;4Careful:mp;r a machine receiving a packet that is too big explodes. Basic machines are LV.

Cables (max EU/t · loss per block):
Tin Cable 32 · 0.2
Insulated Copper Cable 128 · 0.2
2x Insulated Gold Cable 512 · 0.4
4x Insulated HV Cable 2048 · 0.8
Glass Fibre Cable 8192 · 0.025

Uninsulated cables (Copper Cable, Gold Cable, HV Cable) shock you — insulate them with Rubber. Tin (Insulated Tin Cable) is harmless. Cables that are too weak burn out.

The EU-Reader shows charge, grid and throughput of any block.
