The Electrical Engine requires 6 EU/t to produce 2MJ/t, and must be connected to redstone power to run. You can connect it to any voltage without causing it to explode, and it will not take the maximum available output per tick. For example, you may connect an MFSU as a power source, and it will only take 6 EU/t to produce 2 MJ/t. However, you still have to use the correct cable type to handle the maximum output packet size from the source or your cable will explode.
The Electrical Engine will automatically shut down when overheating and reactivate itself after cooldown.

The Electrical Engine can be upgraded with Copper, Bronze, Tin and Iron Electron Tubes placed on a Circuit Board. If you break an Electrical Engine with a Circuit Board in it, the Circuit Board will be lost. In the GUI of the Electrical Engine you need to take your Soldering Iron and click the upgrade to take it out. The upgrade will then be placed in an empty slot of your inventory and you can place your Soldering Iron back in your inventory.
The effects of these tubes are:
|Type of tube||Effect (Max stack)||Change in input EU||Change in output MJ||EU:MJ ratio (Normal 6:2 = 3:1)|
|Copper||Choke(1)||-2 EU/t||-1 MJ/t||4:1 (Worst)|
|Tin||Boost I(2)||+7 EU/t||+2 MJ/t||13:4 = 3.25:1|
|Bronze||Boost II(2)||+15 EU/t||+4 MJ/t||21:6 = 3.5:1|
|Iron||Efficiency(1)||-1 EU/t||No change||5:2 = 2.5:1 (Best)|
Note that the ratio listed is assuming you only use one tube.
