Be warned that in the next version a Reactor's output is doubled by default, therefore you may have to upgrade your cables /before/ installing the next IC version to prevent melting cables.
For example: if your reactor was outputing 70 EU each tick and you were using gold cables on it, the next version will output 140 EU each tick and melt the cable.
I just thought I'd post this before the next version to stem the torrent of "My reactor isn't working now, why!?!" posts ![]()
The reactor planner will be updated once the next IC version is offically out.
