Hello,

Your mod is really great but I would like to suggest you a new config (disabled by default of course) to make some changements on your mod:

1. Make that a machine destroyed by a pickaxe returns the exact machine, all the time; (idem for cables)
2. Make that a Low Power machine connected to a High Power doesn't explode but just doesn't function; (you can also add a kind of smoke effect)

These ideas are from IndustrialCraft2 Classic Edition (for 1.6.4 and 1.7.10) created by I can't memorize his name, where these settins was added, but disabled by default.

The second idea could also be coded for the normal game. The smoke effect appears if a Low Power machine is connected to a High Power, but the machine would explode only if used (ex.: an Electric Furnace with a ore inside, in process of smelting), but if the machine is not in function, it just emits smoke. A machine recharging itself doesn't count as an use. Like that, you have a little chance to disconnect the machine before an explosion. For the first idea, lost the insulation of a cable when you remove it, it's really tough.
