I am currently running with IC2 dedupe enabled and I have noticed that the Industrial Blast Furnace and Industrial Electralyzer appear to be the only machines I can make explode by providing too much EU.

I have tried the following machines connected to an IC2 MFSU and none of them explode:

Industrial Centrifuge
Implosion Compressor
Vacuum Freezer
Industrial Grinder

They work as normal and when I measure with an EU reader it seems they just draw their rated EU as indicated by their tooltip.

If I use an Industrial blast furnace with an MFSU it explodes as expected but only when connected via an IC2 cable. If I connect it directly to the face of the MFSU it behaves as above where the blast furnace will just draw its rated 128EU/t from the MFSU.

The Industrial Electralyzer exhibits the same behavior as described above for the Industrial Blast Furnace.

Industrial grinder just exploded upon being placed.

You need to use IC2 power source and IC2 cables to have machines exploded.
