Hello. I want to give electricity to machines like, electric furnace, macerator, extractor etc. I put the MFSU, and i connected it with a solar panel. It gets power just fine, so it has like 50.000, but now I would like with this power to give electricity to my machines, but I can't figure out how. I guess I need some cable to put it in the orange dot, and connect it to my machines, but It doesn't seem to work at all. Usually the machine explodes (not the MFSU). What I am doing wrong? I am new to tekkit so I don't know much things, What cable would I need? Also would I need anything else or I can directly connect MFSU to my machines?
