Place immediately on the Boiler Engine’s right with the shafts meeting. Electrical cables can connect on any of its six faces. See Electricity and batteries.
Opening its controls shows a matching illustration and name in the left panel. See Machine interfaces.
This is the electrical generator in a boiler setup. It supplies 800 W only when its left shaft directly meets the right shaft of an eligible running boiler; both machines must face the same direction. A cable, pipe or gap between the machines prevents coupling. The boiler can still burn fuel without this connection. See the complete generation route.
