Abstract: The power generator unit includes a container having a peripheral wall enclosing a power generating motor assembly. A breaker box is provided in an opening in the peripheral wall of the container, so as to have power outlet socket connectors accessible from outside of the container. An external electric circuit to be fed with electricity can be operatively connected to the power outlet socket connectors. Power inlet socket connectors are also provided in the breaker box, accessible from inside the container, to which the power generating motor assembly can be operatively and releasably connected. A breaker links the power inlet socket connectors to the power outlet socket connectors, to open the breaker box circuit should any excessive power demand occur. The breaker box is releasably bolted to the peripheral wall of the container, about the opening in which it is inserted. A pair of spaced-apart pockets are provided on the breaker box casing, being outwardly opened.
