The invention concerns an adapter for conversion of three- phase current to one-phase current, said adapter including a three-phase plug 1 and at least three one phase boxes containing devices that are electrically connected to each. To create a simply produced adapter the protective grounds and zero phases of the one-phase boxes 3 are combined with metal strips 4, 5 so that the protective grounds are together and the zero phases are together. The protective grounds coming from the three phase plug 1 are connected to a common contact point 6 for all one-phase boxes 3 produced with metal strips 4 and the zero phases are correspondingly connected to a second contact point 7 common to all one-phase boxes 3. <IMAGE> |
