Abstract

The invention relates to a temporary main switch arrangement of an elevator, wherein a first switch (1) is in the electricity supply circuit (3) of the power tool and a second switch (2) is in the electricity supply circuit (4) of the elevator. The invention further relates to a method for fitting a temporary main switch arrangement into an elevator as well as to a method for modernizing an elevator. In the method for fitting a temporary main switch arrangement into an elevator a first switch (1) is fitted into the electricity supply circuit (3) of the power tool and a second switch (2) is fitted into the electricity supply circuit (4) of the elevator. In the method for modernizing an elevator a temporary main switch arrangement is fitted into the electrical system of the building between the distribution circuit (5) of the building, the electricity supply circuit (3) of the power tool and the electricity supply circuit (4) of the elevator; the electricity supplies are disconnected from the electricity supply circuit (4) of the elevator with the first switch (1); the electricity supplies to the electricity supply circuit (3) of the power tool is connected with the second switch (2); and modernization work of at least the electricity supply circuit of the elevator is performed.

Claims
