ABSTRACT:
This invention involves a portable loadmake/loadbreak switch assembly or system which can be used to make or break high amperage power circuits. This switch is first connected in series with the circuit. When the current is running through the switch, the switch can be opened to break the current in a controlled manner. This switch includes two leads, each of which is provided with a special two part clamp. The first parts of the clamps of both leads are first clamped onto two eyebolt connectors along the circuit. This clamping is accomplished by rotating a portion of each first part in a clockwise direction. A second clamp part is then attached to the first part of the clamp on the loadside lead. Once attached, this second part allows the eyebolt to be loosened by rotating the entire clamp in a counterclockwise direction. Due to the second part of this clamp, the first part of this clamp's grip on the eyebolt is not loosened. Because the removed eyebolt is connected to the power cable, removing the eyebolt from its connection point on the circuit with the clamp results in the clamp holding both the eyebolt and the removed power cable. With the first lead of the switch is still connected to a eyebolt in the circuit, and with the second lead connected to the removed power cable, the switch is connected in series with the circuit. The switch can then break the circuit in a controlled manner.
