CONSTITUTION: Electric equipment 11 and an edge receiving spring 17 connected electrically with this are accommodated in a housing 12. The housing 12 is molded in a desired shape of plastic, being provided with a plug edge passage hole 16 at the lower part on one side of the outside. An edge receiving spring storage 12a is provided in the position fronting on the plug edge passage hole 15, and an edge receiving spring 17 is accommodated. The depth of the edge receiving spring storage 12a is made longer by a specified amount than the height of the edge receiving spring 17. The edge receiving spring 17 is made, being bent in roughly a U shape, by both opposite pieces 17b and 17b and a coupling piece 17c out of conductive elastic material, and fan-shaped parts 17d and 17d are made at the head. Hereby, a plug edge 4 linked to the conductive bar 3 is retained firmly by the edge receiving spring 17, and besides it can be easily inserted and removed.

摘要： PURPOSE:To enhance the assembling work by providing a power supply wiring pattern for a breaker on a wiring board in a box. CONSTITUTION:A wiring board 2 is formed into a thin rectangular plate having planes 201, 202 with bolt fixing holes 203 at four corners thereof. The wiring board 2 is arranged, closely to one end in the longitudinal direction, with a row of through hole main load terminals 204 and, in the center thereof, with two rows of through hole branch power supply terminals 205. The wiring board 2 is provided, on one side thereof, with a power supply wiring pattern. Since the branch breaker 4 is fed with power from a main breaker 3 through the power supply wiring pattern provided on the wiring board disposed in the box 1, no conductive member is required to be arranged in the box and thereby the work can be enhanced in assembly.

摘要： PURPOSE: To perform a wiring operation on the load side of a breaker while a mounting base is turned or the mounting base is removed from a distribution board in a state that a terminal hole for a breaker is separated from a terminal connecting piece by a method wherein the mounting base on and to which the breaker has been mounted and attached is moved along a guide member in such a way that the terminal hole and the terminal connecting piece can be inserted into and pulled out. CONSTITUTION: Breakers 9 are fixed, by screws, to a mounting base 12 on and to which guide-part coupling bodies 13 have been mounted and attached, and the guide- part coupling bodies 13 are inserted along opposite pieces 17, 18 from end parts 17a, 18a, on one end part, of the opposite pieces 17, 18 for guide parts 16. Then, the mounting base 12 is turned in a proper position so that load-side terminal parts 11 for the breakers 9 can be seen well, and it is fixed in a tightening part. In this state, the load-side terminal parts 11 can be wired and connected. The mounting base can be turned in a state that terminal holes and terminal connecting pieces are separated, or it is removed from a distribution board, and load sides of the breakers can be wired. As a result, the power-supply side and the load-side terminal parts for the breakers can be wired and connected easily.

摘要： PROBLEM TO BE SOLVED: To easily supply power to a common branch circuit, regardless of line linkage/line separation/maintenance in a line linkage system. SOLUTION: A switcher is provided with a power conversion part 2 that has a power converter 20 for converting a DC power into an AC power, a linked breaker 21 for switching between line linkage and system separation, after being inserted between a mains Lm which is connected to a commercial power supply AC and a power conversion part and a parallel-off switch 22, and a line linkage protection device 23 for performing system separation by driving a parallel-off switch, when a power failure and abnormality of a commercial power supply are detected. The power conversion part is a self-contained automatic switcher 3 of a line linkage system with a self-contained output part for outputting an AC power at system separation and is provided with first input parts T11 and T12 which are to be connected to mains that are connected to the commercial power supply, second input parts T21 and T22 which are connected to the self-contained output part of the power conversion part, and common output parts T31 and T32 for preferentially outputting an AC power from a second input part in comparison to the AC power from a first input part.
