Hole (14b), the traversing section is close to set with the Shell of circuit breaker (1) outer wall；
Step 1.2, plug wire (5)：
Electric wire (5) overhang insulation crust is peelled off one section, then the metal-cored of electric wire (5) is connect via cable hole (14b) insertion
In line terminals (3), the avoiding misinsertion baffle plate (34) hides the wire connection cavity (14) positioned at the space at U-shaped slip terminal (32) rear
Cover, the electric wire (5) can be only inserted between the crimping plate (32b) and the fixing terminal (31) being located behind, adjustment drives spiral shell
Bolt (33) drives U-shaped slip terminal (32) to advance, and the crimping plate (32b) that is located behind and fixing terminal (31) are by the electricity
Line (5) is clamped；
Step 1.3, installs protective cover (4)：
The protective cover (4) is placed on Shell of circuit breaker (1) surface so that handle hole (41a) is right with the bolt apertures (14a)
Should, the electric wire (5) is inserted in the threading hole (44) and is fitted with the arc front shroud (45), through the handle hole
Be screwed onto the insulated screw (41b) in the bolt apertures (14a) and be fixed by (41a).
7. the application method of a kind of safety-type RCCB according to claim 6, it is characterised in that：Also include following
Step：The arc back cover is plugged on arc front shroud (45) rear.
8. the application method of a kind of safety-type RCCB according to claim 7, it is characterised in that：Also include following
Step：
Step 2.1：Lower handle (15), disconnecting circuit；
Step 2.2：The locking system (22) is pressed backward, and is pressed down on and is stirred bar (22d), drive the locking bar
(22c) is inserted in the locking hole (12a), and the test button (2) is locked at into closure state, and experiment loop of electric leakage is connected；
Step 2.3：When pushing handle (15) in other people maloperations, experiment loop of electric leakage obtains electric, trip gear action, rapidly by hand
Handle (15) is left behind again.
