III. process flow

cleaning → wiring → installation → power on test run

IV. operation process

(I) cleaning

gently remove the remaining ash blocks in the box with a chisel, at the same time, remove other sundries out of the box, and then wipe the dust in the box with a wet cloth

(II) wiring

1 Switch Wiring Regulations: the phase lines of electrical appliances and lamps shall be controlled by switches. When wiring the switch, the wires in the box should be straightened out. After wiring in turn, the wires in the box should be coiled into a circle and placed in the switch box

2. Socket Wiring Regulations:

uneven coating

① single phase two hole socket has two kinds of horizontal and vertical installation. When horizontally installed, the right pole facing the socket is connected to the phase line, and the left pole is connected to the zero line; When installed vertically, the upper pole facing the socket is connected with the phase line, and the lower pole is connected with the zero line

② the grounding or neutral line of single-phase three hole and three-phase four hole should be above

③ when AC, DC or sockets with different voltages are installed in the same place, there should be obvious differences, and their plugs and sockets should be matched, and they cannot be used instead of each other

3. Wiring: leave a maintenance length (15-20cm) for the wires thrown out of the box, cut off the insulation layer, and be careful not to damage the wire core. For example, if there are terminals in the switch and socket, coil the wires on the corresponding terminals of the switch and socket in a clockwise direction, and then tighten the indenter. If there are plug-in terminals in switches and sockets, fold the wire core back and insert it into the round hole wiring terminal (when the hole is allowed to press the double line), and then press it tightly with jackscrews. Note that the wire core must not be exposed

4. Special attention shall be paid during wiring: in order to ensure safety and use function, all kinds of wire connections in the distribution circuit shall not be connected to other branches by means of jacketed crimping at the terminals of switches and sockets

(III) installation of switches and sockets

1 Switch installation regulations

① switches installed in the same building and structure should adopt the same series of products; The position of the switch should correspond to the lamp position; The opening and closing directions of the rocker switch of the same unit project shall be consistent, and the operation shall be flexible and the contact shall be reliable

② the installation position of the switch should be easy to operate, and the distance between the switch edge and the door frame is 0.15-0.2m; If there are no special requirements in the design, the height from the bottom of the toggle switch to the ground is 1.3m; The pull switch is 2-3 meters high from the ground, and the pull outlet should be vertical downward

③ the adjacent distance between pull switches installed in parallel shall not be less than 20mm

④ phase line shall be controlled by switch; It is strictly forbidden to install bedside switches in civil residences

⑤ for safety and convenience, switches for controlling lamps should not be installed above windows, mirror boxes, lockers and behind pipes in any place, and behind single doors. Waterproof porcelain pull switches or protective boxes should be used in dusty and humid places and outdoors; In inflammable, explosive and particularly humid places, switches should be explosion-proof, closed or installed in other places for control

2. Socket installation regulations

① the installation height of the socket shall comply with the design regulations. If there are no regulations in the design, the following requirements shall be met: the socket for concealed installation shall not be less than 0.3m from the ground, and the socket for concealed installation in special places shall not be less than 0.15m. Safety sockets should be used in children's activity places. When using ordinary socket, its installation height should not be less than 1.8m

② when there is a heating pipe above the socket, the distance between them should be greater than 0.2m. When there is a heating pipe below, the distance between them should be greater than 0.3m. If it is inconsistent, it should be shifted or treated technically

③ in order to avoid the interference of AC power supply to TV signal, there should be a distance of more than 0.5m between TV feeder pipe and socket and AC power pipe and socket

④ the floor socket should have a firm and reliable protective cover plate

⑤ in wet places, waterproof and moisture-proof sockets with good sealing should be used. Special sockets should be installed in places with inflammable, explosive gases and dust

3. Installation of switches and sockets:

① concealed installation: according to the wiring requirements, connect the wires thrown out of the box with the panel of the switch and socket, push the switch or socket into the box, align the box eye, and fix it firmly with machine screws. When fixing, make the panel straight and flush with the wall. Those with decorative caps on the mounting holes of the panel shall be installed together

② open installation: first put the wire thrown out of the box through the outlet hole of the plastic table, and then close the plastic table to the wall and fix it on the box or wood brick with screws. If it is open wiring, the hidden wire slot on the wood table should first be in the direction of the wire, and then fix it firmly with screws. After the plastic table is fixed, put the thrown phase line and ground (zero) line out of the wire hole of the switch and socket according to their respective positions, and press the wire firmly according to the wiring requirements. Then stick the switch or socket on the plastic table, align it, and fix it firmly with wood screws. Finally, cover the switch and socket

(IV) power on test run

1 After the installation of switches and sockets, shake the insulation resistance of the primary line by unit and household according to the system and make records before the power transmission test run

2. Power on and test run after the insulation resistance of each branch is qualified through shake test. Carefully check and patrol after power on to check whether the leakage switch is off, whether the socket wiring is correct, whether the panel is horizontal, whether it is polluted, etc. When checking the socket, it is best to use electroscope, which should be checked one by one. If there is a problem, it should be repaired in time after power failure, and records should be made

(V) finished product protection
