THE START
Whether it is an industrial robot engineer or a PLC application engineer, they are all inextricably linked with electricity . A robot engineer with a monthly salary of tens of thousands, who dares to say that he has not installed electrical cabinets and connected wires?
If you want to learn the wiring of the distribution box , it is enough to read this article!
Working conditions and site preparation
1. The cabinet is installed. 2. The air switch, wiring wires, and cable ties in the box have been prepared and meet the design drawings, distribution box installation requirements, and construction procedures; the guide rail installation must be horizontal and match the operating hole of the cover plate.
open installation
1. When installing the air switch, first pay attention to the position of the mounting hole of the air switch on the box cover, and ensure that the position of the air switch is in the reserved position of the box cover. Secondly, when the switches are installed, they should be arranged from left to right, and the reserved position of the switch should be a whole position.
2. The reserved space is generally placed on the right side of the distribution box. There is a complete space reserved between the first row of main circuit breaker and sub-circuit circuit breaker for the first row of circuit breaker wiring.
wire selection
1. The neutral line color should be blue. 2. Lighting and socket circuits generally use 2.5mm2 wires, and the number of air switches connected in series with each wire shall not exceed 3. The air-conditioning circuit generally uses 2.5mm2 or 4.0mm2 wires, and one wire is equipped with a circuit breaker. 3. The neutral line between different phases must not be shared. If the first yellow wire from phase A is connected to two 16A lighting circuit breakers, then the neutral line of the circuit breaker equipped with phase A can only be equipped with these two circuit breakers. , After the distribution is completed, it is directly connected to the zero line terminal .
first zero line
4. The wiring between the main circuit breaker and each branch circuit breaker in the box generally goes to the left, and the wiring out of the distribution box generally goes to the right.
5. The wiring in the box should be straight and without any cracks. The wires should be tied with plastic ties. The tie sizes should be appropriate and the spacing should be even.
6. The wires should be bent uniformly, and there should be no dead bends to prevent damage to the wire insulation and internal copper core.
Second row zero line
5. The wiring in the box should be straight and without any cracks. The wires should be tied with plastic ties. The tie sizes should be appropriate and the spacing should be even.
6. The wires should be bent uniformly, and there should be no dead bends to prevent damage to the wire insulation and internal copper core.
Wiring
1. Phase A wire is yellow, phase B wire is green, and phase C wire is red.
2. Lighting and socket circuits generally use 2.5mm2 wires, and the number of circuit breakers connected in series for each wire should not exceed 3. Air conditioning circuits generally use 2.5mm2 or 4.0mm2 wires, and one wire is equipped with a circuit breaker.
Air conditioner A phase wiring
3. The neutral line between each wire distributed by each phase of the main switch must not be shared. If the first yellow wire distributed by phase A is connected to two 16A lighting circuits, then these two lighting circuits will be switched on once. The side neutral line is also only distributed from the primary side of these two circuit breaker and directly connected to the neutral line terminal.
4. The wiring between the main circuit breaker and each branch circuit breaker in the box generally goes to the left, and the wiring out of the distribution box generally goes to the right.
Circuit breaker B phase wiring
5. The wiring in the box should be straight and without any cracks. The wires should be tied with plastic ties. The tie sizes should be appropriate and the spacing should be even.
6. The wires should be bent uniformly, and there should be no dead bends to prevent damage to the wire insulation and internal copper core.
Circuit breaker C phase wiring
Wire bundling
1. The wires should be tied with plastic ties. The size of the ties should be appropriate and the spacing should be even, generally 100mm.
2. After the tie is tied, use pliers to cut off the unused parts.
