2. Lighting and socket circuits generally use 2.5mm2 wires, and the number of open wires connected in series for each wire shall not be greater than 3. Air conditioning circuits generally use 2.5mm2 or 4.0mm2 wires, with one wire with a gap.

3. The zero line between different phases shall not use * * *. For example, the first yellow line matched with A connects two lighting gaps of 16A, then the zero line matched with A can only match these two gaps, and will be directly connected to the zero line terminal after matching.

4. The wiring between the general open space and each open space in the box generally goes to the left, and the outgoing line of the distribution box generally goes to the right.

5, wiring in the box should be straight, can not have grain connection phenomenon, wire should be bound with plastic tie, tie should be the right size, uniform spacing.

Extended data distribution cabinet operation requirements

First, the power distribution cabinet is the normal operation of the ship's power distribution center and equipment, and any irrelevant personnel shall not pull the switch on the board.

Second, after the start of the generator set, the power board speed-up switch should be used to manually accelerate slowly until the generator enters the normal working state, and the voltage and frequency reach the specified value before switching on and sending.

Three, after the power distribution panel into the power distribution state, shall not be arbitrarily pull the power panel up switch, unless an emergency air switch locking switch shall not be used.

Four, generator parallel operation should be strictly in accordance with the requirements and regulations of parallel operation, and should pay attention to the reverse power (countercurrent) and parallel operation failure phenomenon.

Five, stop the generator load should be cut off first, and then no-load parking, not directly stop with load.

Six, shore power, should first cut off the shore power switch, and then check the correctness of the wiring and phase sequence, after confirmed, before the implementation of shore power conversion, it is strictly prohibited to run with load.

Seven, the power distribution cabinet should be cleaned and maintained regularly, so that the equipment is always in good working condition.

Eight, when the generator is working, the engineers should concentrate their thoughts and operate carefully when operating the switchboard to prevent accidents, otherwise they will be investigated for personal accident responsibility.
