Safety inspection of lighting electrical ready board is required

The safety inspection of lighting electrical ready boards is an important part of ensuring the stable operation of the power system and the safety of personnel. The following are the main points of safety inspection for lighting electrical ready boards:

Appearance and labeling: Check if there are safety warning signs such as "Beware of Electric Shock" posted on the door of the electrical ready board to ensure that the signs are clear and visible. At the same time, check whether the appearance of the electrical ready board is intact, without damage, deformation or rust.

Environment and Space: Ensure that there are sufficient safe passages and working spaces around the electrical ready board, and no flammable, explosive, or corrosive materials are piled up to prevent danger.

Sealing and Protection: Check whether the inlet and outlet of the electrical ready board are tightly sealed, and whether the gaps are sealed with fireproof glue, fire-resistant partitions, etc. to prevent water vapor, dust, or small animals from entering. At the same time, check whether flame-retardant materials are used to install screen protectors in the electrical ready board to protect the lines and wiring points from exposure.

Grounding and connection: Check whether the metal box door and metal box body of the electrical ready board are grounded and bridged with braided soft copper wire, and whether the connection is firm and reliable. In addition, check whether the incoming and outgoing wires of the electrical ready board are equipped with insulation pads or introduced with conduits to prevent damage to the insulation layer of the wires.

Internal inspection: Open the electrical ready board and check if the internal wiring is neat and there are no twisted wires. At the same time, check whether the control circuit identification is complete and clear, and whether obsolete safety performance poor knife switches are used.

In summary, the safety inspection of lighting electrical ready boards is a meticulous and important task that requires professional personnel to conduct regular inspections and maintenance.
