Description of the difference between marine electrical appliances-distribution boxes and lighting distribution boxes:
The power distribution box and lighting distribution box of marine electrical appliances should be set separately, and the power and lighting lines should be divided in the same distribution box. Electrical appliances in distribution boxes should be installed first, on non-metallic or wood insulated electrical installation boards, and then tightened in the distribution boxes as a whole. Metal boards and iron distribution boxes should be electrically connected. Two levels of leakage in distribution box and switch box, rated leakage current and rated leakage current of protector, leakage operation time should be reasonably coordinated to make it have the function of hierarchical and sectional protection. When inspecting and repairing the distribution boxes and switchboxes of marine electrical appliances, the corresponding power switches at the previous stage must be switched off and disconnected, and the live operation must be strictly prohibited by hanging the power cut sign.
