Instructions for the operation of the master control switch for marine electrical appliances and devices:
Marine electrical distribution boxes are indispensable to the general control switch of electrical devices circuit. The installation of distribution boxes is related to the daily control of home circuits, so how to install them correctly is particularly important. Firstly, the box body of the distribution box should have no breakage, which can be divided into two types: metal shell and plastic shell. There should be transparent windows on open and hidden door panels. If an open assembly box is mounted on the wall, the length of the bolt fixed by expanding pipe bolts is generally the thickness of the bottom plate of the box, the thickness of nuts and washers, and the free distance of the buried depth. The power line of spiral fuse in marine electrical distribution box should be connected with the middle contact, the load line should be connected with the threaded terminal, and the ceramic plug fuse should be installed vertically.
