Internally identical to the 4 way brown model, this one has a white painted wood frame and a cream plastic front panel.
Here, the fuse cover has been removed, showing the four fuses. All of these are 15 amp. This board was probably used for night storage heaters.
The painted wooden frame is clearly visible. Supply wires connected to the top right terminals, which have small plastic covers over them. These covers are often missing, which is dangerous as these terminals are live even with the main switch Off.
Note the plastic shields have a white section in the centre. This is made from arc-resistant material, so that in the event of a fusewire failing, the molten copper will not melt the plastic shield. These white pieces are often missing, which will result in damage to the shield when a fuse blows.
Neutral wires connect to the terminal block just above the first (right) fuse position, and earth wires connect to the top left brass block.
The switch and fuse assembly is made from moulded brown plastic, and is secured to the wooden frame with two screws.
