This item was removed from a property in 2009. Originally it would have supplied night storage heaters, but these had been removed years before and replaced with socket outlets.
The label is from the original installation of storage heaters.
The black plastic section above the fuses has holders for spare cartridge fuses, although this unit is fitted with rewireable types.
The label fixed to the inside cover. This was supposed to have circuit details filled in, however this was not done. Someone has written 'Spare' on circuit 1, yet all of the circuits were in use.
The lower half of the label provides details of the required sizes of fusewire and fuses.
The neutral block can be seen just above and to the right of the main switch. The earth block is at the top left. The fuse next to the main switch can be of a higher rating than the others, hence the larger contacts. In this instance, all of the fuses were identical.
The black plastic item covers the cables above the fuses, and has clips where spare cartridge fuses could be stored. This was redundant in this installation, as rewireable fuses were used.
