A plastic case fusebox with two cartridge fuses. Both fuses rated 15A.
The two fuses are identical, both 15A. The holders just pull out of the main unit and contain a replaceable cartridge fuse.
The front cover is fixed with a single screw, located between the fuses and the main switch. The cutout section on the lower edge is where circuit wires entered.
The plastic shields are fixed with a single screw. The main feed wires connect just above the 'on/off' label. Circuit wires connect to the top of each fuseway, with neutral at the bottom right (2 terminals) and earth at the top right (5 terminals).
This was also used for heating, although in this case on a permanent unrestricted supply, as the heaters were normal convector types which were just switched on as required.
The plastic shields have blue coloured washers behind the fixing screw.
Circuit wiring connects to the top terminal of each fuseway, the 2 way neutral bar bottom right, and the large earth bar top right.
These boxes could alternatively be fitted with rewireable fuses, the only difference being the fuseholder itself.
It is fixed with a single screw, which rather unhelpfully meant that a tool was required to replace the fuses, even though the fuses themselves just clip onto the holders with no tool required.
