Wylex Standard brown plastic fuseboxes
3 way fuse box
Very similar in construction to the 4 way and larger boxes. This one has three 15A fuses, and was probably used for night storage heating.
3 way fuse box - Internal view
This example was poorly installed. Note the excessive bare copper showing on the incoming tails (top right), the lack of sleeving on the CPCs (earth wires) at the top left, and the massive holes smashed out of the back panel.
2 way fuse box - External
This 2 way model appears similar on the outside, however note the cover fixing screws are right next to the on/off switch.
This box is rated to 45A maximum, yet has 2x 30A fuses installed. This supplied a cooker circuit, and all of the socket outlets in a kitchen. It is therefore likely that the total load would have exceeeded 45A.
2 way fuse box - Internal
Internally, there is only the frame which the fuses and switch are mounted to. There is no back plate or back box - the wall it was fixed to formed the back of the enclosure. For mounting on combustible surfaces, a separate flat panel was available to fix behind the frame. This was not used in this example, despite the box being fixed to a wooden board.
2 way fuse box - Frame only
The internal frame with fuses removed. The incoming connections are top left. Outgoing neutrals bottom left, earth top right above the fuses.
2 way fuse box - Exterior with fuse removed
Exterior view, with one fuse removed. As with the other Wylex examples, these are rewireable fuses. The fuse wire passes through the white ceramic block in the centre, and is fixed to the brass pins with small screws.
