Old, much older, various colours.
Three types of wire, 5 Amp Lighting, 15 Amp Heating, 30 Amp Power.
Replace fuses safely and easily - is that a suggestion or a fact?
1. Turn off main switch.
2. Pull out fuses in turn until the one with broken wire is located.
3. Remove old wire and wipe porcelain clean.
4. Insert a new langth of wire of the correct type.
5. Replace fuse, close box and turn on main switch.
This does not have any reference to replacing fuses easily or safely, so presumably it was likely to be difficult and dangerous.
The same values of wire and virtually identical wording. Made in England.
Most of the 5A wire is missing, and the card has been folded in half.
