Can 15amp plug work on 13amp extension lead?

Yes, a 15-amp plug can work on a 13-amp extension lead, but it’s not recommended. While the plug will fit, the extension lead is rated for a maximum of 13 amps, which may not safely handle the potential load of a 15-amp device. This could lead to overheating or a risk of fire. Always use plugs and leads that are compatible with each other for safety.
