Manufacturer says 15A fuse needed for 2.79kW oven

Earlier recommendations suggested as the oven can draw just over 12 amps, having a good quality plug that can handle heat over a longer period of time would be better than a bog standard plug.

I have run those MK tough plugs constantly at nearly 16A, for 3 days until the fuse blew. Very little damage to the plug, so I would say they are good for high loads (other plugs showed damage).

The MK plugs have those nice screw terminals, which give a good contact between the wire and terminal.
The toughplugs are large, which makes is easyer to get the heat resistant cable into.
Maybe the size helps with heat disapation.

Yes, having a 'good quality' plug is certainly desirable, particularly for a heavy load.

However,I don't think that 'tough plugs' (from any manufacturer) are any more electrically satisfactory (good quality') than the same manufacturer's 'standard' plugs - they are simply designed to be more resistance to mechanical damage due to 'rough handling', which obviously will not be the case with one supplying an oven.
