One for the electricians or bright sparks excuse the pun in Thailand or elsewhere.

I am using an extension lead in a kitchen due to poor building design in a relatively new building. I am running it from one double socket obviously utilising one of those 2 sockets. Recently the extension lead keeps tripping so I am thinking of buying a new one with a larger capacity in terms of amps and watts. At the moment we are plugging into the extension lead various high power appliances one kettle, one microwave, one air fryer and one electric wok. We don't use them all at once but any 2 or more combined and it's tripping.

Although a higher capacity extension lead may work I'm worried about the potential draw from the wall socket, basically it frying and burning out and the potential of an electric fire starting at the wall socket. I am also concerned that the high draw on the extension lead even if it's capacity states it can handle the wattage may have the same effect with the extension lead catching fire.

So any advice much appreciated regarding whether the wall socket is able to handle multiple high power appliances all at once and also possibly using a higher wattage extension lead?

Worse case is getting an electrician in to install another socket (should have been done when it was built!) but obviously I would rather avoid this if possible.

Many thanks
