I swapped my built-in oven today and when removing my old oven, I noticed that the plastic around one of the legs on the power plug had melted and stuck onto the socket. Took some effort but after prying the plug out from the socket, this is what I see.

Any idea what happened here?

Thanks guys. Just checked some articles online as well and yeah, it seems that it is likely due to arcing. Have to be very careful when I replace the plug to make sure it's well fastened, and that there is no exposed wire that may lead to arcing. This could have lead to a fire.. thankfully it did not.

Will need to replace the wall socket as well.. hopefully, no nasty surprises when I open it up.

Err.. sorry, I am unfamiliar with the terms you just used.. What are industrial type sockets? DOL to switch?

After what happened, I went around shopping for a new 15A plug to replace the above MK one. Can't seem to find a decent quality one. All seemed inferior to the MK plug. Tried searching at Homepro, Ace Hardware, etc. Any idea where to buy a good quality plug?

Thanks.. learning a lot from the sharing.

This is a neat solution, and I think the socket would fit into the hole in the wall nicely.

However, one problem.. how to conceal the cabling ah? The cable for the oven would be coming from inside the wall to the socket correct?

Well, I think I am going to give the 15A plug another try and monitor closely. Based on the power rating of the oven, a 15A plug should be able to support it.

After searching multiple shops, best brand I can find is this UMS plug (don't know much about the brand but it's an "old" brand, no?). It looks sturdy enough and the plastic quality seems decent. I can't even find the same MK plug in the market anymore. I wonder why. Could there be a flaw in that plug? Or perhaps it's too costly that most shops don't carry it anymore.

Bought myself a crimping tool.. and crimped the trimmed end of the wiring



Installed the wiring into the plug. A neat enough job you think?

Hmm, at the highest temp, my new oven can operate at 300 degrees C. Tested it for about 20 mins. There is no sound on the plug but it did feel somewhat warm to the touch. Should I be concern?

Total connected load: 3.6 KW

Oven Specs

Thanks, I think I screwed them down pretty tight. I will monitor further to see if it becomes unduly hot. When I did the test, it just feels warm. If some heat is to be expected, then I guess it's nothing to worry about. Maybe I will run the over at the top temp for an hour and then open up the plug to see how it is.

Based on my calculation, 15A should be just enough for the oven. I may be wrong though.. 3.6 KW at 240v would be 15A correct?

Argh.. I missed the information on the 16A connection rating. Thanks for pointing it out. Now, I am at a dilemma.. the 32A cooker point looks like an elegant solution but the wires have to be installed from the inside, so it's a no-go.

As for the commando plug.. it looks too "industrial".. plus I don't think there is enough space at the back of the oven to accommodate the large socket and plug.

Sifus, any other solution?

I came across these sockets on the internet that can support 16A but I think they are quite uncommon.
