Hi,
I have a 6 years old Rowenta table top oven. The oven have both convection and grill function.
Last Christmas I used it to roast a turkey with the convection mode for about 4 hours without any problem. When I switched to grill mode to deep browning the turkey for the final half hour, the power trips after a while.
I have not been using the oven since then. Last week, when I try to use the oven again, both convection and grill mode trip the power supply a few minutes after turning it on.
As I was too busy with my work, I leave it to the repairman rather then Googling for solution and do the repair myself.
After a few minute into repair, he solved the problem. The oven can be use in all mode without tripping. I grilled my pizza for lunch.
Then it come to my thought what have the repairman done to stop the oven from tripping the power supply? Could it be that he removed the grounding of the chasis? I called him
He said the chasis is now bonded to neutral, rather then ground. So if there is current leakage, it will trip the power supply too.
Further thought, I asked what if there is a swapped in the power plug between the live and neutral or there is an error connection in the wall supply, then would the chasis be electrify with live ? He said yes!!
Is this code of practice by "grounding" the chasis to neutral acceptable?
I think there is a very high risk to take if there is swap in the polarity either at the wall supply or the extension plug or even the oven plug itself.
