abnormal operation
19.11.2
60335-2-6(ed.5)
Question:
During the simulation of the fault conditions, it shall be possible to switch off any energized hob element
The fault conditions are also simulated with all hob elements switched off, the appliance being supplied at rated voltage. If a pan detector is incorporated, a suitable vessel is placed on the cooking zone.
The hob elements shall not become energized.
Considering that it is stated by the wording of clause 19.11.2 of part 2- 6 "....off, the appliance being supplied at rated voltage"
shall all hob elements shall be switched off by a switch which is a part of the appliances and not a part of the supply installation, if any installation fuse or other protective device in the fixed wiring does not provide the necessary protection of the appliance?
Decision:
If during test of 19.11.2 the hob can not be disconnected by any of the controls of the appliance then it is not allowed to comply with the requirements of this sub-clause using external switches not provided with the appliance nor with the specific interconnection cables.
