My DM would always say on leaving her home,l need to turn off the range meaning power to cooker. That's a pretty silly reason in this day and age because if maintenance needs to be done it can also be turned off at the circuit breaker. Re: Above counter isolation switch for induction cooktop? 19Apr 10, 2012 11:57 pm I was always told that the isolation switch was a incase of fire safety type thing. An induction cooktop for the purpose of the as/nzs 3000 clause I would say is a heating element, it heats by induction, but saucepan on stove catch fire still producing heat! Also if you read AS/NZS 3000:2007 you will find that active and neutral are both live conductors and as such you would need to open both to satisfy the clause and a normal switch in a powerpoint will only open one wire. If it was me, as an electrician, I would not use an extra switch in a power point, and I would think it was needed! However, you could ask the regulating body in your state, energy safe Victoria in Victoria, if a switch operating a contactor which failed open would be acceptable, then the normal extra switch could operate the coil in the contactor which could be mounted in an enclosure hidden somewhere. 2 Re: Above counter isolation switch for induction cooktop? 20Apr 11, 2012 8:51 pm Quote: "-it heats by induction, but saucepan on stove catch fire still producing heat!" I just can't believe these isolation switches have anything to do with the contents of saucepans on stove tops (induction hot plates) catching fire. The last thing I would be thinking of in this situation would be to turn off the isolation switch. My actions would be very much directed at what the hell I am going to do with this fire in the saucepan. The need for an isolation switch must have some thing to do with (as above) "A circuit for fixed or stationary cooking appliance having an open cooking surface incorporating electric heating elements....." So...If the source of heat is regarded as an issue why isn't there a need for an emergency gas shut of valve for gas cook tops? Induction cook tops just do not have an open cooking surface incorporating electric heating elements. I just don't get the need for these isolation switches. Seems very much like a belt and braces approach particularly when safety switches (at the switchboard) are there to isolate when any electrical issue arises. cheers barkly Any electricians here please help. 1) Will the Fan need separate switch to ON/OFF/Speed eventhough it comes with Remote 2) how about… 0 1224 My daughter and son in law are about to start building, they are having a 600mm induction cook top and 900mm oven.
