Browse Forums Kitchen Appliances 1 Jan 17, 2011 10:11 pm In our new build we are having a wall of cupboards on one side of kitchen containing an electric wall oven, along with integrated fridges, and microwave. There is no spot within 2 metres in that room to install a wallplate to incorporate an isolation switch. A google search found a statement that AS3000 2007 states an isolation switch is not needed except for an exposed electric heating element. (ie electric hotplates and similar only, so my oven and gass hotplate are now exempt). Can someone confirm this? Also can hardwired appliances (ovens and dishwashers) be installed on offpeak circuits like water heaters?

Smart meters have now changed the way the power companies bill so the circuit wouldn't matter. I also believe wall mounted ovens must be hard wired now. As for the isolator, they are handy if you are able to work on your own appliances, but you need to be certified Electrician (A grade I believe) to do that any way. My father in law has isolators for all his appliances as there was one already there he just removed old isolator and installed multi way unit. He had to remove his oven the replace a wiring loom that got chewed by a possum/mouse. Switched off the isolator, slid out the oven and carried it to garage. Then came back in and cooked a stir fry on cook top. Very handy, but only if you can work on the appliances Re: Wall Oven isolation required? 3Jan 18, 2011 4:48 pm 71monaro In our new build we are having a wall of cupboards on one side of kitchen containing an electric wall oven, along with integrated fridges, and microwave.

For memory AS3000:2007 amendment 1 chapter 4.3 covers this, wall ovens don't need the isolation switch. Don't quote me on it just yet, I'm home and my books at the office. I'll be back Monday if you don't have a difinitive yes or no by then. 71monaro Also can hardwired appliances (ovens and dishwashers) be installed on offpeak circuits like water heaters? Do you mean as in the "J" tariff meter for the hot water service? Best to read your power providers connection amd metering rules for this but I'm sure off-peak is for hot water only (unless this has changed since 1991 in Victoria). (For those who may not of seen it, it was common for houses to have two kilowatthour meters and a time clock fitted. One meter run 24 hours a day, this did the lighting, power and airconditioning circuits whilst the second meter was switched by the time clock for heating of hot water usually from midnight to 6.00am. If you needed more hot water during the day, you turned the switch from NIGHT to DAY to use day tariff power from the main meter to heat the water and then you turned it back) Re: Wall Oven isolation required? 4Jan 19, 2011 9:10 am Help me too please. I have moved into my new house 2 months ago minus the Ilve induction 90cm cooktop because the electrician has just realised that it draws 10,8kw. He has allowed 63 amps per circuit but has decided it needs 3 phase to the cooktop and classes it as a commercial unit. The isolating switch needs to be in arms reach of the cooktop according to regulations. Here ****** the problem and stand off. I refuse the put the ugly isolating switch on my expensive splashback which is not there yet. Ilve will not exchange for a smaller 60cm and gas was not provided to the kitchen. BIG MISTAKE TO HAVE THIS INDUCTION TOP! Can isolation switches be hidden in cupboards? Hi Chippy, no there isn't, gave it a really good look through and literally opened everything and checked all edges as well. Hence the question, just hoping someone would… 2 2077 My daughter and son in law are about to start building, they are having a 600mm induction cook top and 900mm oven.
