Renovating an Inner West Terrace Kitchen? The Electrical Clearance Rules for Your New Cooktop

What are the electrical clearance rules for a new cooktop in an Inner West terrace renovation? AS/NZS 3000 sets exact rules for how close a powerpoint can sit to a cooktop and requires every cooktop to have its own isolating switch, rules that catch a lot of Inner West renovations out simply because the original terrace kitchen was never built to them. Add an induction cooktop, a new oven and a dishwasher to an older single phase switchboard, and the same renovation can turn into a capacity question as well as a clearance one.

1. The 150mm powerpoint rule that trips up a lot of terrace renovations

AS/NZS 3000 bans mounting a powerpoint or switch within 150mm of the edge of an open gas or electric cooktop. In a project home kitchen with generous bench runs either side of the cooktop, that is rarely an issue. In a typical Inner West terrace galley kitchen, where the whole run of bench space either side of the cooktop might only be 600mm to 900mm wide, it is a genuinely common design conflict, and one that is easy to miss when a renovation is planned around the look of the splashback rather than where the powerpoints legally have to sit.

This is one of the first things worth checking before cabinetry and benchtops are finalised, not after. Moving a cooktop by even 100mm or 200mm during a kitchen layout can be the difference between powerpoints that comply and a bank of GPOs that has to be relocated, with the associated cost of reworking cabinetry that is already built.

2. Why your cooktop needs its own dedicated, visible switch

Separate to the powerpoint clearance rule, every cooktop also needs its own isolating switch, positioned so you are not reaching across or over the hot surface to use it. This is a safety requirement rather than a convenience, since the whole point is being able to isolate the cooktop quickly in an emergency without putting your arm over an open flame or a hot element to do it.

On an island bench, which is an increasingly common request in an Inner West terrace's rear extension, this often means the switch needs to sit on an adjacent wall or in a nearby cabinet face rather than directly behind the cooktop itself, since there is no wall immediately behind an island to mount it on in the first place. It is worth deciding where that switch goes at the same time as the island's layout, not as an afterthought once the benchtop is templated.

3. Where your switchboard can't go

A separate but related rule bans a switchboard from being mounted directly above a stove, cooktop or an open water container, along with a handful of other restricted locations covered in detail in our guide to switchboard location rules for older Inner West terraces and semis. This comes up more often than you would expect in a terrace specifically, because older properties sometimes have the switchboard mounted in or near the kitchen to begin with, and a renovation that changes the kitchen layout can unintentionally bring a cooktop closer to an existing switchboard than the rules allow. If your renovation is touching the kitchen at all, it is worth having the switchboard's position checked as part of the same visit, rather than assuming it is fine because it has always been there.

4. Induction, double ovens and dishwashers: when the new load means a bigger circuit

A straightforward like for like cooktop swap rarely changes the electrical picture much. Where it does change is a genuine kitchen upgrade: induction cooktop, a new electric oven, a dishwasher and sometimes a rangehood with a more powerful motor, all added or upgraded in the same renovation. Each of those draws more current than the appliance it is replacing, and AS/NZS 3000's maximum demand rules mean the switchboard has to be assessed for the combined load, not just whichever single appliance is biggest.

On an older single phase Inner West terrace, this is a common trigger for a full switchboard upgrade, and occasionally a conversation about whether the property would benefit from a three phase supply, particularly if the renovation is also adding ducted air conditioning or EV charging in the same project. Our guide to switchboard upgrades for Inner West terraces goes through what triggers that decision in more depth, and it is worth having that conversation with your electrician before cabinetry is ordered, not after the kitchen is already built around a switchboard that cannot support it.

5. Knock throughs and galley layouts: the Inner West specific planning problem

A lot of Inner West kitchen renovations are not a simple reno in place, they are a knock through into the old dining room, or a new rear extension that moves the kitchen entirely. That changes the question from "does my current layout comply" to "where do the new circuits actually need to run", since cable routes that worked for the original narrow galley kitchen rarely make sense once the kitchen has moved or opened up. It also often means more circuits overall, since a larger, more open kitchen typically carries more fixed appliances and more powerpoints than the one it replaced.

If your renovation also touches original wiring behind plaster, cornices or ceiling roses, which is common in the Federation and Victorian terrace stock across Balmain, Rozelle, Glebe and Annandale, it is worth reading our guide to original wiring in Federation and California bungalow homes alongside this one, since the two issues often turn up on the same job.

6. Getting the sequence right: switchboard capacity before cabinetry, not after

The renovations that run smoothly are the ones where an electrician assesses the switchboard's existing capacity and the clearance requirements for the new layout before cabinetry is finalised, not after benchtops are templated and appliances are ordered. That one site visit, done early, is what tells you whether you are looking at a straightforward like for like circuit swap, a few new dedicated circuits, or a full switchboard upgrade, and it is far cheaper to find that out on paper than to discover it once the kitchen is half built.
