How to Plan Kitchen Circuits for a Renovation

A kitchen can look complete on the day the stone benchtops and appliances go in, then become frustrating the first time the kettle, toaster and air fryer run together. Knowing how to plan kitchen circuits before cabinetry is ordered helps prevent overloaded outlets, inconvenient power points and costly changes after the walls are closed.

Kitchen electrical planning is not a DIY design exercise. In the ACT and NSW, electrical installation work must be carried out by a licensed electrician, who will assess the installation, applicable requirements and the capacity of your existing supply. Your role is to explain how the kitchen will be used. A good electrical plan then turns that information into safe, practical circuiting and outlet locations.

Start with the kitchen you will actually use

Begin with the appliance schedule, not the floor plan. List every fixed appliance proposed for the finished kitchen: cooktop, oven, rangehood, dishwasher, fridge, microwave, coffee machine, integrated bin or boiling-water unit. Then include the portable appliances likely to share the benches, such as kettles, toasters, sandwich presses, mixers, air fryers and slow cookers.

This matters because kitchens have a high concentration of heating appliances. A toaster may only run for a few minutes, but a kettle, microwave and air fryer can draw substantial power at the same time. The circuit arrangement needs to suit realistic simultaneous use, rather than assuming only one appliance will ever be switched on.

Think through daily routines as well. If one person makes breakfast while another unloads the dishwasher, where will appliances sit? Will a coffee machine live in a dedicated appliance cupboard? Is there an island used for food preparation, laptop charging or entertaining? These decisions affect both the number and placement of outlets.

Separate fixed appliances from general kitchen power

A well-planned kitchen usually divides electrical loads into two broad groups: dedicated circuits for particular fixed appliances where required or appropriate, and general-purpose circuits for benchtop outlets and smaller loads. The exact arrangement depends on appliance ratings, manufacturer instructions, the existing installation and the electrician’s design assessment.

High-demand appliances commonly need individual consideration. An electric oven, induction cooktop and dishwasher should never be treated as an afterthought. Some equipment may require its own circuit, an isolator in an accessible location or a particular connection method. A rangehood, integrated microwave and boiling-water system may have their own installation requirements too.

General benchtop outlets need careful planning because this is where temporary high-load appliances gather. Rather than relying on one double power point near the sink, allow for the parts of the bench where people will actually work. Adequate fixed outlets are safer and more convenient than routinely using power boards or extension leads in a kitchen.

Do not forget the fridge circuit

The refrigerator is easy to overlook because it is not a high-load appliance in the same way as an oven. But it runs continuously, and its outlet can be difficult to access once cabinetry is installed. Its location, connection and circuit arrangement should be settled before the cabinetry plans are finalised.

If a fridge is likely to be moved, upsized or replaced with a plumbed model, say so early. A small change to cabinetry or appliance choice can affect outlet positioning and other service requirements.

Plan outlets around benches, islands and appliances

Electrical work follows the kitchen layout, so electrical planning needs to happen alongside the cabinetmaker, builder and plumber. Waiting until the cabinets are installed limits options and can mean opening finished surfaces to move a power point.

Mark every outlet on the joinery drawings. Include bench outlets, fridge and dishwasher outlets, appliance-cupboard outlets, pantry outlets, rangehood connections and any island outlets. Check that they will not be blocked by a splashback upstand, drawer, pull-out bin, overhead cabinet or appliance.

An island deserves particular attention. It is often the main preparation area, which makes it a natural home for a mixer, charger or serving appliance. It may also contain a sink, dishwasher or cooktop, each with its own clearance, connection and routing considerations. The electrician should coordinate the cable path before flooring, cabinetry and stone are installed.

Avoid placing outlets where cords are likely to cross a sink, cooktop or walkway. Power points around wet areas must be positioned appropriately, and a licensed electrician can advise on compliant locations for the final layout. A neat plan is not just about appearance. It reduces damaged leads, awkward access and reliance on adaptors.

Check switchboard and supply capacity early

Adding an induction cooktop, wall oven, dishwasher and extra kitchen outlets can significantly increase the demand on an older home. Before committing to all-electric appliances, have the switchboard and incoming supply assessed. This is particularly relevant for homes with older fuse boards, limited spare ways, electric hot water, ducted heating or future plans for solar, batteries and electric vehicle charging.

A circuit plan is only as sound as the supply feeding it. The electrician may find that the existing switchboard needs additional protection devices, more circuit space or an upgrade before the kitchen work can proceed. In some properties, the consumer mains or connection arrangements also need review.

This is not necessarily a reason to scale back the renovation. It is simply better to identify electrical upgrade work at the quotation and design stage than after new cabinetry has arrived. Where supply work is required, a Level 2-certified electrician may be needed for work involving the connection to the electricity network.

Build in safety protection and access

Modern circuit protection is a core part of kitchen planning. Depending on the installation and required work, circuits may be protected by safety switches, often using RCBOs that combine residual-current and overcurrent protection. Your electrician will determine what is required for the altered installation and how it integrates with the existing board.

Also consider access for isolation and maintenance. Appliances such as cooktops, ovens and dishwashers should not leave homeowners guessing which circuit to turn off in an emergency or force a technician to remove fixed joinery for a basic service task. Clearly labelled circuits and sensibly located isolation points make a difference long after the renovation is complete.

Lighting should be part of the same conversation. Task lighting under overhead cupboards, practical general lighting and lighting over an island can transform how a kitchen works. Put switches where they make sense when entering the room, and consider whether separate switching for task and general lighting will suit the household.

Allow for the next appliance, not just this one

Kitchen plans often change between design and installation. A gas cooktop may become induction, a standard microwave may become an integrated unit, or a future owner may want a boiling-water tap. Leaving reasonable capacity in the switchboard and considering a pathway for future cabling can reduce disruption later.

That does not mean installing circuits for every possible gadget. It means making informed allowances where future changes are likely, especially during a full renovation when walls and ceilings are already open. The right balance depends on budget, the age of the property and how long you expect to stay there.

For rural properties and older homes, it is also worth discussing voltage issues, long cable runs, outbuildings and any previous nuisance tripping. These factors can affect the wider electrical design, even when the immediate project is only a kitchen.

A practical process for planning kitchen circuits

Bring your electrician in once you have a reasonably settled kitchen layout and appliance list, but before demolition or cabinet manufacturing. Provide appliance model numbers where available, including the cooktop, oven and any specialty equipment. Manufacturer specifications can change the required connection arrangements.

At the site visit, walk through how the kitchen will be used and identify existing electrical limitations. The electrician can assess the switchboard, available capacity, cable routes and condition of existing wiring, then coordinate requirements with the renovation team. This is where having one accountable contractor helps keep electrical, data, lighting and supply work from being treated as separate problems.

Before work starts, confirm the outlet plan against the final cabinet drawings. Recheck appliance sizes, door swings and stone cut-outs. A power point that looks fine on an early sketch can end up behind a drawer or too close to another service once details change.

MBK Electrical & Co can assess kitchen renovation electrical work across Canberra and surrounding NSW, from the initial circuit plan through to compliant installation and final testing. The best time to ask about kitchen circuits is before the plaster, cabinetry and benchtops make every change harder.
