What are the minimum circuit requirements for NB kitchen electrical?

New Brunswick's building code requires a minimum of two dedicated 20-amp small appliance circuits for kitchen countertop outlets, plus individual dedicated circuits for major appliances. These are not suggestions but hard requirements that your electrician must meet and your building inspector will verify. Any electrical changes in your kitchen renovation require a permit and inspection through your local municipality.

The two 20-amp small appliance branch circuits serve all the countertop receptacles where you plug in toasters, kettles, blenders, and other portable appliances. These circuits must be split-wired or alternated so that adjacent outlets are on different circuits, which prevents tripping a breaker when running two appliances at once. All countertop outlets within 1.5 metres of a sink must have GFCI (ground fault circuit interrupter) protection, which is a critical safety requirement that protects against electrical shock in the wet environment around a kitchen sink.

Beyond the countertop circuits, each major appliance needs its own dedicated circuit. Your refrigerator requires a dedicated 15-amp or 20-amp circuit. The dishwasher needs a dedicated 20-amp circuit. An electric range or oven requires a dedicated 40-amp or 50-amp 240-volt circuit, while a gas range still needs a dedicated 15-amp circuit for the igniter and controls. The microwave, especially if it is an over-the-range model, should have its own dedicated 20-amp circuit. If you are installing a garburator, that also requires a dedicated circuit.

The Panel Capacity Problem in Older NB Homes

This is where many New Brunswick kitchen renovations hit an unexpected cost. A significant number of NB homes built before the 1980s still have 60-amp electrical panels, and some even have older fuse panels. A modern kitchen with all required dedicated circuits simply cannot run on a 60-amp service. You will need a panel upgrade to 100-amp or 200-amp service, which costs $1,500 to $4,000 in New Brunswick depending on whether the utility needs to upgrade the service entrance as well.

Have your electrician assess your panel capacity early in the planning process, ideally before you finalize your renovation budget. Discovering a panel upgrade is needed after cabinets are ordered is a budget shock that derails timelines. In Moncton, Fredericton, and Saint John, electrical permit processing typically takes one to two weeks. Rural areas served by Regional Service Commissions may take longer.

A good kitchen renovator will coordinate the electrical work with the overall project schedule, ensuring the rough-in wiring is done and inspected before walls are closed and cabinets are installed. The electrical rough-in for a kitchen renovation in NB typically costs $500 to $2,500 depending on how much existing wiring needs to be replaced or extended, not including any panel upgrade. If your home still has knob-and-tube wiring in the kitchen walls, it must be replaced entirely during the renovation, which is both a code requirement and an insurance issue.

Planning your outlet placement carefully during the design phase will save you money and frustration. Think about where you will use small appliances, where your coffee station will be, and whether you want outlets in your island. Getting the electrical right is one of those invisible investments that makes your kitchen work beautifully for decades.
