What You'll Learn
Ensure your kitchen wiring is up to code
When renovating your kitchen, it is crucial to ensure that your electrical wiring is up to code to maintain safety and functionality. Here are some detailed steps and considerations to achieve this:
Firstly, understand the electrical code requirements. The National Electrical Code (NEC) serves as the basis for most local codes, but individual communities may have unique amendments and interpretations. Therefore, it is essential to consult with local authorities or a certified electrician to understand the specific code requirements in your area. Electrical codes are updated periodically, so ensure you are aware of the latest revisions.
Next, evaluate your kitchen's electrical layout and wiring. Identify the number and placement of circuits, outlets, and appliances. Common issues in older kitchens include outdated wiring, insufficient circuits, and a lack of Ground Fault Circuit Interrupters (GFCI) or Arc-Fault Circuit Interrupters (AFCI) protection. GFCIs are crucial in kitchens as they protect against electrocution by detecting current and cutting power if necessary. AFCI, on the other hand, detects sparking between faulty wire connections.
To bring your kitchen up to code, you may need to add or relocate circuits and outlets. Each fixed-place appliance should typically have its own dedicated circuit to handle its electrical demands. For example, a modern refrigerator requires a dedicated 15- or 20-amp circuit, while an electric range demands a 50-amp circuit. Additionally, ensure proper spacing between outlets, with a maximum distance of 4 feet between GFCI outlets, and consider adding outlets to accommodate your kitchen workflow and appliances.
If your kitchen has outdated wiring, it is best to replace it with modern alternatives of the same length. This is a complex task that requires professional expertise, so engage a licensed electrician who understands the code nuances and has the necessary tools and experience to deliver a safe and compliant kitchen.
Finally, obtain the necessary permits and inspections. During a major renovation, you may be required to bring your kitchen fully "up to code," which may include obtaining electrical permits and ensuring your work complies with local regulations. This will help prevent delays and ensure your kitchen renovation is safe and functional.

Rewiring before or after renovation
When renovating a kitchen, it is important to consider the electrical wiring. Rewiring can be a messy job, as it may involve lifting floorboards and chasing out walls. Therefore, it is generally advised to rewire at the very start of the renovation process, before any new fittings or decorations are installed. This will ensure that the cables are safely in place and ready for any further installations.
One reason to rewire before renovation is to future-proof the kitchen. By running appropriate cabling during the rewiring stage, you can position it conveniently, either under the floor or above the ceiling. This will allow for greater flexibility in the future, as these cables can be relocated to suit the customer's design preferences.
Additionally, rewiring before renovation can help avoid any cosmetic damage to the new kitchen. If rewiring is done after the installation of new fittings, there is a risk of breaking or damaging switches, sockets, or faceplates. Rewiring beforehand can also help to identify any wiring trouble spots that may have been caused by the previous homeowner, such as rigging wiring for basement lighting into the kitchen circuits.
In some cases, rewiring may be necessary to bring the property up to code. Older homes, in particular, may need updates to accommodate modern appliances and prevent risks like appliance damage, electrocution, or fire. It is important to consult with a certified electrician to create a plan that ensures the electrical layout is safe and functional.
Overall, while there may be exceptions, rewiring a kitchen before renovation is generally advisable to avoid potential issues and ensure a smooth and efficient process.

Number and placement of electrical outlets
When renovating a kitchen, it is important to carefully consider the placement of electrical outlets to ensure functionality and safety. The number of outlets required will depend on the appliances and lighting fixtures in the kitchen. Here are some key points to consider:
Firstly, it is crucial to ensure that your kitchen wiring is up to code. This is especially important for older homes, as they may not be equipped to handle the load of modern appliances. A certified electrician can help you determine if your wiring needs to be updated to meet current standards.
In terms of outlet placement, it is recommended to have outlets placed no more than four feet apart from each other. This is because appliance cords are typically two feet long, and having frequent plug-in points will prevent the need for stretching cords. On shorter walls, consider placing outlets every 2-3 feet, especially near counter ends and corners. If you have a kitchen island, adding an outlet there can be useful for small appliances.
Additionally, certain appliances require dedicated circuits and specific outlet types. For example, a stove or oven range typically requires a dedicated 50 amp, 240-volt circuit with a special range outlet. A microwave also often needs its own dedicated circuit, usually a 20 amp, 120-volt circuit. Appliances with motors, such as a garbage disposal, should have their own electrical circuit, typically a 15 amp, 120-volt circuit. The garbage disposal circuit can sometimes be shared with the dishwasher, depending on local electrical codes.
It is also important to consider the lighting plan when placing electrical outlets. LED lights are a popular choice for kitchens, as they are long-lasting and can provide good task lighting. Under-cabinet lighting can be useful for meal preparation, and overhead lighting can illuminate the entire space.
Lastly, when renovating a kitchen, it is advisable to rewire and install outlets before any cosmetic work begins. This allows for appropriate cabling to be run conveniently under the floor or above the ceiling, future-proofing the space. It also helps to avoid issues with floorboards and walls, as rewiring can be messy.
