How Many Electrical Circuits in a Kitchen? Complete Planning Guide

The kitchen is the most "electrically intensive" room in the house. The induction hob alone can draw up to 7kW! Improper circuit planning leads to breaker trips, overheating cables, or the inability to connect all appliances. Let's check how many circuits a kitchen needs.

Dedicated Kitchen Circuits

Some appliances require their own dedicated circuit:

• Induction hob: 5x2.5mm² or 5x4mm² cable (3-phase power supply recommended)
• Oven: 3x2.5mm² cable, C16 breaker
• Dishwasher: Separate circuit with RCD protection
• Refrigerator: Ideally dedicated circuit (prevents food spoilage during other trips)
• Extractor hood: Can share lighting circuit if low-power

How Many Countertop Sockets?

This is where people skimp most, and regret it most:

• Minimum: 4-6 countertop sockets
• Optimal: 8-12, including USB ports
• Think about: Kettle, toaster, coffee machine, blender, mixer, food processor, charging devices...

Common Kitchen Electrical Mistakes

• One circuit for the entire kitchen – recipe for constant breaker trips
• Sockets only in corners – no power where you actually work
• No socket for the refrigerator – plugged into an extension cord behind furniture
• Too few sockets above the countertop – extension cords everywhere

In Electro Planner, you can drag kitchen appliances onto your floor plan and the app will automatically suggest the appropriate number of circuits, cable cross-sections, and circuit breaker ratings.
