Home electrical wiring plan: prepare circuits, controls and connections

The role of the wiring plan in a home project

A wiring plan prepares the installation logic before the build. It helps you understand which controls drive which lights, where the dedicated circuits run and how to organise equipment room by room.

It does not replace electrical sizing, but it makes the need clearer when working with an electrician.

The circuits to anticipate

In a home you should distinguish lighting circuits, power circuits, dedicated circuits for the cooktop, oven, water heater and air conditioning, ventilation and communication networks.

AS/NZS 3000 sets the safety rules; the provision per room is a design decision. Table C9 of the standard (informative) gives the common loading method — about 20 power points on a 20 A circuit, about 20 lighting points on a 10 A circuit. Your plan should make both easy to check, even though the final validation remains technical.

• Lighting and switches.
• Power points per room.
• Cooktop, oven, dishwasher, washing machine, water heater.
• Data, TV, smart home and security.

Keep the wiring readable

Too many lines on a plan can make it unreadable. Better to draw only the important connections, use distinct colours or notes, and ship a clear legend.

Planelico lets you wire the useful elements together and keeps an exportable plan without excessive graphic clutter.
