How Much Wire Goes Into a New House

 Complete electrical house wiring with wire size for all rooms.

If you're having a new house built, you might be wondering how much electrical wire is needed to complete the electrical work. The amount of wire required varies depending on the size and layout of the house. In this blog post, we'll explore how much wire is used in a typical new home construction project and what factors influence the amount.

As a general rule of thumb, you will want one foot of wire per square footage that is covered by your house. This does not include the wiring used in any detached structures such as a garage or shed. If those are present, additional wiring will be needed to accommodate them. You will also want to allow approx. 5% for waste.

Electrical wire, or building wire as it is commonly known, is generally sold in 100 meter rolls.

If the layout of your home is complex or has several levels, it may require additional wiring. For example, a two-story house will need more wire than a single-story home with the same square footage. The extra wiring is needed to ensure all areas of the house have access to power and are correctly wired for safety.

In addition to the size and layout of your home, other factors affect how much wire is required. The type of wiring used will also affect the total amount needed. For instance, homes built with copper wiring require less than those using aluminum or other types of wiring. The quality of your electrical system and its components can also determine the number of wires you'll need to complete the project. And don't forget, the number of outlets and switches in your house will affect the amount of wire needed. The more outlets and switches you have, the more wiring is necessary to ensure proper operation.

In short, calculating exactly how much wire is required for a new home construction project can be tricky. Over the years, we've found it is better to overestimate than underestimate, as there are always unexpected complications that occur on new home builds. Once you know how much wire is needed for the house you will be able to calculate how long it will take to wire the house.

It's important to ensure you have enough wiring to meet all safety requirements and power your home correctly. With careful planning and calculations, you can ensure that the electrical work in your new home is done right.
