The appropriate size of wire for home renovations is a matter of course, as it's crucial for electrical safety. Improper use of wire can have devastating consequences. So, is larger wire always better? Currently, 2.5 square and 4 square wire are two common sizes. Is 4 square wire better? Does the size of wire depend on the power of the appliance? Let's take a look!
Is larger wire always better for home use?
Not necessarily. On the contrary, using only 4 or 2.5 square wire can actually lead to drawbacks. For typical home appliance use (excluding air conditioners and electric water heaters), 2.5 square wire is sufficient. Using only 4 square wire in a home is wasteful. Furthermore, the larger the wire, the greater the load it will carry.
Does the size of wire depend on the power of the appliance?
For general home appliances, 2.5 square wire is sufficient; 4 square wire is not necessary. For typical household use, such as turning on lights or cooking, 2.5 square meters is generally sufficient. It's safe to use.
What appliances require 4 square meter wire?
For example, high-power appliances like water heaters and air conditioners require 4 square meter or larger wires.
Based on the above introduction to square meter wire requirements for home renovations, we can see that for home renovations, 6 square meter wire is typically used for the main wiring, 4 square meter wire for air conditioners, electric water heaters, and outlets, and 2.5 square meter wire for general outlets. 1.5 square meter wire is sufficient for general lighting. For safe use of household electricity, it's essential to install a leakage current detector (RCD) switch.
