Currently, electrical wires on the market are generally categorized into different colors, such as the commonly used yellow, green, blue, black, and yellow-green. These wires come in sizes of 1.5 square meters, 2.5 square meters, 4 square meters, 6 square meters, and 10 square meters, respectively. Let's take a look at several sizes of electrical wire for home installations.
For example, how much wire should be used to install a light?
Generally, 1.5 square meters of wire is sufficient for a job, including running all the downlights in a hall. Running 50 to 60 lights is generally no problem.
Because a 1.5 square meter of wire can produce 1500 watts of power, there's generally no problem, even with more. This value is for reference only; actual values are subject to change.
A single light bulb and a 1.5 square meter wire set are no problem. Please note that the set mentioned here refers to a live wire and a neutral wire.

2.5 square meter and 2.5 square meter wires are common in home electrical systems. Many appliances require 2.5 square meter wires. Basically, all outlets in the house can use 2.5 square meters of wire, which can generally meet the needs of household appliances. Of course, some high-power appliances can also be used. (A 2.5 square meter air conditioner in a room is generally sufficient, regardless of whether it's a single unit or a large unit. However, a cabinet air conditioner in a hallway is sufficient.
Hallway air conditioners generally use square wires, and electric water heaters are more common. Note that these two appliances generally require a separate set of wires to connect to the main power box; they cannot be used separately from other appliances. This set of wires only contains the live, neutral, and ground wires. This is common sense, so all outlets must have a ground wire.
The main box generally uses 10 square wires and 10 square wires. This means that when external wiring enters the room, 10 square wires are required to connect to the leakage current circuit breaker.
