12-02-2024

Electricity is indispensable in daily life, and the specifications of electrical wires in home decoration are usually determined by the connected equipment or electrical compliance. The commonly used is BVR wire. Taking BVR wire as an example, the following are some scenarios where different wire specifications are usually recommended:

2.5 square meter BVR cable can be used for low-power lighting, wall sockets, and small household appliances with a typical load not exceeding 10A.The 4 square BVR wire is suitable for appliances with high total power, such as high-power air conditioners, electric ovens, and other heavy-duty household appliances.However, in certain special scenarios, specifications exceeding 4 square meters of wires may be required. For example:

1. High power appliances, such as electric water heaters and central air conditioning, typically use larger wire specifications.

2. Long distance wire connection: If the wire needs to travel a very long distance, such as in large residential buildings, larger wire specifications may be needed to ensure voltage stability and prevent energy loss.
