What specifications are commonly used for household wires? Single core or multi-core? Household wires are divided into copper wires and aluminum wires, and the cross-sectional area can be selected as 1, 5- 16 mm2. There are four flat refrigerators, air conditioners, televisions and washing machines. Whether it's copper wire or aluminum wire, it's better to be copper, and so is the back. It is good to choose 10- 16 flat air conditioner, so you can use it safely. The patch panels are all national famous brands, such as "Bull" row, which is very safe. Single core is good, and the current is large. Multi-core has small current and strong flexibility, and is suitable for frequently moving positions. It depends on your own choice, but the price of single core and multi-core will be a little different. I suggest you make many comparisons.
