Wiring is all the wires inside a building, a car, or a machine, taken together as one system — the electric veins hidden behind the walls and under the floor. Because it names the whole set and not the separate pieces, it is uncountable: say the wiring, some wiring, a lot of wiring, and never a wiring or two wirings. If you need to count, count the wires or the cables.

Wiringwiring is all the wires是指一棟建築、一輛車或一台機器裡 inside a building, a car, or a machine所有的電線, taken together as one system合起來當成一個整體來看 — the electric veins hidden behind the walls and under the floor也就是藏在牆壁後面、地板下面的電線血管。Because it names the whole set and not the separate pieces因為它指的是整個系統，不是個別的一條條電線, it is uncountable所以是不可數名詞: say the wiring, some wiring, a lot of wiring要說the wiring、some wiring、a lot of wiring, and never a wiring or two wirings絕對不會說a wiring或two wirings。If you need to count如果你需要數數量, count要數的是 the wires or the cablesthe wires或the cables這些字。

Two more uses are worth knowing. First, wiring is also the -ing form of the verb wire, so it can name the act of putting the wires in: Wiring the whole flat took three days. Second, people use it about the brain and about human nature — It's just how he's wired, meaning that is his built-in character, not something he chose. Both of these are common and natural.
