下面是我找到的定义：
4 L- G- d- Y5 q" MAlive or live (energized). The term means electrically connected to a source of potential difference, or electrically charged so as to have a potential significantly different from that of the earth in the vicinity. The term "live" is sometimes used in place of the term "current-carrying," where the intent is clear, to avoid repetition of the longer term.: ]7 M- e1 C h
& i7 W; G" d4 `Current-carrying part. The term means a conducting part intended to be connected in an electric circuit to a source of voltage. Non-current-carrying parts are those not intended to be so connected.
M; J! A9 E; N$ W9 [ V* H. G1 i- G! B' R: H
Dead (deenergized). The term means free from any electrical connection to a source of potential difference and from electrical charges: Not having a potential difference from that of earth.: c3 d5 i: ^1 k0 N1 ]5 x% p
NOTE: The term is used only with reference to current-carrying parts which are sometimes alive (energized).
