下面是我找到的定义：
* S2 m0 H& w! R9 o+ nAlive 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.# g- @/ v8 {: ^! u6 I2 `. g
# m/ W6 ]! K1 b' T/ rCurrent-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., D; L1 p3 j2 g( G
) l$ I/ B! v- O1 \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.. h6 ?; j0 i% z: Q" ]4 ]
NOTE: The term is used only with reference to current-carrying parts which are sometimes alive (energized).
