Alive 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.3 `# f1 ~3 Y2 a3 O/ ?+ I

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./ u4 Q0 S4 k% T; F
NOTE: The term is used only with reference to current-carrying parts which are sometimes alive (energized).
