$ b& @6 Z5 j9 T4 z7 @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.! o' R0 L* M' A7 a9 L
R# Q( j0 p4 uCurrent-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.2 T8 P4 g" _# }' T0 g
/ J( J" G6 p( V. l# k
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.1 L4 y8 p1 D. N: x/ u. V( O
NOTE: The term is used only with reference to current-carrying parts which are sometimes alive (energized).0 Z# X6 e6 |0 S: U, ]2 W
