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.
& A& f2 ]7 b. ]! J1 D8 y6 P# j6 h
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.- f7 T% U% M- { I0 b( \
" l+ R" ^& w7 BDead (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.% {% A8 R+ s, U/ Y
NOTE: The term is used only with reference to current-carrying parts which are sometimes alive (energized).& I! n$ G, d) h \: S% w1 y `) P
