1) overhead or underground electric supply lines up to 750 volts [the threshold cited in Zl33 (U.S.) that requires 10-foot (3.05 m) separation without specialized training. etc.]. typically 120 to 480 volts. used to deliver electricity to end users (see secondary. distribution line. and service line). 2) electrical power Junes used in landscape lighting. with operating voltages between 12 and 24 volts. 3) other electrical power lines with operating voltages typically at or below 24 volts. such as alarm systems. signaling systems. and telecommunication systems (contrast high-voltage lines).
