Ungrounded conductors shall be attached to insulators or terminated in approved high-voltage cable couplers (which include ground wire connectors) of proper voltage and ampere rating. The method of cable termination used shall prevent any strain or pull on the cable from stressing the electrical connections. The enclosure shall have provision for locking so only authorized and qualified persons may open, and shall be marked "DANGER-HIGH VOLTAGE."
