Installation of high and medium voltage distribution is a common practice in the industry when customers own their primary power. Due to the increased risk of injury to those installing and operating high voltage equipment, practices, policies, and procedures need to be in place for the time of installation but also for the maintaining of those systems to ensure reliability and safety.
